Co2 level will be much lower, as it increases Oxygen level.
And other tank has much higher chance of having good level of Co2, as we are not messing with Oxygen level.
@@akshaybedared I think exactly the same , the water is saturated with O2 and low levels of CO2 are causing the absorbition problems and makes sense the tests show it.
Test..
KH x PH = CO2
If the device has an effect on free floating bacteria, like cyanobacteria, maybe it somewhat prevents the build up of beneficial microflora on the surface of the leaves in a new aquarium. And the plants dont like that. But this device is so ambigious im just shooting in the dark. I use it as an oxydator, i find it better than an noisy air pump.
Honestly I think it would be interesting to move the sterilizer into the other tank and run the experiment for another month. See if the plant growth changes in both tanks. Also you can see if algae will be reduced.
Fully agree.. This would be the right approach to see if this observation is significant or coincidenceđ
Hi guys! I watched from TV and opened my laptop to write a comment about the same thing đ I'm voting to move sterilizer from one tank to another tank too.
best, and if works i will buy it, besides if works twinstar should sponsor
This was my first thought as well.
I'm up for that.
The "steriliser" is an actual "oxidiser", which means it increases the level of oxigen in the tank. The algae reduction is due to the fact that some types of algae are more susceptible to the oxigen and thus they get damaged and destroyed. The side effect on the tank is that the excess oxigen is able to oxidise some minerals dissolved in the tank, thus altering the state of those minerals and making it slightly more difficult for plants to absorb them. Iron is expecially sensitive to oxigen and this is why you see large leaved plants all curled and deformed. Also, the increase in growth publicised by the sterilised might depend on a combination of 1) the reduction of algae activity that avoids nutrients waste and 2) the increase during night of oxigen that helps the plants breathe when there's no light. I would say that 50% more growth is an overstatement and needs to be proved by the provider...
Very interesting theory. My immediate explanation looking at the plant curling and slower growth was CO2 deficiency compared to the other tank. And my explanation for that after noticing a ton of surface biofilm was that the inline injected oxygen (which is supposed to help bacteria) helped the surface bacteria to overtake the water surface, thus severely limiting the gaseous exchange with the atmosphere. In other words, the ecosystem is getting the oxygen from the sterilizer so it doesn't need it from the atmosphere. This gives an advantage for bacteria to thrive everywhere including the surface without choking itself from doing so. This in turn blocks CO2 from sufficiently entering the system and puts plants at a growth disadvantage. If this theory is correct, then the sterilizer definitely works but with a catch: it's meant for high tech systems with CO2 injection and preferably surface skimming; something that the manufacturer should definitely mention. Just guessing here and your theory is also interesting although I lean more towards mine because of how rich and new the substrate is which makes me doubt that it's a water column based nutrient deficiency (also he mentioned that he's only dosing NPK to the water column). It looks to me like very typical CO2 deficiency.
I think your on the right track. but I don't think it's one or the other, its both. The electrolysis that creates/frees the oxygen is a sterilizer who's by-product is O2. And the O2 becomes a sort of Ozone-mini. (Are they still a thing in marine aquariums?) I guess my next question would be, How much O3 does this give off? If O3 is created that would open a whole new can of worms.
@@marvenmema From my experience this rings true. I attempted a dark-start for 4-6 weeks prior to turning on the sterilizer. My thought was no light, no algae, sterilizer not needed. In retrospect, My brown algae established itself during that period using the minimal ambient light available. And therefor its effect on the browns was minimal because it was not free floating when the unit was turned on. The first greens I saw were identical to those in the video (2:46) they started forming anywhere the driftwood broached the surface. Of coarse any time I wasn't jonnie on the spot with its removal, meant the filters would pull pieces off and the pieces would settle-in elsewhere. Also, surface skimming was required and was the first job of the day, every day. (not happy with the Rio Flow Prem. Too fiddly for such a piss poor mounting system) Currently, 6-8 weeks after removal I have no surface film, no skimmer.
Plants most effected: 1. Bacopa Monnieri (stunted growth, small leaves) - new leaves have doubled in size since removal. 2. Cryptocoryne Mioya (RIP) 3. Nesaea Pedicellata "Golden" , and Alternanthera Reinekii mini (both had similar results to your Reinekii) - I moved both thinking it was low light. Around the same time frame as removing the sterilizer. The Reinekii quickly became the most beautiful plant in the tank. The Golden went dormant from the move, but its still alive.
