Have been adjusting the dosers for Alk and Cal over the past two weeks....when I ran a two day test, Cal only dropped 1 ppm so didn't turn it on...only Alk....have noticed a few acans not looking happy and a few losing tissue...looks like Cal went down from 447 to 387. Used BRS calculator and added enough to get it back to 425...will be checking it again in the next 48 hrs. All other parameters look fine.
