When doing water changes when cycling with fish what percentage of the water should i change at a time? I'm doing 1/3 change a day, but have read that I should do less so that the bacteria have enough ammonia to work with. What level of ammonia should I stay below? It's currently 0.5ppm. Also, is it true that if the pH is below 7 then the ammonia is not as lethal to the fish as it is if it's above 7?
