After one year, I have been relatively happy with 3 Hydra 26HDs over a Reefer 450. That said, I wish they were controllable through my Apex, as Radions or most Kessils are.
And, you may find that you want to add T5s eventually, for increased overall intensity, improved spectral coverage, and decreased shadowing. I did, and my corals support that decision.
