JimD,

Thanks for the link. I stashed that one away. Wow, I thought we got into some heated debates around here. That's a heated debates with some heavy weights like Bornemann thrown into the mix.

I guess the question comes down to whether 420 nm light is required for coral growth or aesthetics. The answer from what I read is both, but its not necessary. On the other hand, if it was only about growth we'd all be running Iwasaki 65K.

Tim, I stand corrected.
