I have a small problem with some black slime type algea on my live rock in my FOWLR tank. If I take out the rock, scrub it with a toothbrush under some RO/DI water, will it hurt/kill the rock, or would this be ok? Any other suggetions. :notsure:

I don't think so but...I probably didn't explain it that well. It's on my sand bed in small sheets. It got on a lot of my LR. It is kind of slimy but it's definitely black and comes right off on the less porous rock in a sheet or soft flake.

It's hard to tell but if you rub your finger over that black patch in the picture, it comes off easily and the corraline is very bright. Sorry, I'm not the greatest photographer. Can you tell with this pic?

Thats not black. Thats cyno. What kind of flow do you have in there? usually happens in low flow areas. Picture does change things!!

Ahhh....thanks guys. I have never had to deal with this. Live and learn. So, you think I have a flow problem? I have a 92 corner with a Hagen 802 powerhead on one side up top. Should I maybe put a PH back in the corner behind the rocks on the bottom, or what do you think the best way to go would be? Appreciate the knowledge.
