Yea, clean them often. I run tunnel 6105’s and every 3 weeks I spray them with hydrogen peroxide from a spray bottle and scrub with a stiff brush.
I have found this stuff works exceptionally well on bryopsis but I have a big emerald crab living in a large patch of it and what will he eat when all the bryopsis is gone? Small fish!
besides, the bryopsis keeps my bubble algae at bay.

I've got that in the reef cupboard, just need to pull the trigger. Every time I'm about to dump it in I get some signs of stn and hold off.
Mine looks similar to my 250w radium pics just much more florescent under my all blue strips. Looking forward to the picture
