fishdude Posted December 10, 2022 Share Posted December 10, 2022 These little patches started popping up recently. Not sure what it is. It’s only on my rock work. Did water tests and everything’s good. Nitrites a bit higher than I like but easy fix. Fish and corals all open and healthy. If anyone knows what this is let me know! Tanks only about 5 months old.

cjmdh Posted December 11, 2022 Share Posted December 11, 2022 Looks more leafy than slimy like cyano. Maybe this stuff or something similar? https://www.reeflex.net/tiere/3525_Halymenia_floresii.htm Quote Link to comment Share on other sites More sharing options...
titus'reef Posted December 11, 2022 Share Posted December 11, 2022 I would dose phytoplankton and copopods to help fight the cyano. trying to kill it with the chemiclean could invite Dinos. Quote Link to comment Share on other sites More sharing options...
