Why?? There's absolutely nothing wrong with 7.6. And, if you attempt to adjust it, especially chemically, you're far likely to do more harm than good. Chemically lowered pH almost always bounces back to what it was due to the buffers in the water. About the only stable
way to lower pH is to start blending your pwc
's with RO
water to lower the KH
. My well water's so hard, it's what I have to do. I blend 75% RO
to 25% tap to maintain my pH at 7.6.
I'd say leave well enough alone. As long as you're stable, the fish will adjust. Most LFS
's in my area use city water, and they run 7.8 to 8.4.
