Is this an algae?

that middle pic looks like an aiptasia,others look like algae you sometimes get on new live rock

 

No, there are no bubbles in them. At least not that I can see.

 

Really? That sucks that it's an aiptasia! Them things you can't get rid of...

 

First and third pic look like the same growth. Perhaps macroalgae, I can't tell. The middle pic appears to be some sponge growth. If it's all the same color gray, it's probably just that.

If the finger-looking projections are striated (striped) it might be an aptasia. From what little I can see though, I don't think it's aptasia.

 

Okay, well I guess I will have to wait and see. lol Too much brown algae on everything right now any way. I have been trying to get rid of that. Again, I put too much live rock in at once and got a little spike in nitrates. Not too bad, but with the lights I have on my tank (till tomorrow) it made massive ugly algae grow.

 

Less light will keep algae from blooming. This will help. Go to the algae forum. There is a ton of info there. Since you can see yours from many angles, Lights and in 3D you can probably ID it pretty easily from the pics they have posted.

 

Will do. I am not too worried about the algae because I don't have any coral and only have 2 fish right now. I am planning on moving in the summer and don't want to buy new stuff and them end up dieing. So, I am trying like crazy to hold off buying anything. lol Thanks for all the suggestions!!
