Not affiliated with the company just so excited with the results figured I would share my experience. Had a small outbreak of Bryopsis on a rock island and wanted to take care of it immediately. So I read up on this and read all the Fluc threads and figured I would give it a try. Followed directions and they say 14 days however all the Bryopsis was gone after 7 days. Used 9 of 10 pills for 180-200g as they say 20g per pill. Over the moon with the results. Also no ill effects at all on fish or my SPS. So if you are thinking about it don't be afraid just follow directions and win the battle.
