Good to know

Running CO2 safely

Start slow and watch your fish.

  1. 01

    Use a timer

    Turn CO2 on before the lights and off before they go out.

  2. 02

    Increase gradually

    Raise the bubble rate slowly over several days.

  3. 03

    Watch for gasping

    Fish at the surface means too much CO2. Turn it down.

Common questions

Before you choose.

Do I need CO2 for a planted tank?

No. Many plants grow well without it. CO2 is for faster growth, carpets and strong red plants.

Is CO2 safe for fish?

Yes, at the right level. Increase slowly and turn it down if fish gasp at the surface.

Should CO2 run at night?

No. Plants only use it while the lights are on, so run it on a timer.
