Radion G5s for a 144g half circle?

[Aaarrrggg]

Finally time to upgrade from my Radion G1 to G5! :dance:

I currently have 2 Radion G1's and have mainly softies, nems and LPS. The tank is a half circle shape with dimensions 57.5 x 29 x 29. It has a plastic bar in the middle, so 2 lights are ideal. Could I get away with 2 XR15's or will I need 2 XR30's?

One of my current G1's has just died, so if you could let me know ASAP that would be awesome!!

 

[Aaarrrggg]

Realized I could just call tech support and get the answer. For anyone reading this:

Ideal: 3 XR15's

BUT because of the center bar on my tank: 2 XR30's
