Question New tank, reduce photoperiod or led intensity?

Hey everyone,

I recently started a high-tech, co2 injected 20G long. I'm running a co2 atomizer (soon to be a reactor since I'm not loving this sprite look), Fluval 3.0 LED's and dosing Thrive x3 a week. It's not super heavily planted until I can get get some additional plants and growth.

My question is, should I run the Fluval LED lights at full intensity over a shorter period (let's say 4-5 hours) and increase the photo period over time or alternatively run the lights at about 50% intensity over a longer 10-12 hour period and increase the LED intensity over time? Right now I'm running the latter.

Your thoughts and advice would be appreciated.

*Picture below is with the LEDs at 100% intensity.

I would say 100% intensity for shorter duration. If it were me I would start at 6 hrs, but some of the other folks might have more experience dialing in the photoperiod than myself.
