My 46g and 20g have both been taken over. It grows on everything including the glass, inside of my drains, and on my power heads. It's choking out some of my corals so I've been trying to manually remove it. It's so hard to get off the rocks that I've been pulling the whole rocks out and picking it off with my fingers or tweezers.
When I had just a little I actually liked it and let it be, now it's a big problem.
