X18 with Hydra 26

[MAXreefer]

Getting a peninsula Waterbox (72 x 24 x 25).
Mixed reef with minimal aquascaping. SPS will go more to the middle of the tank.
I am considering the X18 61" 4bulb. Would 3 hydra26 be enough or should I aim for 4?
Thanks for any help

I'm using 4 hydra 26 on my x18 on 60 inch tank. Mainly because I only use the t5 for 5 hours a day

I would suspect that you would be fine with the 3 based on the placement of the SPS in the middle. If you were full left to right with SPS, it might be a concern. The good thing is you can always add an additional 26 later if you felt you needed more coverage. The LED bracket for 4 sets are included.
