My alkalinity is around 8.3 and calcium at 400. I have to dose both every 4-5 days to keep levels up. But my magnesium drops very fast. I tested 2 days ago and it was 1350. Today it was 1200. This seems to happen a lot. If I go more than a day or so dosing magnesium, it will drop like 100-150 ppm. Any reason for this?
I only have one small favia, a 2 headed hammer, 4 small zoas and a rhodactis.
