So three days ago my tank had plenty of brownish algae - pretty sure it was cyano. The next day, there were copepods crawling all over the glass. The next day every square inch of my tank was clean and bright white except for a few strands of hair algae that I'm working on getting rid of. The next day, still clean and white but my water went cloudy. Everything is happy except the toadstool frag isn't fully extended. No ammonia spike. I'm wondering if I had a bacteria bloom but why'd the cyano literally disappear over night?
