How long does everybody keep their co2 going for?

[Markahsf]

I'm trying to figure out what's best for me but I would like to know what everyone else does. My photoperiod is anywhere from 6-7 hours a day.

What's your photoperiod and how long do you keep your co2 running during that period?

Thanks.

My photoperiod is 8 hrs and I start the co2 one hour before lights on and eend 1 hour before lights off. (So 8 hrs co2 ,just one hour earlier.)

you can get a cheap timer to get your lighting schedule set consistently. I usually start my co2 an hour before lights on, and 45min. before lights off on my 36g. My flora is near a window that gets a little light in the morning, so my co2 for that comes on 1.5 hours before lights on, and turns off 45 min. before lights off.

10 hour photo period and 8 hour co2. I turn on the co2 at the same time I turn on the lights. I turn off the co2 whenever the sun goes down.

I start an hour before the lights turn on and turn off an hour before the lights turn off

Co2 24/7, photoperiod 8 hrs

[Steve001]

Tank naturally lighted. Photo period varies with the seasons, but isn't less than 8 because I use some supplemental lighting.

Co2 runs 24/7

mine runs from 6am to 8pm

Mine runs for 10 hours on a 125G tank.

9 hrs lights.. 10 hrs co2. I kick the co2 on two hours b4 lights turn on and it shuts off a hour b4 they turn off.

This way when lights go on co2 is already well distributed around the tank. Works quite well

Photoperiod is 7hrs. Run co2 2hrs before lights on and off 1hr before lights off. I have lots of surface agitation so it takes a bit longer for me to get good co2.
