Ostreopsis are USUALLY the easiest dino to defeat. In rare cases it takes some time. Most often it is because reefers don't deploy UV properly. The bulb is old. The flow is too fast. Not enough wattage. Ostreos have a protective SHELL called theca. Many reefers use UV to give them a suntan instead of destroying the shell.

I blow them off and an hour later brown is forming on them. I dose nitrates, phos, bacteria, and still they come. They are on every surface in the tank.

I am getting so tired of them. Even when you beat them they hide out in places like the green hair algae on the tanks walls. I found out when the cyano came the dinos were not really gone, they hid in the green hair algae on the back wall and side of the tank. It pays to a microscope. I never dreamed they were in the hair algae waiting for a weakness to come. I also feed my clams food. I can not change water forever, I have reef clams, and they have needs.
