I was thinking of keeping community fish like livebearers, tetras and harlequin rasboras
I just use tap water and I just use a de-chlorinatorFrom what I know these are all pretty hardy fish. Do you use the same water as your LFS does or
Does your water come from a well?

I'm not sure if we are using the same water or not... =[I think as long as your tap water is from the same source as LFS's is, then chances are the fish are already used to the pH of the water.
