White Peach Fuzz covering rocks


Premium Member
I went on vacation for a couple of weeks back in April. When I came back I noticed a fuzzy film covering all of my live rock. It traps detritus and is annoying me. Anyone have any idea what it is? It only seems to grow where the light hits.

Here is a photo I took and you can kind of see it as a halo around the Live Rock. I'll try and get a closer shot of it when I get home.


Actually you can kind of see it better in this photo here on the bottom left and right rock:
