The only reason I was worried about the coraline algae growth was that I read that it's proliferation was a sign of a healthy tank. That and a couple of rocks had completely bleached out. I think my test kits must me coming from the moon (still no here). I left the MH
on for 7.5 hours today and I had algae growing on the glass that I know was not there this morning.
On another note. We got that rock today that I mentioned earlier and there were fleas all over them inside the bag. We were totally grossed out. Have you ever had that happen?
