Just a bit of cyano...

Sorry, what I meant by bio-diversity was not to add more fish. That would compound the problem to some extent. I was referring to a clean-up crew including different types of crabs, snails, maybe a nudibranch or two, urchins...the list goes on and on. I would not, however, lose any sleep over your current situation. It is, as many would agree, a natural phase that you will patiently wait out, right? Don't give up. Don't be compelled to go out and spend lots of money to fight the problem either. Do you intend to eventually build a reef in your tank? If so, I would look into a ro/di setup. Ever since I got mine (Aquasafe Systems $160 shipped with TDS meter) my algae problem went away. I think that excess phosphates from the food that I was adding as well as the tap water was enough to sustain an algae paradise. Has anyone out there had much luck with phosphate sponge? That might be a low cost supplement to get you through the next few months. Rich.
