[65G, 36"Wx18"Dx26"H] Will two XR15G5's be enough for SPS?

[Phyber]

I have a mature MarineLand CornerFlo 65G tank, (36"W x 18"D x 26"H) that is currently running an AquaticLife T5 hybrid (four ATI Blue+) and two AI Prime HD's. I have a healthy mixture of acropora, monti, large derasa clam, and others.

If I swapped it all out for two XR15G5's, would that be enough to match, and better yet improve, on my growth and health?

I realize that my current AI Prime's are really just serving as filler color and shimmer...

Do you have SPS in each corner of this tank, or is it within a 24" x 12" rectangle. If so yes it will be fine. I have 3 on a 120 gallon. (48x24x25" tall)

SPS are mostly at the top of the rock structure, about the middle of the tank vertically and horizontally.

Two will work

I’d stick with what you have. You’ll probably want to add supplemental lights to the xr15’s. Just opening a can of worms. Very expensive worms. This being said I’m running 2 xr30 gen 4’s with 1 or3 daylight and 1 or3 blue light bar on my 120 gallon tank
