I just stared using ati essentials. My tank is 150 gallons of water or 567 liters. It is heavy sps. I have some large colonies. My starting dose was 50 x 5.7 = 285 mls. On day one my alk was 7.45 dkh. Day 2 alk was 8.79. I lowered the dose to 80mls based on the formula in the manuel. Day 3 alk is 8.79. Should lower it some more if so how much do you suggest or should I turn off the doser till alk falls back to near 7.5. 7.5 is where I would like the alk.
