I am adding several calcium additives to my 55 reef tank, namely seachem reef calcium, reef complete, reef plus, and reef builder. Im adding two caps of the liquids twice a week and 1 tablespoon of reef builder once a week. I cant get my overall calcium level over 8ppm, what should I do? Since I add these to my sump which my protein skimmer is working from, could the PS be removing the calcium before it gets into the tank?
