The stuff sucks! I had it in my 40g tank and it grew over and killed some really nice micros. I found that nothing really ate it, just some additional maintenance and it literally just disappeared. I added GFO and it really died back quickly. Hope that helps.
I hear naso tangs will eat it but i had a hard time getting any at the LFS to eat them. I did weekly water changes and it slowly died off. I manually removed it when it started to plate instead of encrust. hope that helps...those things are a pain.
