What are ways to bring up my ph to a more neutral ph level. I did another test in my new tank and it's at a 6, tire track does not seem happy, I've done a water change already. I used vinager to get off hard water stains, when my tire track had jumped out of the tank I had thought maybe this was the issue but the ph test was higher more towards a 7 (like a 6.6 6.7) when I tested it, how can this be (that it would become more acidic) after water changes. My test kit is less than a year old. I just tested my tap incase something weird had changed and its testing neutral. Any suggestions to up the ph before the stores open?
Thanks
