Anyone have any suggestions for eliminating Dictyota in a nano reef. It looks like this:

and is growing like crazy. It's mostly on only one rock now, but it is starting to spread.

Help!!!

Some huge fish (like nasos) and maybe an urchin, but for a nano, I'm afraid manual removal is the best.

Yeah, remove the one rock and nuke it if possible.

An Emerald Mithrax Crab?

I have a Nano and was having blooms...one small one of these and he's got it under control.

I was also using water from the machines at publix since i don't have a RO/DI system at home and have since been getting water from Keen Reef and that seems to have helped a lot.

Yes, water at publix good.
