I'm telling you bud, from one long time reefkeeper to another. Use chemiclean. I fought for ages after the whole bobit worm take-down to fix my tank. Only chemiclean helped. Ill never, ever hesitate to use it. I tried starving my fish, black outs, 20% water changes siphoning out the slime every 2-3 days for a month, the Zoevit cyanno stuff, bacteria dosing. I even vacuumed my sandbed into a stack of 7 filtersocks every day for 2-3 weeks.
PS: I ran two air pumps feeding under my mp40s and ran my skimmer full boar during the treatment.
