In the past two weeks I switched over to two Hydra 26's and replaced the t5 fixture that came along with my new setup. So far no troubles with the lights and I run them with the AI controller. Only thing I might've done differently is get the director instead of just the controller, not much more expensive and I'm assuming it would be a little bit easier to work with. But otherwise I'm loving the lights and would recommend them. Too soon to speak of coral color or growth but I have had great results with a different LED fixture recently, LEDs are the way to go, IMO.
