Recommended photoperiod for LEDs?

[advanwoerden]

Hello all,

I have a DIY LED system with 12 cool white and 24 royal blue Cree XPE's, 12 LED's per MeanWell driver. Thanks to Buck0land who tested my par, and determined that the majority of the rockwork is around 150-450 par, with most around 350. I currently have the whites and blues on separate timers, with 6 hours for white and 10 for blue. I also have 3 blue XPEs for moonlights for the remaining 14 hours. Any suggestions as to how I should tweak the timing, if at all?

Separately, anyone know of any good references for coral preferences based on par and not just "low, medium, or high"?

Thanks!

Anyone have any thoughts on the photoperiod? Any suggestions or comments would be greatly appreciated!

My setup is similar to yours.

2PM - 12AM - XP-E Royal Blues (~800mA)
4PM - 10PM - XP-G Neutral Whites (~800mA)
24 Hours - (3) 350mA Royal Blues for moonlights

PAR-wise, I've had a friend test - 600ish by water surface, 300-500s midlevel and around 200s on the sand. No optics, but I'm running around 72 diodes within a 36x24 area.

Thanks Widdy! A few questions for you:

-What's your ratio of blue to white, and why did you use neutral vs. cool white?
-How big is your tank?
-How long have you been running that schedule, and how do you find it?
