I've not seen any coolia strand up in our tank, so hopefully you won't either!! I just find individual, moving cells, like in your video. Fingers crossed for you that you'll be able to begin to enjoy your tank again!Yes I was looking at the video and pictures of coolia and it definitively looks like that and moves like that If they dont stress my corals I could definitively live with them. I will continue to use vibrant and peroxide and hope it will stay this way. Thank you very much for your help!
