Can anyone tell me what these green things are?

[RPatsula]

Thank you everyone for your suggestions. I was able to pull the piece of live rock out and remove the algae manually. It was interesting because I punctured one of the bulbs and it squirted all over my workbench, thank God I had it outside of the aquarium.

I searched through the message board to find the Radeon thread. I was able to come up with a different profile for my lights. I hope it stops the bubbles in the sand and the red algae growth. I think I will look through the lighting posts and see if there's more information on Radeon profiles.

I started into this hobby with very little experience with aquariums. I find that the CanReef message board is great for advice and suggestions. Now that I have figured out how to use photo bucket, I will post pictures of my build. My tank and stand is a work in progress but I am happy with it.

Once again thank you
Rick
