Hi guys so as you can see from the picture i have a cyano problem but under the rock its not growing? Does this mean my lights are to powerful setting? I have a 100L that is light by 1 Ai 16 Hd all blues at around 80% and 9% white 3% red and green. I have a wave maker that is capable for 200L but as i thought flo might of been an issue added another one last week. Any help is very much appreciated
