What is an ideal range for Alkalinity in a Fish Only tank (dKH or ppm KH)? Does the range vary from species say, angels to triggers? What is the best way to lower the Alkalinity?
11 DKH is actually not harmful to the tank as long as the Ca is in balance against it. Alkalinity can be as high as 4.5-5 mEq/l (12-13 DKH) without much stress to the inhabitants. There is no reason to bring the levels that high artificially though. You might consider testing a newly prepared batch of salt. IME, that's where your problem will lie if any, especially if using IO salts.robocop said:Ok...how do I lower the AKL? Say I have a 30gal FO with a 11dkh AKL
