where is the pump? are you dosing and are you dosing close to the pump, and how are you dosing.
if you are dosing once a day in the sump and you pump is in the sump you are going to create a enviorment where persipatation of the ca is possible and the pump is a great place for it to happen, this can be compounded by a low Mg.
