how much time do you leave between dosing calcium and alkalinity? You cant dose both at once.

Yes its into high flow, it goes though two sump chambers, then though a pump before hitting the DT. Dosing is done using the first two heads of a four head profilux. So I would guess between 15-30 mins between doses. As I've said before the paras were stable until august & @ that point I was dosing almost 4ml per gallon, which caused precip & the salinity to rise weekly while not maintaining CA levels. I can't figure it out unless the ca & mg tests are both pos. Or the ca supp. Is weak?