Plants least effected: Crypts in general (3 of 4 sp. did well (see disclaimer))
Disclaimer: one of my plant suppliers decided to send over 40% DOA on $350 plant order. Honestly the rest of the order wasn't much better but I was able at least save them. Thankfully I had over ordered and they made it right, and earned being my first stop when I need something. (just checked my records the three crpt. sp. that did well were from a different supplier.)
Sorry, my ADD kicked in.
Hypothesis: The sterilizer uses electrolysis to damage the cell wall of free floating algae. The by-product is that it also breaks the CO2 bond. Freeing the O2. Requiring an increase of CO2 fertilization. But be warned increasing CO2 fertilization will kill your fish.
If true, Professionals only.
@marvenmema @diiin85 Thank you both for your valuable input. It helped me a lot. I have a heavily planted aquarium with CO2 (came back to the passion after a 15 year absence, so I'm practically a newbie again) and I was wondering about the relevance, ups and downs with this product. Regards from Portugal!
Everyone says those sterilizers are snake oil, but you saw an actual difference, incredible!
INTERESTING AND FRUSTRATING! Merry Christmas MJ!
I noticed that running an air diffuser at night over using this sterilizer allowed my tank to grow properly and not have many algae issues. Nice shirt btw!
Heavy dosing schedule next! Thanks for all the great content.
I think hydrolysis from the twinstar is breaking down the fertilizer nutrients, hydrolysis is a chemical reaction that can break down certain substances, including plant fertilizers, when they are dissolved in water. In some cases, hydrolysis can lead to the breakdown of plant fertilizers into their individual components, which can then be absorbed by plants. However, the extent to which hydrolysis affects plant fertilizers will depend on the specific type of fertilizer and the conditions in which it is applied. Some fertilizers are more resistant to hydrolysis than others, and the pH, temperature, and other factors can also influence the rate of hydrolysis.
I think this also could be the reason you see a reduction in algae, less nutrients available means less algae.
Exactly what I was thinking too :)
Very interesting! Thanks Mark!
You can't break fe2+ down though? It's an element / ion. Good point though
Absolutely right. The less nutrient, the less algae. But just as little plant growth.
"Less nutrients available means less algae": how would you explain all the algae free tanks on EI dosing then? And how would you explain the deficient plant growth despite all of that fresh aquasoil and substrate layer that plants could still feed from? Also how would you explain the guys that do use the sterilizer (like Erkut), dose a good amount of ferts and don't suffer from the hydrolosis issue you described nor algae? Sorry but folks are quick to blame nutrients for everything when 99% of the time nutrients are not the problem. Nutrients are your friend not the enemy. This looks to me like typical CO2 deficiency. And looking at the severe case of surface biofilm in this tank (probably the bacteria is thriving in the surface and everywhere thanks to the constant supply of oxygen by the sterilizer, just as advertised by the manufacturer actually) AND lack of CO2 injection and surface skimming, I would say the tank is simply CO2 deficient. As Tom Barr says, 90% of algae issues are rooted in CO2 issues.
I love the wall cabinet that you put the small aquariums on! May I ask where itâs from? Iâve been looking for something like this, but I wasnât sure if the planks are able to hold the weight of the water.. but yours seem to do just fine :)
Hey Mark. What about just removing the steriliser and see if the plants improve? Great channel. đ
Wonderful experiment update đđ»
I like the idea of inducing algae and seeing if the twinstar does anything. People probably buy it when they have an algae issue in the first place, not before they have the problem
@MJAquascaping, I think this was a success. At least it confirms some of the issues I was having.
