hello, ??? I'm new to fishkeeping, and I decided to by a tank after have sucess with my betta, which is still alive of course. I was reading about pH, and I was wondering, should I just buy fish that are suitable for the pH, or use onw of the pH reducing powders. Is it safe to use those powders? Anyways live in L.A and I tested my water which has given me a pH of 7.8
