Any reason not to use a cycle like 8 on - 8 off? Would it potentially give 50% more growth than the 8 on 16 off cycle I run now?

Anything is worth a try.
I have thought about trying 8 on with maybe 1-2 hours off.

I'm no way scientist, but would bet 1-2 hours will not restart algae grow cycle.
Try a 6:6 schedule so it will align with the 24 hr. schedule that you live on. Lighting cycles for ATS are one area that need a lot more research. Check out this blog for some interesting circadian rhythm information: http://circadiana.blogspot.com/2005/...or-not-to.html.
You can pulse the light on and off over 1000 times a second and photosynthesis keeps up. You need a longer off cycle then the on cycle though as it builds the product quicker then it distributes it. Floyd and I have talked about building a timer for a LED driver to experiment with this. Theres more to it then my little sentence. Its a lot to read. I have it saved on my laptop somewhere. Floyd my have the articles on his machine, I dont use my laptop since I work at home now. If Floyd cannot find them I will dig them up.

Today I just started a 4 on, 6 off, 4 on, 10 off cycle for a total of 8 on hours. Will see what results this brings.
Kerry: Correct me if I am wrong but I highly doubt that respiration occurs between the flashes when using
PWM.
WannaRace: Based on absulutely no scintific evidence, it seems like you ought to keep the length of each cycle consistent so that the circadian rythm of the algae can be more easily entrained. Wouldn't it be strange if the sun rose 2 hours early every other day?
Indeed.
Basing off SM's data from chaeto. 4 on 4 off 4 on 12 off would work better?
I'm trying to ease the burning on the screen without reducing intensity of LEDs.
