Nice. I see one Radion pro, maybe there's two? If you are using one, will it be sufficient? Good looking tank.
What about building your own led/t-5 hybrid in a floating canopy using the radion? I'm going to attempt that. Hopefully when I get home there will e a package from BRS with my LET lighting t5 retrofit kit!
I thought you sold the radion?
I like the concept (two mountains in my tank too!) but I do have some suggestions.
It looks like it's against the back of the tank. This is a flow killer. You might try less rock to create a more open structure.
Making one mountain significantly smaller will give more visual interest. Our eyes love unbalanced/asymmetrical things.
Size and distance is hard to see from a picture. Try to visualize the rock with grown corals. Could you get to the glass to clean it?
Beautiful tank and stand, BTW.