Re-assessing my previous recommendations: MAY be worthwhile if you are setting up 3-4 aquariums a year. Even then I would recommend waiting for an updated version with timer features built-in. If they can make these upgrades without affecting the price a wider market MAY be warranted. (not an expert)
Canât believe you posted this video right now :-) I am running a new tank since around 8 weeks. Everything is setup perfect, as usual. However this time I am using a twinstar and I have big issues with Plath growth! I turned it off right now, curious to see what will happen :-)
Btw I never had issues with Plant growth within the last 20 years :-)
Sterilizer does exactly what it says it does lol. Both good and bad beneficial bacteria get nuked. Than your tank will take forever to set into itself. Uv sterilizers are mainly used for exhibits or anything that actually requires uv sterilization. Planted tanks do not need sterilization thats for sure. You would think its nutrients but its a mix of everything being nuked. In my opinion, not needed for planted tank. Maybe use it for a hospital tank
I have in mind that these sterilizers break up chelates, e.g. the chelates in iron fertilizers, but potentially also others. If this true, it could influence nutrient uptake, but also release of chelated compounds which are more toxic to the plants..(?) Thank you for the video!
I tried the Twinstar and the Chihiros Doctor on 2 tanks, and on both I had a lot of blue green algae. I think that it kills well green algaes, but if the proteins and ammonium from stressed plants are still there, this promotes more annoying algae that these devices do not kill well (black algae, blue green). It is also a very interesting finding that plants would not grow that well. Thanks a lot for your video! It would be great to leave for a month the twinstar in the other aquarium just to compare.
I've used Twinstar sterilisers on all my tanks so can't give an honest answer on if or how much they work - happy to see that you got noticeable results though đRegarding further experiments on this: The main reason I'm using sterilisers is for the different kinds of extra oxygen that's being generated and how this in theory would promote the beneficial bacteria. Maybe another experiment once the tanks have stabilized would be to dose them with a good amount of ammonia in order to see the tanks response to it. Maybe not a super scientific approach but I would definitely find it interesting.
Thanks for a great and interesting experiment thus far! :)
Great video mate I am learning a lot from you thanks
I red, the twinstar "destroys" the fertilizer, so the algegrow is reduced but it reduces the plantgrow aswell.
Maybe you do a ICP analysis with both tanks after same fertilizer dosage.
I've had a Chihiros Doctor, which is kinda the same as Twinstar thingy. I've never noticed any difference in algae growth, but your experiment proves otherwise.
And that pricing of those :) It could be ok if the initial cost would be high and spare reactors cheap. But it is those ractors' cost what make this device ridiculously expensive..
Anyway, great experiment and i'd like to see next phase :)
love these experiments
great video and review of the sterilizer, i always wondered about them, but don't have any algae issues in my planted tanks as they're quite balanced. on the opposite, any suggestions on growing green walls of algae for shrimp only or shrimp breeding tanks? thanks so much!
Interesting experiment but according to the twinstar manual, the reactor is supposed to be installed 10-15cm below the outflow. It mentions water flow is important. Anyway, I just installed the M5 version in my new tank. Maybe I could share more after a month or two
Huge difference in plant growth even though tests ok. Weird! Because I am not as experienced as you, if it were my aquarium, I would be taking it out by now and returning it to manufacturer. I would rather clean algae than replace plants. But that's just me. Clearly the sterilizer is doing something unhealthy to the plants. I would be interested to see a couple more weeks of experiment. Only because the product makes such a huge statement about being healthy for plants and we are not seeing that. Thank you for taking time to do these experiments and videos. Very much appreciated.
Interesting experiment. The fact that there's so little nutrient in the water column like iron and phosphate is certainly going to cause the plants to struggle. And if the plants aren't at their best, that will certainly allow algae to overtake.
Maybe repeat the experiment from scratch but ensure the plants have everything they need.
Would be cool to see the difference between high-end and cheap fertilizers!
I was looking for information before I made a decision on buying this. I will instead invest in a good lighting LED system. Thank you!
Very interesting results đ€
I think we should continue the experimentđ
interesting!
Great video got me thinking
I think that the sterilizer aquarium have co2 deficiency, so I will be cool that you do an experiment dissing daily and to see if the sterilizer affects the co2 levels
I think you should contact twinstar costumer service and see what they say as to why plant growth was worse. I assume they will blame lack of nutrient dosing and then continue or restart the experiment following their instructions on both tanks.
You obviously have never seen their instruction manual. That's where customer service starts.
@@donl7596 clearly
I do ponder if it's because you lean dose and the Twinstar quite possibly neutralises ammonia (even transient ammonia that may not be picked up on a test) and that's why it had that effect on the plants.
