I had to use the Red slime treatment myself, Chemiclean. Blow it off constantly helps, don't let it build up on corals. My nutients went up to 25ppm nitrates and 0.159 phos and so far just a trace of cyano. My rock is covered in coraline now after treating for GHA and cyano.I have a ton of cyano building up on my sand bed and my corals. What can I do to combat this problem along with the Dino's I am still fighting. Cyano builds up on my corals everyday....
