Hi guys, I'm wondering if I should start dosing alkalinity because it has dropped from 8dkh to 7 dkh in 2 days. I only have 2 clowns in my tank right now, no coral or any other livestock. I am worried though because I just ordered a nice hammer and some xenia. Should I start dosing? And how do I start if so? it seems my water changes can't keep up with the alk being consumed. Also why would it drop since I don't have anything in there?
