I am wondering if I have a problem? My calcium will stay about the same all the time 480. last week over the period of the week it dropped to 475. Alkalinity I had at 12dkh over the coasre of the week it dropped to 8. Is this normal to have alk being used up but not calcium? I am using Seachem Reef Builder for Alkalinity I am thinking of starting a 2 part system from Bulk Reef Supply but was kinda waiting till I started using calcium. Should I just go ahead and just add alkalinity and magnesium but not calcium? Just can't seem to get them to balance and drop together like i thought they were supposed to do. Maybe I am wrong?
