Limestone Vinegar Test aka Acid Test for Carbonate Minerals

This is a simple test to determine if rocks contain carbonate minerals that could adversely affect the PH levels in an aquaponic system. It is sometimes called the "limestone vinegar test"
This test uses Lava Rock (Scoria) in the first sample with negative result. And Limerock (Limestone) in the second sample with a positive result.

thanks. I'm new to all this and I need to put a few rocks in my wildlife micropond, but I am in the Most Karst Area and the water does not need any more pH points!

Hey there I've been wondering, how much vinegar would I need to dissolve a large ,limestone rock? Let's say its around 24 tonne cuboid buried somewhere in a Spanish desert?

Thanks for the video. Our aquaponics pre-fish pH is 8+ pH, despite well water (even after soda ash injection) running 6.6 from the tap.
There is CO2 off gassing for our water probably, since pH does rise as the tap water just sits for 24 hours.
I saw similar small bubbles with the lava I used. BUT the same thing happened in plain water. I agree, those small bubbles that sit there, staring at you, inducing carbonate-paranoia are just trapped air in the lava... Same experience for me, that no ongoing reaction-like bubbling occurred. I'm checking hardness levels next, since I might be dealing with too much buffering...

Well I enjoyed the video....

Hello, I found your video and I wander if i could a part of this video on my youtube video?

Can I use drano to determine rock ph or acidity levels
