Just getting back into the hobby after 10 years away. Last time I had all MH (400w) on a SPS dominant tank. This time I’m going LED. New tank is a Red Sea 425xl - so dims are roughly 47 x 22 x 22 - and I want to do all SPS again. I’m new to LEDs and after reading a lot I’m still not sure if I should go with 2 Hydra 26’s (or maybe 3?) or just 2 Hydra 52’s?
