Reduce lights for 3 days, Harvest what you can and get it out of the tank. Red bugs gone? Did this cause your bloom? Find cause of symptom if you can, otherwise, deal with it. Check light bulbs for age? I dunno, what else sounds good? Up on water changes? Got some GFO going? 1st time with algae bloom? Got pics? Shoot some video. Play some rock n' roll.
