How many XR30 g3's

Hello -

How many Xr30s would you put over a 63″ x 23″ x 24″H? Technically, I have a mixed reef but it is predominately full of large SPS colonies. Thanks!

May,

Since you keep mostly SPS is your aquarium I would recommend 2 XR30w G3 Pro Radions or 3 XR15w G3 Pro. Personally, I feel the 3 XR15w would provide better coverage for an aquarium that size.

Thanks, Alex. I currently have 4 Kessil a360 we and I feel that there is quite a bit of shading. Can you explain the difference between the Kessil and the XR15? Thanks!
