Pro-SE Series Complete Aquarium CO2 System with InLine Diffuser

Dual-stage regulator and the accessories that go with it, for an aquarium with an external canister filter. Everything you need to start injecting CO2 through the filter is in the box, except the CO2 cylinder.

The dual-stage construction keeps the output pressure steady as the pressure in the cylinder drops and prevents an end-of-cylinder dump, so your livestock stays safe and the CO2 level constant.

What is in the kit

• PRO-SE Series dual-stage CO2 regulator with an integrated solenoid
• Aluminium bubble counter
• Inline CO2 diffuser
• CO2 drop checker set
• CO2-resistant tubing

The regulator comes with a W21.8×14 (BS341 / DIN477)

For an aquarium without an external filter there is the same kit with the in-tank Flux_ diffuser.
