Un immense merci à eux pour leur confiance. Je suis très fier de faire partie de la famille des COArt Artists ! 💚
Ça faisait un moment que je n’avais pas réalisé d’iwagumi… Du coup, j’hésite : partir sur un iwagumi pur et traditionnel ou tenter une version revisitée ? 🤭
J’ai déjà quelques Manten Stone à la maison qui iraient parfaitement dans ce bac, pour les connaisseurs. 🤩
Et vous, vous partiriez sur quelle option ? 💚🌱

Our latest inline CO2 diffuser. It sits in the outlet hose of an external filter, so there is less equipment in the aquarium and a cleaner look — without giving your plants any less CO2.
Features
- Replaceable ceramic membrane
- Two sizes: 12/16 mm and 16/22 mm hose
- Durable, crack-resistant metal body
- Nano CO2 mist membrane
Good to know
This diffuser needs a working pressure of at least 30 psi (about 2 bar). Use CO2-rated tubing only, never silicone: the tubing must be acid-resistant and rated for high working pressure.
Fill the bubble counter with water only — bubble counter fluids and oils contaminate the diffuser.
How a CO2 diffuser works
A diffuser makes the CO2 entering the aquarium easier for plants to take up and wastes less of it. As the gas passes through the porous membrane it breaks into streams of tiny bubbles; with their larger surface area they dissolve readily into the water and raise the CO2 saturation of the aquarium.
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
Warranty and lifetime support
The Advance Professional and Professional dual-stage regulators carry a warranty of up to 10 years; every other CO2Art product carries the standard 2-year manufacturer's warranty. All customers receive lifetime free online technical support. Warranty terms
Satisfaction guarantee
