How many Radions

[ThatPhillyReefer]

I have a 90g 48”18”24 tank.
How many radion xr15 would i need to support a sps dominant tank
Or
How many radion xr30 would i need?

I would do 3-15's or 2 30's if radions are the choice.

More 15's for coverage...get 4 of them, thats like 2 30s but you can spread it where you want it.

I am setting up the exact tank, and while it may be overkill I went with 3-XR30 blue's to help with spread and will just dial the intensity to the required with a PAR Meter.
