Red Dots on new Rock

I have just my live rock in yesterday, filled with life, from snails, crabs, feather dusters, barnacles and more. I noticed these red dots started popping up all over the tank and was wondering if you guys could ID it for me. I have circled the dots in my photo, promised to buy a camarea to take better photos.

Sorry, I don't see any red dots or circles in that pic. It may just be some coralline algae

I think I see what you're talking about. I'm guessing it's either red algae or coralline. Touch it. Is it soft and spongy, slimy or hard?

Hello Biff,
Doesn't take a while for coraline algea to grow? It wasnt there yesterday and bam 24hrs later it's popping all over my live rocks.

It does take a while for coralline to grow. If it's soft and squishy, then it's a nuisance algae.

Time to to start cleaning it sounds like.

Could be red turf algae.It seems to grow pretty cotton pickin quick.

Maybe it was already on the rock (hence live rock) and is coloring up under your lights. My guess it's coralline. I would take a wait and see attitude.
