    CO2 at Night

    Dear friends,

    I made a CO2 setup today . And i wana know how do I keep CO2 at night . I cannot turn it off coz I use yeast and sugar mix so once they mixed together they start producing CO2.

    Also plants dont use CO2 at night. So what can I do to save my fish ??

    Every morning only mix up enough sugar/vinegar so that it's over before the lights go out...

    Most DIY solutions are quick dosing since they lack any regulation, the only way to really get slow sustained CO2 is to capture/pressurize it and then regulate how fast it is allowed to escape with a regulator...
