I know slime algae, cyano, is usually deep red or black/green, but I have read that it can be green as well. I have used red slime remover in my tank successfully, but it will make your skimmer go nuts for a few days. I have used it after I did a water change and sucked out as much of it as possible first. Added the red slime remover and turned off the skimmer. After 2-3 days I did another water change and turned the skimmer back on.
If it is dino's, the lights off technique works, but stresses the corals. Turn your lights off for 3 days..make sure there is no sunlight or ambient light from the room that gets in. cover the glass if needed. After 3 days, start with the actinics for a few hours the first day and SLOWLY add more lighting hours until you are back up to your normal schedule. I did this in the past, it worked, but I turned lights on too quickly and bleached a few sps
. good luck!
BTW...what are these called?
I tried the lights out twice it puts a dent but does not eliminate the problem. May be I need to give it one more attempt. Those zoas are called chronos might.
