Howdy! Apologies, I'm a bit confused at the question.
Are you asking how long for a photoperiod?
How high are the lights from the top of the water, additionally, what bulbs do you have in it?

 

[Marthin Muller]

Yes photoperiod in total for all bulbs and /or 2 bulbs
2 bulbs are blue ATI and 5 Bulbs are 3 each of ATI blue and white

Can always just ramp up to 8 hours and see how it goes from there.

Thanks SantaMonica.. currently at 10 hours for 2 blue and the rest for 8

Shoot for 12 total. And, if you get tired of that greenish blue windex look of the Blue plus bulbs, look into a purple plus bulb.
