Can anyone tell me what these green things are?

Thanks for the information on the bubble algae. I'm new to the saltwater hobby so please excuss me if I do not know what type of coral I purchased. So the pink one is a brain coral I think.
My tank setup is as follows. It has been up and running for about 8 months. It is 230 gallons. The lighting is 4 radions with 2 mp40's and 2 mp10's. The sump is approximatly 100 gallons. I do about a 35 gallon water change every week. Do you need any other information.

Thanks for your help
Rick
