I've tested my water tonight in all of my tanks just curious about the "PH Rise" potential of these Masonry balls & cakes. It's been 3 weeks for one of the tanks, 2 weeks for the other two and I honestly can't detect ANY rise in the PH even in the smallest tank (only 6g before Sand & rock). I have to say that I don't see effect at all on PH with a reef ball. It just gets better and better
