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 ? 💚🌱

This growth of the plants is really amazingly beautiful I had an aquarium before it without a great CO2 system from CO2 type and there it did not work as it should but since I have this CO2 system, my plants grow wonderfully. Thank you to @co2art

@divertigo42petit retour après 4 jours de l'installation du kit CO2 art. enfin une diffusion parfaite du CO2. il faut savoir que le CO2 est votre allié contre la lutte de la prolifération d'algues car il se joue dans les bacs une compétition acharnée entre les plantes et les algues. alors...petit retour après 4 jours de l'installation du kit CO2 art. enfin une diffusion parfaite du CO2. il faut savoir que le CO2 est votre allié contre la lutte de la prolifération d'algues car il se joue dans les bacs une compétition acharnée entre les plantes et les algues. alors CO2 ou pas CO2 pour moi le choix est fait depuis longtemps c'est CO2 mais avec un kit performant.#aqurium #aquariophiliefrancais #antialgues #kitco2aquarium

Premium CO2-resistant polyurethane tubing for planted aquariums, 4/6 mm, rated for high pressure. Made for our CO2 accessories and complete kits.
This tubing is different from most on the market in what it is made of: the wrong material turns brittle and leaks gas, this one lasts indefinitely. It fits every CO2 glass diffuser in our shop.
Colours and lengths
- Clear, black, silver, transparent blue and transparent green
- 3 metres or 6 metres
Tip: to fit the tubing onto CO2 glassware, dip the end in boiling water for two seconds and push it onto the glass.
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
If you are not satisfied with the quality of a product within 30 days of purchase, we send a full refund or a replacement at no charge. Mechanical defects found during the first year are repaired, with any parts needed, at no cost to you. The guarantee
