Dave,
You sir have a good eye. It is the coralife rated for 65gals. I had a bad scare with it the other day. I fired it up to test it and the bubble size and production was horrible... it wasn't until I tried everything else that I realized that it might have been caused by the fact that I was testing it on freshwater instead of salt

Josh,
Thanks for the heads up - I think if I was getting a submersible pump though, I would need something in the 300gph range.
Cheers,
