I'll do some research on that. I was contemplating an H2O2 dip.I don't think a CUC will take care of the frags. What I would do is first thing in the morning if there is algae on the plugs I would pull the plugs out clean the algae off and just put a little hydrogen peroxide on the plug but not the coral. I did this in the past but forgot how it went. If you do this then they will get a full day of light.
I hadn't thought about that. So just hold them out of water and drop the H2O2 on the plug? How long do I let it sit on their? Can I keep the frag out of water to do this?I think it would be better to use a pipette and just apply the H2O2 to the plugs so you can avoid touching the corals.
Yes take frag out of water, get a cup of tank water. Put the H2O2 on the plug, I am unsure the amount of time maybe 30 seconds and rinse off in cup of tank water. This may or may not work, I really forget. That is just one of the many methods I guess.I hadn't thought about that. So just hold them out of water and drop the H2O2 on the plug?

This is the cartridge you will use for this canister,Sorry, been out all day enjoying this 116 degree weather. Will post pictures when I find them. I have two types, this one is my favorite. It prevents detritus from falling off or out of filter. They have a smaller one but this one you can see inside the canister. You do not need to leave this in the tank, take it out when you are finished.
