Cool. Thanks guys. I think the red algas need more light than the green caulerpas in general, right? It sounds like this will be enough. I wasn't sure about the aquarium and plant light's 2700 K color temp being so low. It sounds like what blueboy's using successfully.

I can't wait to get this tank plumbed to my main tank. Once I get my fish room all up and running I'm going to try for Tank of the Month.
