So I think I have to do some type of blackout for about 3-5 days. I think I have bryopsis or Dino but I’m not sure. I wanted to do a blackout with dosing of hydrogen peroxide. Will a long blackout hurt my fish or corals? I have two longfin clownfish, two filefish, and a scissortail dartfish. Will the blackout do anything to these fish? What about corals and anemones. Since anemones need light, will a blackout hurt mine? I have a green bubble tip anemone. How long should I do it for and do I need to dose hydrogen peroxide everyday?
