In an effort to find middle ground between Radion PRO and BLUE spectrum for SPS dominate tank, I'm thinking about a PRO - BLUE - PRO combo evenly spaced using the RMS arms (3 x XR15s on 36" tank). Would the blue in the middle be too noticeable of a difference? Anyone doing this on a similar sized setup? Would diffusers help with the blending? Thanks for any feedback.
