Wow thats some good info ill check it outMcdaphnia said:It is probably better to avoid trying chemicals to change the water since the fish are more affected by water quality, clean new partial water changes regularly. With Tanganyikans, if you add something, it can be cichlid salts. These are not the NaCl in your shaker but a variety of minerals attempting to replicate the chemical make up of Rift Lake water. It is important to b e consistent and accurate when treating water. Here is a direct link to one way to do this, from the library here. https://www.cichlid-forum.com/articles/ ... recipe.php There are also commercial mixes specific to the rift lakes. Tanganyikans grow better when they have a source of iodine, either in foods from ocean sources or from reef aquarium additives. A director of a public aquarium told me many years ago to use a reef aquarium iodide, not Lugol's, at the dose for a reef tank. Not so important for adult fish, but it prevents some common maladies that are related to thyroid like deficiencies.
