I have a tek light luminaire with 4 54watt t5's (216watts Yay!!). This will go on top of a 64 us gallon planted tank. I can turn two sets on independently of each other. How do you recommend i time the lights to come on. I was thinking a total 8 hours lighting time. With all 4 t5 's on 5 hours as a midday burst. How does that sound?
