dtd87,
sorry to hear that..fwiw, bryopsis is one of the hardest algae to get rid of (i know i know, you already know that)
need to find the source of nutrients that is feeding this algae. RO unit, filters, membranes, not enough flow in the tank are causes..
you might want to run your skimmer a little wet until the algae is under control.
when I had this algae 3 yrs ago, I did alot of reading on the subject. there is a high rate of failure and most ppl give up and break down the tank and start over..the only reason I mention this is this is how hard it is to get rid of it..
be patience, stubborn, and fight hard as hell is the motto you need to get rid of this stuff.
It CAN be done. I did it as I wasn't gonna to let the algae win.
