Aquarium Water Chemistry
As fish keepers, we are told that it is important to measure the pH, kH and gH of our aquariums and source water. Fish suitability is commonly defined in terms of the pH and gH of their natural habitat. Many aquarists, even though they measure these parameters, don't;t completely understand them, know how they can interact, or the affect they may have on fish. The purpose of this article is to try and provide some definition and clarity to the terms, determine how they interact as well as their affects upon tropical fish.