Would the results have been different, especially the plants in the Twinstar tank, if they were both dosed to EI levels?!
Hi MJ , thanks for the vid.
Iâve only really seen twinstar sterilisers used with added co2 . Perhaps carry on the experiment but add Co2 to both ?
Both tanks have CO2 injection!
@@MJAquascaping my bad , sorry.
Hello MJ I installed my Nano+ 3 days ago and I had to increase the Co2 on the 2nd day because the ph started to rise, I also noticed the water more crystalline
update?
Did you see any poor results like in this video? Especially the red plants.
It would be interesting to test if it breaks down the iron chelate like uv-c does. When I run a uv-c the iron chelates in my aquarium drop from 1 ppm to 0 within 1 day. Would you notice a difference with this steriliser?
I think any algae control method will have some impact on all the plants in the aquarium.
if im correct this is electrolysis machine. it divides H2O in hydrogen and oxygen. quite expensive as you can easily make it at home. Just be sure to use graphite plates. And not inox or copper or anything alike.
Keep it i want to know if it works in longueur term
1. M5 is for aquarium between 30-50 liters if it is set to mode 1. It is too strong for 20 liters aquarium that you have place it.
2. Twinstar does not advertise to place the reactor on vertical position. You did that because there is a rumor that this way the reactor will last longer. Even if this is the case, it is not the way that the manufacture advises to use it. And since you place it vertically, that means that you believe that the positioning plays some role in the way that it works (I do not think it does but when you do an experiment you start by the book and then you start changing things).
3. You can change the lights between the 2 aquariums. Being the same lights from same manufacture does not mean that there is no difference in Par levels. (Or you can measure the output to check it).
It should be interesting to test conductivity in both tanks. Let me know the result in comment please đ
Can you do an experiment using aquarium salt with the Twinstar steriliser? I think it might create chlorine.
Can you make a experiment with and without fertiliser
i'd take the divece out, to see if plant grow increases. maybe even put device on the other tank to see what happens there.
kind of sound like the device "kills" nutients in the water colum. but thats just a random guess.
fijne kerstdagen ;)
It is possible that the excess oxygen generated by the twinstar is oxidizing some nutrients such as iron, causing precipitation of the nutrients and making them unavailable for plant consumption.
I don't know exactly how the twinstar works, but it may be generating ozone as well. Ozone is harmful to all living things and could be burning the plants. But this is just a guess.
I see a big difference from the TS Sterilizer.
1. Plant growth is less.
2. Plant colors are pale.
3. It killed most of the algae after one month.
My best guess is that the sterilizer somehow burns up most of the nutrition or minerals in the water. Hence the slow plant growth and almost no algae.
If the sterilizer ionized the water (make it more sterile) you can measure it with PH, it would be more alkaline .
I guess there will be a difference between those two waters.
Best step is to measure everything also minerals. to see what happened.
Good thing to find out and really good to test it even better.
For the look of it now, it would not be beneficial for the aquarium.
What about the CO2 levels and/or pH?
My experience with these is that they're good for preventing algae but once algae is present it's not able to catch up. When I install these with a new tank and leave it while the tank grows in I don't see any noticeable algae.
It makes sense to me. Algae, mosses and plants all require the same things, light, nutrients, water, co2 etc.
Adding or removing anything will always affect all.
So i cant imagine how something can promote growth on plants and reduce growth on algae.
Without targeting one select group with specialised chemicals.
Thank you for the much needed observastion. I'm involved in research of hydrolysis in cellular matter in general. Electrolyzed water, also known as ionized water or electrolyzed oxidizing water (EOW), is produced by electrolysis, a process that passes an electric current through water containing dissolved salts. This process creates two separate streams: alkaline ionized water and acidic ionized water.
Alkaline ionized water, which is often used for drinking purposes, is generally considered safe and non-toxic. It typically contains increased levels of dissolved minerals like calcium, magnesium, and potassium, which can be beneficial for human health in moderation.
On the other hand, acidic ionized water, which is primarily used as a disinfectant and cleaning agent, can have varying degrees of toxicity depending on its chemical composition and concentration. Acidic ionized water is produced by electrolyzing the water with a lower pH, resulting in the formation of hypochlorous acid (HOCl) and other oxidizing compounds.
While hypochlorous acid has antimicrobial properties and is effective in killing bacteria, viruses, and other pathogens, it can be harmful in high concentrations. Prolonged exposure to high levels of acidic ionized water can irritate the skin, eyes, and respiratory system. Additionally, ingestion of concentrated acidic ionized water can be harmful and potentially toxic.
It's important to note that the toxicity of acidic ionized water depends on its concentration, pH, and the specific disinfectant compounds present. Diluting or using appropriate concentrations of acidic ionized water for cleaning and disinfection purposes is essential to minimize potential risks.
In summary, alkaline ionized water is generally safe for consumption, while acidic ionized water can be toxic at high concentrations. Proper usage, dilution, and adherence to recommended guidelines are crucial to ensure safety when working with acidic ionized water.

Is the sterilizer messing with the a fixation cycle? If it's killing off those bacteria... that could be causing an issue, maybe?
Any update on this experiment. I have the nano plus and Iâm having the same issues as well. I took it out last week and my rotala wallichi is already doing better
Tests and comparation...
GH
KH x PH = CO2
Oxidation maybe cause decrease CO2 level
Im wondering if maybe you are only supposed to use it at night, while plants breathe oxygen, and use co2 by day, would that have not stunted the plant growth and still kept the algae at bay?
Or was it intended for tanks 10x this volume which would have 10x the nutrient substrate that would need to be oxidised before inhibiting plant growth?
That's interesting experiment. It makes my wonder there's something related to CO2 maybe.
I think you could try this: take the sterilizer out from the original tank and put it in the other tank and see what happens.
Does the original tank bounce back? Does the other tank where you would put it stops growing plants?
Keep everything else the same...
Good one! I'm definitely going to try that!
@@MJAquascaping glad I could add some ideas đđ
â@@priyankardas2668 Namaste.
The higher oxygen might mean that there is more bacterial activity which would lead to less nutrients in total, an experiment where you change the steriliser to the other tank
well... this sterylizer also fall down chelated micro, so maybe it could be because of this? maybe it was a fertz issue related to micro excess in the aquairum withouth the sterylizer? I don't know.. i'm using the yotta+ and I have algae now, but deons't had algae in past so I have no uidea maybe this is not effective at all about algae directly but it could be positive or negative because side effects we have to study, what do you think about?
I like the second option
Could you move the sterilizer to the other tank and see if that makes a change to the plant growth?
Just did that!
More importantly - where did you get your shelving unit! ;-P
i have a twinstar sterilizer but my plants grow too fast. I have to realistically trim my stems every week. My moss constantly grows new buds and my pinnatafida keeps spreading. Idk why but it seems to have no effect on my growth speeds.
Thanks for sharing! I'm curious what fertilisers are you using?
You need to read into the mechanics of these things. They separate the H and O and this causes the creation of hydrogen peroxide among other things, it can also cause the free H or O to attach to other elements in your water. H and O don't like being in their pure forms, they like to attach to things, especially each other. Try a test comparing the twinstar to a small hydrogen peroxide daily dose.
The one with the sterilizer has less growth. Not clue what that is because I don't know anything about the sterilizers and how they work. What is the plant in the back left? I don't see that in your list of plants.
Plant in the back left is mayaca fluviatilis
@@MJAquascaping Thank you sir!
Hey MJ, my immediate first guess looking at the "deficient" plants, would be CO2 deficiency. In other words CO2 being the limiting factor compared to light and nutrients. Does the tank with the sterilizer have a worse case of surface biofilm (encouraged by the inline injected oxygen perhaps and limiting the CO2 exchange with the atmosphere) compared to the other tank? I could be wrong, just guessing. I did noticed a lot of biofilm at a certain camera angle in the video. If this theory is right, it could mean that the injected oxygen which is supposed to help bacteria ALSO helps surface (biofilm) bacteria so you need good surface agitation and skimming. This also means that the manufacturer should probably mention this "inconvenience" to customers and that the sterilizer is better suited for high tech setups with CO2 injection.
The althernanthera reinekii mini is melting on the sterilized water is that correct?
no itâs not. I paused the video :)
What soil did you use?
I'd remove the steriliser, increase light intensity, dose fertilizers heavily, develop algae and after a week-two add the steriliser back. It would give You answers to two questions: 1. can the plants "come back" in the left tank and 2. will the device work with killing algae.
Mark I have likewise experimented and not been convinced the algae reduction (largely of green algae) is worth the wider impact on plant growth. I suspect because many algae species have similar requirements to plants, and that imbalance gives competitive edges to one or the other, that chemicals which inhibit algae are likely to do the same to plants. What electrolysis does to nutrients is a question for someone with more chemistry training than I myself have, but, I fear oxidation of trace elements may be a part of what is going on, Iron quickly becomes oxidised in an aquarium, the steriliser may be exacerbating that. Red plants in my experience are very sensitive to excessive Nitrate and are Iron hungry, factoring that in with CO2, lighting, substrate and tap water chemistry is not easy, but rapid oxidisation of Iron would be very detrimental to their cells. There are so many algae species that one species is likely to do well with high oxygen, hard water, high Phosphate or warmer temperatures. This is great material but I think you need to probably try and control more variables. Probably not practical in a domestic environment.
Interesting to note that so far as I know: JBL, Dupla, Fluval or Dennerle do not sell/make/market electrolysis sterilisers. It would be helpful if someone from their technical teams would contribute.
Take the sterilizer out and see if they plants start growing like the other tank I think that should be the rest of this experiment
My first thought (before finishing the video) is that the Twinstar is creating more agitation in the water, and adding oxygen to the environment and perhaps something in that process is depleting the CO2 which is causing the poor plant growth? Maybe just more CO2 would solve the problem?
Obviously the plants would grow less in the tank with the Steriliser I thought when you set up the tank as the plants want c02 and more oxygen in such small bubbles takes the c02 away from the plants
Go on with adding more ferts.! Don't stop the experiment, cuz is not concluded because the lack of dosing!....
Mid video comment:
amateur guess: does the hydrolysis affect surface exchange of CO2?
more educated guess: O2 and potentially H2 being added into the tank causes spontaneous reactions with nitrogen and potassium and their various molecules...a quick google search brings an interesting article:
Rapid hydrolysis of tertiary isoprene nitrate efficiently removes NOx from the atmosphere - I'm certainly no chemistry expert, but it does make me wonder if hydrolysis affects the available NO3.
Have you tried taking multiple water tests from both tanks, before, during, and just after the twinstar sterilizer activates? I'd be interested to know if nitrate or another molecule is changing ppm from the sterilizer
Edit: looks like MST posted something similar earlier; definitely interested to see what comes next in this experiment series
I think its a waste of money..thanks for the experimentđ
I think the point made about oxidisation is a good one. But, I think the steriliser is saturating the water in oxygen this means less dissolved CO2, the less CO2 in the water the less plant growth and uptake of nutrients which will result in less plant strength, colour etc. The control tank has no added oxygen, the plants are getting enough CO2 from their own respiration and that of the livestock, during the photo period the plants will take up all the excess CO2 and convert it to healthy plant growth and oxygenation. I think you should run the experiment another month without any ferts, the livestock should provide enough trace elements and it would be interesting to see what happens.
If the steriliser is increasing oxygen saturation could this be reducing the amount of CO2 the water can absorb?
please tell me what camera do you use?

This is electrolysis, You can do you own for almost nothing with 2 stainless steel mesh separated by few millimeter and any power supply adapter you have around (1.5V up).
I personally think that it is not something that can be use in permanence. I personally use it when I do cleanup or water change and place the âsterilizerâ in a strategic spot where the most water will pass trough the device. My DIY is a 2.5 diameter inch black plumbing pvc pipe coupling 1.5 inch deep where the 2 meshes (dollar store strainer) are separated in the middle by a few millimeter plastic open grid to let the water pass but prevent the meshes to touch together. 2 stainless steel screw & bolts pass trough the pvc pipe and compress tack interdependently the 2 screens (by a little 90Âș flat piece of the screen) and each electrical wire of an old computer switch. Plug and Play!
- You will have to clean up with an old toothbrush to one of the screen that will cover itself with precipitated whitish salts.
Important Facts
âą Water electrolysis requires a minimum potential difference of 1.23 volts, although at that voltage external heat is also required.
