I stopped dosing. Started getting some brown, slimy hair algae popping up. I stopped using it about 3-4 days ago and the algae is dissipating.
Guess I am one of the unlucky ones that it use has bad side effect with. I really didn't notice any difference in the zoanthids, but only used it for a week. The algae was too much a negative to continue its use. Started growing on everything, whether there was strong flow or not.
Mike, you just keep on doing what you been doing all along. Your stuff has allways looked awesome before.
