Need some advice….My mag has been sitting around 1250 forever and I’m trying to bump it up around 1330-1350. I am running a calcium reactor and everything is stable just not where I want my alk. I started doing Brightwell Magnesium-P and followed the directions for the ratio. I have dosed over a gallon and a half of solution and mag has not really moved. Is this normal to dose this much to raise alk?
