Any changes on co2?

Sooo going to be filling up my co2 tank next week. Debating, should I let my co2 run 24/7? At a decreased rate? (my tank has good surface agitation)

Or get another solonoid and kick it on and off?

Waste of CO2 if you run all night. No one likes filling up their tank...

The problem is that the answer depends on how much light you are using. If you have really high light, and have to use a high concentration of CO2 in the water, you should shut the CO2 off at night, because the plants will stop using CO2 at night, letting the concentration increase a bit, and that can harm the fish. But, with lower light levels, where not as high a concentration of CO2 is needed, the rise in concentration at night will not be enough to harm the fish, so shutting off the CO2 isn't essential. I think a pH controller can protect the fish even with high light concentrations of CO2, but I'm not sure of this.
