Can anyone tell me what these green things are?

I think I can take that one piece of live rock out and scrape the bubble algae off.
My radions are at full intensity using the natural lighting pattern. I never know what type of custom pattern to create. Waynemah, do you have radions as well if so what intensity are you using? I'll think I'll turn mine down to 80%.

thanks

I had mine turned down to 40% and slowly had them up to about 65 now and it grows everything really well. 80% may still be too high.

Here is my lighting and live rock placement so far. the picture isn't the best. I'll turn the lighting intensity down quite a bit.
