is this ok for my coral?

sorry wasn’t quite sure what category this would fall under but i basically just installed a HOB fuge running a reverse light cycle but the thing is the chaeto light bleeds through as much as i try covering it. was wondering if it’s bad to not allow some of the coral affected in that area to have complete darkness? (mushroom fingered leathers acclimating zoas and cabbage) it isn’t a direct beam of light, it’s basically diffused into the tank so it’s a little soft. i do notice some even react to the light and open up a little which is why i worry they aren’t getting enough down time or something..

overall question i guess would be do coral need complete pitch black darkness for x amount of time?

It is not necessary for corals to have complete darkness. People often run moon lights on their tank at night which does give some light to the tank. I honestly would worry more about the fuge light fueling algae growth in the tank more.

Obviously, if there is a way to block that light off more than you already have, do it. But if that is the best you can do I don't think it is going to harm those corals.
