I just bought a doser and would like to now a good starting point for all 3 (alk, cal,mag) I currently have it set for 20ml a day of each. Its a 90 gallon reef. been manually dosing and its kind of all over the place to keep the perimeters in check. seems to be getting close to the 25 ml day range. not many corals yet but will be adding some soon but do I let it ride a week then test or test everyday and make adjustments
