Radion xr30 gen3 or 2 xr15 gen 3
 

Hi, I am looking for some help, would you go for 2 x XR15 GEN 3 or 1 x XR30 on a 3ft tank.

one xr15 either side of the tank or xr30 centre of the tank, which would be better for spread etc.

Tank Dimensions;

Length 900
Width 500
Height 600

I would probably go with 2 of the XR15's for a better light spread.
I do know people who have nice tanks with a single XR30 over a 3ft. tank.
