how long do you guys run your lights for?
I run for like 12-14 hours and was wondering if this was too much
12 to 14 hours is not too much in my opinion. As long as you don't get any algae blooms you should be fine. I always try to think about what our critter's natural environment is like and go from there. You figure the sun comes up anywhere from 6am to 7am and doesn't set until 8 to 9pm, which is anywhere from 14 to 15 hours. So if you're doing actinics for an hour first, then 12 hours of full light, and an hour of actinic at the end that should be fine.
