Product description

The highest-quality CO2 system on the aquarium market: our best-rated dual-stage regulator, the Pro-Elite Series V2, with the latest inline diffuser and the accessories that go with it — for an aquarium with an external canister filter.

For peace of mind, this regulator gives the best pressure stability and an unbeatable 10-year warranty. With the extendable manifold blocks you can add outlets and run several diffusers from one regulator.

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-Elite Series V2 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 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 without an external filter there is the same kit with the in-tank Flux_ 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. Delivery is fully tracked with FedEx: 1–2 business days in Europe, 3–5 worldwide. Customs or import duties outside the EU are charged on arrival. Shipping policy · Returns
