Welcome to Reefland!
It could be a different species of coralline algae. Can you get a picture posted? That would help immensely.

Hi raycopp,
![]() Do a search here for cyanobacteria, I would almost bet this is what you are seeing. Can you easily blow it off the rock? |

No, i will not blow off the rock at all. It looks more like a sponge of some sort. Is this at all possible?

A sponge is possible. I happen to have one that is dark red. Does it have any sort of volume, or is it flush against the rock?

Yup it is possible it is a sponge or other type of coralline. It will be hard to say without a picture.

i think i have the same thing in my tank does it look like little clusters kinda look like small stalagtie? is it taking over your rock or just sporatic? the stuff in my tank is very sporatic i have a 100gal with 150 lbs of live rock and id say about 8-10 of them growing on it throughout the tank and a little bit larger then the size of bb for a pellit gun

Thank you for all the replies. It does have volume and yes it could be considered dark red. It is not taking over the tank. I have a 200 gal and maybe there are 20 or so
