OK so what is the supposed benefit of Purple Up? I have been using it since I started my tank 2 months ago, primarily to encourage coraline alagae. I am using Kent salt and my clacium is regularly testing at 500 although my Mg is low.
Is there any benefit to Purple Up at that level of calcium? It tests at that same level with a fresh batch of SW as it prepares for a water change.
