Proper Photoperiod

2287 Views 4 Replies 5 Participants Last post by  guerdonian
It seems that many people have multiple photoperiods throughout the day consisting of lights on for a couple of hours, and then off, then finishing with a large photoperiod of four to six hours if not longer. What is the proper photoperiod and what is the purpose of these "on-off" times (algae, photosynthesis, etc)?

the on off times are just to simulate the natural cycle of daylight...sunlight outside isnt just instant light...then instant dark at a certain time

it gradually cycles up and cycles down...so unless 1) they use LED lights (expensive) or 2) have a dimmable ballast (also expensive)...timing bursts are the next best thing

personally...I dont care...so my fish get instant light every morning (they visibly panic) and instant darkness at night (they visibly panic)
