Thanks guys. I turned off the lights for two days and the ha is almost all gone. Now Ive got a few other issues. What are the little white aafid things on the glass? Will a six line wrasse eat them? Also does anyone know what the little pink invertabrates are with the little white extentions that come out in the dark? When the lights come back on they retract and look like a little pink bump. I have a bunch that came on my LR. There is a glass anemone in my tank that just killed the crap out of one:/
