My ph seems to be dropping rather quickly and I'm trying to understand what I can do.
It's a 65 gal tank with a nearly filled 15 gal sump. My tap ph is about 7.4, but it seems to drop to 6.4 and below after a couple of days. I have about 7 fish in the tank.
Recently I added a few pounds of tufa rock on the sump, but I haven't noticed any difference. Any recommendations or possible explanations?
