The pH of my tank stays around 7.8 - 8.0 because of the high pH city water. I chose to keep Rainbowfish because of they can handle a higher pH. Would it be worth it to try using things such as Peat Moss to try and lower my pH for the other fish in my aquarium (neon tetras and an albino bristlenose). I’ve heard that it’s better to have a consistent pH rather than risking a fluctuating one.
