Question

Would 4 xr30w G4 pro units be able to cover a 4'x4'x2' sps dominant tank without need for supplemental light to address shadowing?

I would think so since they say they will cover an area of 36x36. I have 2x XR30W G3 pro and 1x XR15W G3 Pro over a 36x24x20 tank with little to no shadowing. The new lenses are suppose to have better spread. I wish they made them for the G3s.:(

Following . I have a 45g cube 24"x24" about to set up. Can One G3 cover this tank for sps dominant or need 2 of them? Thank you.
