Yes I like those and do take out any Caulerpa, except if it is in a Fuge ... it grows real fast and puts out those runners that can irritate corals and Zoas/Palys
Yeah, how to control it, I tried increasing Mg without success
I have to mow it every week
sally lightfoots and emerald carbs won't eat it
My Emerald does not eat it but bites on it with his claws and loosens pieces of it that then start floating around in the tank and eventually get caught in the filters. I have seen mine try to eat Bryopsis but he does not really eat it either, just picks at it.. Have just one little clump of it and it has not spread and when I take that rock out I am going to just remove it but the rock is at teh bottom so it is not easy to remove but I'll figure out a way : - )
