Had this crap come out from one rock. Started to pluck it out by hand and over time it has spread to every place in the tank. Bought a foxface and get doesn't eat it. Bought some nudibranches and they made a tiny dint to it, but they have all either died or god knows where they are. Any suggestion?
This is on a 360 SPS tank with 4x400 radiums, 100 gal sump, ca and kalk reactor and even UV. Heavy fish population that is heavily fed.

I recently had an outbreak of this that quickly spread from one or two rocks to multiple... in the order of a couple of weeks.

I have a Sailfin Tang that grazed on it some, but did not seem to make a large impact. It had grown to lenghts of 3" or so when I was about to the point of pulling the rocks to try and clean some off. It just all of a sudden disappeared. It looked like it had been clipped off at the base.... not sure what did this..... the sailfin, crabs or something else. Soon after it has receeded to where is is almost not noticible.

Along this time as was in the process of raising my calcium from the low 200's up into the 400s. I think when I got into the low 300's this stuff dropped off. Not sure if it was related or not in anyway.

My Ca is 450 and DKH is 12. Phosphates are not detectable. Everything else is book perfect.

Bryopsis is a drag. I had a patch start in some green star polyps and it got bad, but in just one spot. I ended covering it with some big seashells I had. It took quite a while, but I killed it back that way. The gsp recovered, amazingly.

some people have had lick using the crispata nudi's. in my case, i had a rabbitfish (not sure what kind) that plowed through bryopsis like no other.

There you go, I bet that's your problem!

You better have heavy nutrient export or your bryopsis will flourish like wild fire.
