    hey reefers, having some problems with cyanobacteria. Its growing like crazy in my tank. I have reduced lighting to seven hours, only ro/do water, and reduced feeding to every other day. I brush it off the rock about everyday with a toothbrush and siphon it off the sand with weekly water changes but it continues to grow like crazy everyday. I feed mysis only. considering a phosban reactor. any suggestions would be appreciated.

    Thanks

    happy reefing

    Do you test for phosphates?Cyano is a result of excess nutrients,so you're on the right track to fix it,i've also found a good cuc and increased flow helps quite a bit as well.

    Edit-adding gfo can really help in lowering phosphate levels also.

    i was told gfo has adverse effects on clams, which i have a few and would like to get more. I currently do not test for phosphates. I have to 1050 gph powerheads in my 55 and was considering 2 more little guys to help

    Yeah,adding another one or 2 would help take care of any "dead spots" and improve overall flow.But i haven't heard that about gfo and clams,maybe someone with some clam experience will chime in on this.

    how old are your lights?
    and how big is your tank?
    how much do you feed?
    :)