- Typically 1.5 volts are provided.
âą Both oxygen and hydrogen gases are clear and odourless.
âą Hydrogen gas is very flammable (e.g. Hindenburg zeppelin disaster)
âą Epsom salt, also known as magnesium sulfate (MgSO4), present in the water help break up the water more efficiently.
- Epsom salt breaks up into charged particles called ions, and these help carry the electric current through the solution.
âą Iron: Ferrous ( +2 ) is soluble in water (use by plants) . Ferric (+ 3) is not . Electrolysis transform Soluble ferrous iron will be oxidized by dissolved oxygen to ferric and settle out as oxides / hydroxides (Unavailable for Plants).
âą Potassium: Potassium oxidation occurs at anode and reduction occurs at the cathode. At the cathode, there are only K+ ions so they reduced and potassium will deposit on the cathode.
⹠Nitrate: Nitrites are oxidized and transformed into nitrates by oxidation. (Great⊠Nitrite is toxic to fish and nitrate absorb by plants)
âą Calcium will form at the cathode and chlorine will form at the anode. This is because positive calcium ions are attracted to the negative electrode (cathode), where they gain electrons to form calcium atoms.
âą Phosphate: In the solution of Potassium Phosphate KH2PO4, the potassium and the hydrogen cations should go to the cathode and the hydrogen ions can get electrons. Also, the phosphate ions should go to the anode and can make insoluble compounds with metal ions having lost electrons at the anode
âą Electrons flow from the black wire (negative) into the solution. Electrons flow from the solution into the red wire (positive)
The process of electrolysis kill pathogens and creates pure water, hydrogen, oxygen, and solid waste by oxidation and precipitation.
Which test kit are you using?
It's from Sera!
1:23 water seems not level??
They split Hydrogen and Oxygen. The Hydrogen forms a dual bond of H2 and floats to surface. The O2 is dissolved into water.
Hi!
Basically (I insist on basically) it is working by breaking H2O molecules with electricity into H (Hydrogen) and O (Oxygen) gaseous molecules and other molecules (Hydroxyde HO- for example).
So you are injecting Oxygen into your tank wich in my opinion remove the co2 naturaly present in your tank even without co2 injection.
In my opinion this is why you seems to have plant deficiencies for me it is a lack of co2.
So if I think is going in is what is really going on then the unit is basically using electrolysis. So you're getting water broken down into two parts hydrogen, and one part oxygen and that is getting dispersed into the water column, and probably doing so very efficiently given the tiny size of the bubbles. But... The side effect of this may be that with so much oxygen diffused into the water is that it's creating a CO2 deficiency causing the plants to starve a little bit which would explain the lack of growth given what looks to be a lot of light. That is all just a guess, though. Also a side thought is.. So there's all of this oxygen getting diffused into the water, what's happening to the hydrogen?
I would say Oxygen overload. If the Co2 and oxygen are out of whack It stunts the growth of plants. Try placing an air stone under a plant, where the plant and air bubbles meet at the water surface and watch as the plant becomes incredibly stunted over coming weeks in this area. This is in my experience anyway. Iâm wondering as because the air micro bubbles are so small, allowing more air to become directly absorbed into the water column and therefore stunning the growth đđ»
Is that just electrolysis
Run it on a timer for an established tank??
this is a great suggestion!
Slower plant growth?
Exactly!
Add ferts and see what happen
Worth it for only controls gdađ€
Put the sterilizer in the other tank to see how fast it dissolve
Co2 !!
It seems like the increased oxygen would impact the waters ability to absorb co2.
â€â€â€đđ
Seems odd they make a statement of enhanced plant growth when this is basically the opposite of adding C02. I wouldn't bother with on of these. Seems like a waste of time.
It works by producing hydrogen peroxide and it's the same as Chihiros Doctor
I paused the video and my guess is: I think the plants look better in the tank without the sterilizer.
is it due to the increase in oxygen level ?
I have no idea!
If there are more oxygen in the water column, that means less Co2 = less plant growth..... i think?
Maybe you should take out the Twinstar and keep things going for awhile. Letâs see what happens to the Twinstar tankâŠ..đ€·ââïž
Plant growth??? Its got to be
