My water is on the order of 1200 ppm. It's very very hard. I don't bother
with pH or hardness and I don't have a test kit. I ignored pH and
hardness when I was a kid and had soft water I ignored it in
LA when I had hard water and I ignore it now with liquid rock.

Unless you're trying to breed Apostogrammas or something you
can safely ignore it. 

Does the discus buffer contain any phosphate?
