So I got a nuvo 40 from a friend to upgrade from a 10 gallon. I would like to get back into sps with an sps dominant tank. In the past I always had t5s over my sps tank and loved the growth but leds intrigue me. I have been trying to decide between gen4 xr30 and 6x24w ati. Can anyone with these lights or tank steer me in the right direction?
