Kessil light options for a Waterbox Marine X 90.3

[tomtle]

Hi! I just ordered a Waterbox Marine X 90.3 which measures 35.4" x 19.7" x 21.7" along with one Kessil AP9X. I plan to create an SPS dominated tank. Technically, the light fixture is rated to support this size tank but I've noticed that there are several people who decided that this single light alone wasn't enough for optimum SPS growth and color given everything else in their system is optimal. Is this a valid conclusion based on customer feedback and in house testing? If I wanted to add additional Kessil lighting, would it be better to go with one more AP9X and run them right next to eachother? Or perhaps add two A360X or A360XE on both sides of the AP9X?

I have the option of buying two used A360X or two new A360XE. Any suggestions and experiences with this proposed setup are appreciated!

Best,
Tom

I have the AP9X on my new 90.3, still cycling but it seems to cover the tank reasonably well. I'd give it a shot.

The AP9x will do just great for growth, but may be problematic as the SPS grows out and causes shading due to the spotlight design of the AP9x. I recommend adding bar or puck type fixtures for fill. below is a photo of my setup along with some recommended products for your consideration, I use an orphek or3 with a dimming smart outlet for app control:
