BRYOPSIS removal help!!

[BioMan]

I've had a small setup running holding my not favorite corals that I've collected over the past 4-5 years until my upgrade is ready and Ive noticed what is 100% BRYOPSIS!!!! I've never had this, but I do blame it on a zoa frag I bought off some guy, thats where I first saw it a month ago. Its spreading. My tank stats are as ideal as possible:
2 pieces of fully cured 4-5 yeard old live rock,
ZERO or close to it, near perfect everything. 25% water changes a week, carbon reactor and gfo reactor and filter floss
assorted corals, 2 clown fish and 1 anthias.
what eats this stuff?

Take the zoa frag into a cup with tank water. Pour some hydrogen peroxide in until the frag plug starts to bubble. Leave in for a few minutes and will kill it.

Also, get Kent tech M magnesium and slowly raise it. I raised mine up to about 1800 and that was the point where mine died off. I've heard that above 2000 is fine too, but for me 1800 was the level where it killed mine.
