So you guys still can't get RC?
Once it started to grow I would pull what I could out. Some would come out in mats easily but other areas like the sparse stuff in you pic was hard to grab. All of a sudden it seemed the faster I picked the faster it grew. Then it started to grow on some of my corals, I removed any coral or rock I could get at and used tweezers and or a toothbrush to clean the piece. I always have fed very lightly and knew excess nutrients were not the problem. It grew directly under the lights and in the shadows. I had lots of flow and fresh bulbs. I was lost because I couldn't find a pic anywhere and didn't know the name. None of my fish or crabs or tuxedo urchin would touch it. After alot of time on RC I finally found a pic of Dictyota and without a doubt that is what I had. Once I had the name, I quickly found out that a Naso or a Foxface very often, but not always will eat it. Some have success with emerald crabs, I had several and they did nothing for me. I remember a RC thread where a certain urchin might help but I can't remember what kind. I'll check it out and post if I can find it. My tuxedo didn't help at all. I finally went with a juv.naso 2-3" i kept him hungary in QT for the first couple of days then put a small rock with this stuff on it for him to eat which he did right away. When he was put in the display he continued eating the Dict with avengence. I continued getting what I could out manually and it wasn't long before I could see I was winning. It took 2-3 months. When I put the Naso in, about 75% of my total rock had some, of which 30%-40% was heavily covered. That fish saved my tank. It's been about 1 1/2 years since then and it hasn't come back. I sure hope RC is back for you guys soon. At least then you can check out some of it's threads or even post your pic.to determine if what you have is Dictyota or not. I hope it's not, but to me it really looks like it. Good luck
