Hi there people. Ive got a new tank being delivered next sunday and i already have clown loach ,ruby shark and a pleco in my current tank. I live in a hard water area so i assumed that i would be able to introduce new fish with ph levels of 7.5 to 8.5 into my new tank, the fish i currently have have a ph level up to 7.5. Ive been told that the high ph fish would settle into my new tank quite well due to the hard water in my area, but also been told that i would need to get rid of my current fish. I read up on a site this morning that you generally dont need to change ph levels as fish of similar tollerances will adapt. Help, what can i do please?
