I sort of ramp up and down my lights, having sunrise, morning, mid day, afternoon and sunset. I run 2, 120W Apollos (not controllable) and 1, 120W (165W) Mars Aqua with blues at 100% and whites about 33%. With these three fixtures I can control the two channels, white and blues. In addition I have 2, 4 foot IceCap LED nightlights (relatively bright), that are part of the cycle. The cycle mimics equator lighting.....a 12 hour light period.
Sunrise (Nightlights) ------------ 1 hr ------- 10AM-11AM
Morning (Blues only) ------------ 3 hr ------- On at 11AM
Mid-day (Blues and Whites) --- 4 hr -------- 2PM - 6PM
Afternoon (Blues) ----------------3 hr -------- Off at 9PM
Sunset (Nightlights) --------------1 hr ------- 9PM-10PM
I will most likely be installing Fathom Hydras when I switch out my current (broken) tank. These lights are fully controllable, with ramping, so I'll be following this thread.
