    I'll attach some pics at the bottom. What is this algae? I took the pics at night after the lights were out so they wouldn't look so blue. I've changes my water source a week ago and started feeding less to try to keep nutrients down. I have a bag of phosban between baffles in the sump and I have a small ball of chaeto in the fuge area of the sump as well. I have a CUC that I got from you several months ago: nerites, small and large ceriths, about 8-10 hermits, and several nasarius. The dark green stuff on the sand has retreated some on one side of the tank but is still going strong in the lower flow areas. The stuff on the rocks has just gotten this way in the last couple weeks. What can I do?

    Sorry Beast but I have to disagree. I see 3reefers responding to a wide variety of issues with great advice. I'm sorry you've felt that way....:(

    Yup looks like green cyano, syphon as much as you can during water changes, reduce your phosphates (which you're doing with the phosban), increase your flow in those areas

    With patience and perseverance you will get rid of it

    All those ways will help fight it, and I think everyone here is right, it is definitely green cyano. Good luck with the removal, if siphoning be agressive, get every last bit, every time for best results.
