Hi guys I have been struggling with what I think is cyano for over a year now. A little bit of cyano doesn't bother me but lately it has started to cover my whole sandbed and creep onto the rocks. I am unsure whether I am nutrient deficient or have too many nutrients. Nitrates and phosphates are both reading 0. My tank is decently stocked and I feed quite well. I have specifications on what I feed, stocking, photos and my filtration down below. I just want to get some advise on how to knock back this cyano some. Any input would be appreciated.
