Coral metabolism vs. light par

[Canadian]

Steve,

Fauna Marin isn't equivalent to GHL Profilux - they just happen to be distributed by the same North American distributor (Aqua Digital). So you can criticize Fauna all you want without criticizing GHL.

And I agree about the pics being an add but they were the only ones I knew of off the top of my head that included underwater and out of water pictures of SPS grown under T5s.
