So my tank has been growing this nasty "bushy" brownish stingy algae for the past week and it has gotten worse and worse. Now all of my zoas are closed up. Any suggestions?
looks like dino's to me ( dinoflagellates...spelling?) i used hydrogen peroxide and it was gone in a week. Do your research on treatments for dino's if it is them. I'm sure someone else will chime in. Good luck. Sand looks like dino's other or all could be diatom's..
