| Like some have said, I would have another calcium test kit and test for calcium it maybe that your test kit is bad. Also magnesium need to be three times as much as your calcium, so if you have 400 for cal then your mag needs to be 1200. This will help keep your alk and cal in ballance. Calcium reactors are not really for calcium they actually maintain alkalinity and in doing so they keep up the calcium as a by product.
