After adding a few SPS corals to my tank I noticed my Alk starting to drop, it took about a week to go from 10dkh to 7dkh. I didnt want it to drop below 7 so I bought a 2 part solution.
I add it it the morning and my Alk rises to 8, the next morning its back down to 7. Is that normal to drop 1 dkh in a 24 hour period
