Product description

Our most popular dual-stage regulator and the accessories that go with it, for an aquarium without an external filter. Everything you need to start injecting CO2 is in the box.

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
  • In-tank Bazooka Flux_ CO2 diffuser
  • CO2 drop checker set
  • CO2-resistant tubing
  • SS-Series stainless-steel U-bend with four suction cups

The regulator comes with a CGA320 thread for North America or W21.8x14 (BS341 / DIN477) for Europe and the rest of the world — you choose it on this page. Not sure which? Our guide to cylinder connections in the help centre explains the two.

For an aquarium with an external filter there is the same kit with an inline diffuser.

Shipping and delivery

Free delivery on orders over €200; otherwise €9.99 in Europe and €14.99 for the rest of the world. Orders placed before 2 PM CET are usually processed the same day — a regulator may need a little longer, because every one is assembled and tested before it ships.
