Well I always heard to have a night/lights-out for planted tanks, but of course that was for rooted plants in soil tanks. I get that a plant is alive and performing it's functions even in the dark, so I believed (and shared) the advise to have a dark time. If this supposition is not correct, what is the scientific evidence? Is down time just about the water CO2 level? And fish comfort?
What then is the ideal photo period for a rooted-plant NPT with fish inhabitants? Keeping in mind algae and any other important factors.
:confused:

I have heard of lots of different time frames also. I have been doing a 14 hr period with an afternoon break of 2-3 hrs for a while and they seems to help keep the BBA at bay. (unless I forget to do the lights out afternoon.) Thank you everyone. I want to give the plants what they need.:thumbsup:
