Hello everyone! I have two 20 gallon tanks set up side by side. One of them is set up for shell dwelling cichlids (multis). It contains aragonite sand. The other tank is being cycled for GBRs and so I added a bunch of peat into the filter to soften the water and drop the pH. Both tanks contain nothing else besides a heater, a filter, and a few bait minnows. The tap water comes out hard but at around a pH of 7.3.
I expected the pH in the tank with aragonite sand would spike up and the bottom would drop out on the pH in the tank with peat.... but instead they're both around 7.4-7.6. What the heck? I've done several tests on both tanks using high range and regular range pH tests. What's going on here?
