I have a FOWLR set-up (46gal). My PH is 7.9. What is the best additive to use to raise and stabilize the PH. Just did a water change and saw no difference. Any ideas much appre.
A pH of 7.9 is not a problem at all. IMO the constant up and down jump from additives is stressful to animal life. That said, kalk is a good way to keep your calcium and alk levels in check and will boost your pH. If you are using another method for calcium I would leave your pH alone.
