Agreed, leave the pH alone. pH altering chemicals do not work. They temporarily adjust the pH but eventually it starts a fluctuation. Fluctuating pH causes stress to the fish. If you want to naturally reduce the pH you can use peat moss, RO water, or tons of driftwood. But honestly, 7.6 isn't bad, I'd leave it as is.
A pH change of .6 isn't going to harm the fish. They tell you it must be 7.0 so they can refuse the return if they die. I had a pleco die once and the lfs refused to refund my money because the pH was 7.2 and they said it must be 7.0 for the fish to live. They just didn't want to refund my pleco.
I agree with Fishyfanatic.
Don't play with the pH unless you really have to. The fish do well if it's consistent. Better not to have it bounce up and down like a yo-yo.
Stores that have that return policy generally have lots of problems and need an "out" to stop a large volume of returns. They tell you we know what we are doing, it was your fault. I'm starting to doubt a store clerks ability to spell the word "fish" let alone care for them.
