I have what I'm pretty sure is green cyano growing all over my rocks and sand bed in mats that is easily removed by blowing it off of the rock or pulling it out with tweezers. I've been dealing with this for about 2 months by manual removal and water changes, chalking up to a case of "the uglies" and assuming it would clear up eventually. My tank will look ok for a few days after maintenance but then it comes back quickly and just as bad. I don't have access to a microscope to positively ID, but is this green cyano, or something else? I'm open to any and all suggestions on reducing it down to a more manageable level so that it's not such an eyesore in my tank. I'm hesitant to even post any pictures of my tank until I can get this under control, that's how hard it is to look at. The tank is about 6 months old. Thanks in advance!
