My PH in my FRESHWATER tank is around 7.5. I have Cardinal Tetras so I want to reduce the ph to about 6.
JMHO, but I would leave pH alone. Once you start tinkering with pH, you also alter the alkalinity of the water. If you aren't paying attention to the alk while lowering the pH, you could really upset the balance and get large daily pH swings. IME, tetras don't mind a pH of 7.5.
