Well, I've had a terrible outbreak of hair algae, diatoms, bryopsis, you name it I have it in my new frag tank. It cleaned out the main tank though... lol. Is there any way to control it without getting a phosphate reactor, refugium, or anything else that costs a lot? How should I control it. I can't siphon it out -- it is everywhere and strongly attached. Way to much to pull out too.:doh:
