Nice! I like the separated rock like that. I have those same lights on my FOWLR. Was wondering how much your temp is increasing? Coincidentally I'm getting the same chiller, but for my MHs on my reef tank. I'm really hooked on the Arctica- how's it working for you? Didn't need a chiller for these lights though.
Looks really good! I like the suspended lights better than the legs.
