I want to add Kribs to my community tank. I had my water tested at the LFS my levels are fine. my pH was at 7.2 the LFS employee said I would need to increase my pH if I were to add Kribs. the info i read on kribs says they are fine in a pH 6.8-8.0. So the store would not guarntee the fish with a reading of 7.2. I have been using ph increase to slowly get my ph up, but it doesn't seem to be increasing any. not sure what to do. If I were to buy the Kribs can they adjust to the Ph in my tank?
