Thanks Ray!
I would like to simulate the solar/lunar cycle also...I guess I can do that with cheap timers and cheap blue LEDs too. That would save a ton of money compared to an expensive fixture/controller. I don't think the fish care much about fading light at the beginning and end of the day.
Where did you get your horticultural T5 fixtures?
I still need to shovel out my 100' driveway...ugh.
