Unfortunately I do not have a phosphate and calcium test kit, but I always bring a sample of water to the store and last week they tested everything and said it was goodSo what were your nitrates? Phosphates? Calcium? These parameters I have seen affect hermits the most. I personally don't like hermits, but that is just me. It could be copper, but I don't think it is. Maybe an ICP test would show some high metals maybe?
