    Can I convert cyano to algae?

    I have a tank with consistently high nutrients. It’s not neglected but I do minimal maintenance and for the last while there has been mild amount of cyano persisting around the tank.

    Thunder Goose Declares WAR on ALGAE - Two Month Update

    I haven't been thrilled with my tank for a while. My corals don't seem to grow, just limp along for 4-6 months then die. So I decided they weren't getting enough of something. Tried using BRS 2-part. Nope. Tried allowing nutrients in the tank to rise and... guess what? The corals are STILL...

    Tank down the tubes in a few days. Cyano, dead inverts, coral closed. What did I do?

    For the past few days, my zoanthids have been all closed up, my leathers have shrunk up, and I have been getting more and more cyano (presumably) over the past few days. My crabs and snails have mostly stopped moving over the past week (but the shrimp are fine). I am trying to narrow down what...
