Thanks. I guess I originally only had diatoms. I now have slimy sheets of brown algae that has air bubbles in it. It's over 15%-20% of my substrate. What can I do to fix this?? It just started to happen. My water tests show up fine. It's getting much worse.
I can't take pictures because I don't have a memory card
