Alkalinity 25..need help..

Is anything apparently suffering from the high alk?

I'd probably just wait for it to drop while dosing nothing, unless you find calcium gets too low, but water changes or adding a mineral acid (such as muriatic acid) can be used. The mineral acid approach drops pH tremendously, if temporarily.

Did a 20% wc and stopped adding alk for sm days and all was normal.
