Can anyone tell me what these green things are?

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.

I believe 80% is a lot for radions. There was a good radion setup thread going around that could help you out. Sorry I don't have a link at this time.
