Has anyone with a long-term "alkalinity rising with no dosing" identified their problem source and fixed it?
I'm at 8 months of alkalinity rising 0.2 dKH daily and just fighting it off with low alk water changes (using Sodium Bisulfate in new saltwater) every 3 days or so -- works but just inconvenient.
My specifics are that I have all soft corals so could just be due to nitrate consumption but I've also considered replacing my aragonite sand as last ditch effort (but that would be a chore and not confident that's the issue anyway).
*tested all potential sources I could think of (including sand), individually, in small surrogate tank over a couple of months and never found the culprit
