Re: [APD] O2 and CO2 In Solution

True that the O2 is not being produced in the dark, but the daytime saturation level should keep the nighttime level high enough for fish and plants until morning and beyond. In fact, I think you are more likely to find poor O2 levels in tanks without added CO2 than in tanks with.
Basically, using CO2 (whether on a controller, timer or run 24-7) shouldn't present any O2 problems.

Read the speaker list, then download the registration form, and get set to join the fun at what promises to be the year's biggest tropical fish convention. http://northeastcouncil.org/html/ And while you're there, attend the AGA's annual meeting Friday afternoon (2-4pm). This year's speaker is Claus Christensen, Tropica's Managing Director.

Surely only whilst a light is on?

At night, the CO2 is still getting generated and the O2 is not.
