Alk trying to go higher

[reefcoralclam]

I use to to use instant ocean but corals started to not look the best so I change to Red Sea coral pro and I have done multiple 4 gallon water changes in my 30 gallon alk is still at 7 help please.

7 dKH is fine and is not the cause of coral problems. I'd look elsewhere for the problem.

Hello,

Have you checked other parameters for the tank? Calc? Mag? maybe your calc is higher than alk. They work together when dosing. Are you possible dosing any type of supplements like Kent marine, Red Sea?

I’am not dosing anything and I have not checked calcium
