I lowered the time on my algea turf scubber to raise phosphates and nitrates. Then the hair algea took over. I tried algea fix!!!! It killed all my snails and my pencil urchin . So far I have lost my birds nest ,montipora and my pulsating exenia looks bad ,frogspawn might make it I don't know. My water peramiters are all good . But my skimmer is working overtime and I am changing charcoal every week. My algea turf scrubber is making clear snot yellow algea and green algea. I have turned the time back up on my scrubber fish look healthy so far missing 1 blue green chromis. But, they are 6 years old now. Sorry I have not been on here to try to help people but I have been busy!
