View Full Version : Dusk/Dawn Effect

07/20/2010, 11:16 AM
I'm looking to get a nice dusk dawn effect on my 70 gallon cube. I have 8 T5's and one 250 watt metal halide. I would like it to be three stages: actinics, 14-20k look, then 10-14k look and reverse back.

What bulbs should I use to achieve this with high PAR as I will be keeping SPS?

All advice is appreciated so thank you everyone!
