So will the regular XR30s grow corals? R is it that no one have them they just forked out $$$$ 4 the PROs
What coral are you thinking about keeping? The xr30 gen whatever will grow and keep coral alive, all types. Find old threads and people have been having success since they came out, and not just with radion but with early kessils, AI sols ect, chinese led boxes.
When you get into the newer xr30s and pros, hydra 52 hds, kessil ap700 price point you are paying for control- spectrum & output -spread of par/pur). These lights are geared more towards sps/mixed reefs, not just keeping them alive and growing but trying to provide the best overall spectrum of light to pull every last bit of color, growth/health out of sps corals.
I'm looking forward to seeing if people still need to supplement the g4pros with t5 lighting to get all they can out of sps coral. If that turns out to be the case then might as well buy the regular xr30 and get your UV from the supplemental t5.
