Hello! I'm considering buying a used gen4 xr30 pro with diffuser for use on a tank with a 24"x 16" footprint. I'd like the ability to use the same light on a deeper cube tank in the future. The goal is to keep sps.
What do we think?
Another option is a used hydra 32, but the price is about the same.
