Brown fuzzy Algae?

[Gfuller]

Please help if you can... It's not a huge deal right now but I want to be able to control it and make sure it doesn't get out of control.

It looks like it could be some sort of sponge, but not completely sure. It's brown, kind of fuzzy and is growing on a rock. I tried getting a good picture but they all suck

Kind of looks like natural progression of dry rock. How old is the tank and what's your parameters?

The tank is relatively new at 7 months old. PH 8.0 Cal. 420
Phosphate.25
Nitrate 5.0
Sal. 1.022

That is always consistent and everything seems to be doing great.

It very well could be natural progression of dry rock.. but I just wanted to have another opinion.

I finally ordered one of the lenses for pictures... This is a better picture of what I'm seeing grow. Does anyone know what this is?
