How to maintain GH & KH

How to maintain GH & KH
In todays video we discuss how to maintain GH & KH in your aquarium.
If you are new to fishkeeping you may want to watch my GH KH & pH Beginners Guide video, here is the link: • GH KH and pH | Beginne...
Maintaining GH & KH in your aquarium is very important, but it isn't something that you needless need to pressure yourself with, if you understand your water parameters from your tap, or alternatively use RO/DI to create the right environment for your little fishy friends.
General Hardness and Carbonate Hardness are very confusing when you first start out in the hobby, and I hope that my videos will help simplify the chemistry that you will need to understand so that you can successfully keep your fish for many years.
If you have any questions, please feel free to leave a comment and I will get back to you.
Happy fish keeping!
GH/Water Hardness Table:
dGH (Degrees of General Hardness) | PPM (Parts Per Million)
0 - 4 dGH | 0-71 PPM = Very Soft
4 - 8 dGH | 71 - 142 PPM = Soft
8 - 12 dGH | 142 - 214 PPM = Moderately Hard
12 - 18 dGH | 214 - 321 PPM = Hard
18 - 20+ dGH | 321 - 357+ PPM = Very Hard
Typical GH levels for Aquarium Fish:
dGH (Degrees of General Hardness) | PPM (Parts Per Million)
Freshwater Aquarium: 4-12 dGH (71-214 PPM)
Discus or Planted Aquariums: 3-8 dGH (54-142 PPM)
African Cichlid Aquariums: 12-20 dGH (214-357 PPM)
Shrimp Aquariums: 4-8 dGH (71-142 PPM)
Typical KH levels for Aquarium Fish:
dKH (Degrees of Carbonate Hardness) | PPM (Parts Per Million)
Freshwater Aquarium: 4-10 dKH (71-178 PPM)
Discus or Planted Aquariums: 3-8 dKH (54-142 PPM)
African Cichlid Aquariums: 10-18 dKH (178-330 PPM)
Shrimp Aquariums: 3-6 dKH (53-107 PPM)
Saltwater Aquarium: 8-12 dKH (142-214 PPM)
Typical pH levels for Aquarium Fish:
Freshwater Aquarium: 6.5 - 7.5
Saltwater Aquarium: 8.0 - 8.4
If you want to keep fish that are not suited to your tap water, I recommend investing in an RO/DI (Reverse Osmosis de-ionised) unit and mixing the RO water to the right levels. I use two RO/DI units, made by Vyair and Osmotics UK, below are some links to their websites:
