Running Lights?

[Jgomez324]

How long should I run my lights. 4 ATI bulbs. SPs tank.

I'd say 8 hrs on daylights and 10hrs on the dusk, dawn lights

 

[ironworker]

how big is your tank.

I would agree. 2 bulbs on for 10 hours and all 4 bulbs on for 8 hours. I have a gap of one hour on each end of the day for half of my lights to be off.
