I tested my water before I went to the LFS I got 6.8 but I took water with me and they tested it. the guy said my pH was a little high. He didn't tell me the number. I guess I should have asked. However I didn't think 6.8 was high. I want to get one angel and maybe 2 GBR and a honey Gourami or two. I only have six raspbora now. Should I try to lower my Ph.
