I got an accurate pH test and found out that my pH was 7.6 This got me thinking, I was aiming for a pH of 7.0 but is this best for me fish and future fish. I have an African Pike, leporinus, 2 plecos, an upside down catfish and a Lion's Cove. I am planning on getting a Raphael catfish, bristlenose pleco and some other fish. Most would be from african or the amazon What is a good pH that I could maintain that all fish could be happy in? And what is the best chemical for maintaining this pH.
