Wondering if anyone used Melaleuca products before? There is a formula using their tough and tender product to kill white powdery mildew, but not sure if its safe for the fish?
Probably want to be careful and not get it into your water supply. Melaluca (Tea Tree) Oil is a natural bactericide and fungicide. It would probably help with the mildew, perhaps even some infections with fish, but if it got into your water it might kill off all your beneficial bacteria.
