Plants only absorb CO2 when your lights are on, so there is no point in adding gas at night time. Not only is it wasteful, but carbon dioxide binds to oxygen and you can cause major distress or death in your livestock.

The Colombo CO2 Solenoid should be used with a domestic timer (just like your lights timer) and automates when your CO2 comes on and off. I recommend it comes on 1 hour before your lights come on and turn off 1 hour before they go off (this is optimal). By using this solenoid you will not only save a lot of gas, reduce any risk to your fish/shrimp and save you plenty of money (as you won't need to purchase CO2 bottles as often!).

Hi I understand that this is made in Holland. Can you tell me if it comes fitted with a UK plug or continental plug with an adaptor? Also does it come with instructions some i'm clear how to set it up? Many thanks for your assistence Paul


UK plug and instructions included :)

how long after it switches off will the co2 actually stop .. i seem to have bubbles still after 2 hours ?


Sometimes it takes a while depending on your diffuser and pressure left in the tubing

Hi can this be used with the Fluval CO2 Kit 88g Pressurised kit?


Not sure. Depends if your instructions say a Solenoid can be used with it

Can this be used with the 90g Colombo CO2 regulator?


sadly not
