So the brown stuff (looks like diatoms) on my sand and little patches of cyano on my rocks have sprung up about 3 weeks ago and have gotten progressively worse. Phophates were tested with the Hanna yesterday: .02
all other levels are normal. i did a 36 hour "lights out" which had no effect. The tank was set up in January of this year putting the bulbs at about 10 months. They are not overdriven and are ran for about 11 hours a day. Seems like it would be on the early end of the spectrum to replace the bulbs, but not really sure what else it could be that's causing the algae?
