Thanks! I’m afraid of emeralds going after my coral but a Nudibranch is a great idea. I’m hoping the uv helps with any spores released into the water column. I do manual removal of the bubble algae and some always pop no matter how careful I am. Same with treating aptasis with aptasia x. They get irritated and I see new babies after treatment. I know the uv won’t do anything with stuff on surfaces, just the water column. Thanks for your help!Looks good.
I don't think it does much for bubble algae and aptasia.
Bubble algae --> Emerald Crab, Aptasia --> Berghia Nudibranch
