Hello, I have just started a new tank and am surprised to see the alkalinity drops about .5 dkh a day. It’s a IM 20 gallon tank, so about ~15 gallons of water volume with live rock and everything and I have been dosing 3ml Red Sea alkalinity every day to keep it stable. But I am surprised because I was under the impression I wouldn’t need to dose for the first few months. Any insight into why this might be happening or is it normal?
