Dual-stage regulators
Pro-SE or Pro-Elite?
Both are dual-stage, so the pressure does not surge when the cylinder runs low, the fault single-stage regulators are known for. The difference is how much pressure they give you, and how steadily they hold it.

- Best for
- Several aquariums off one cylinder, manifolds, and the steadiest bubble count.

Le vert intense de la Monte Carlo contraste à merveille avec les Manten Stone et apporte beaucoup de fraîcheur au paysage. 🌱
Les engrais ADA apportent juste ce qu’il faut à ce bac, et la photosynthèse de la Monte Carlo est tout simplement magnifique à observer. Ces petites bulles d’oxygène qui se forment sur les plantes agissent comme note de musique 🤩
Ce que j’aime particulièrement avec cet Iwagumi, c’est de le voir évoluer avec le temps, prendre progressivement vie et révéler peu à peu tout le potentiel du hardscape.
Et vous, vous aimez découvrir les coulisses et le setup d’un aquarium, ou vous préférez simplement admirer le rendu final ? 💚🌱

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 ? 💚🌱

Nano high-tech planted tanks demand extra care. Here’s what actually matters for a successful setup:
*The Non-Negotiables:*
Stable CO2— @co2art regulator + timer. No swings.
Strong filtration — Hang-on filter, oversized for the tank.
Quality ferts — @masterline.ro all-in-one, dosed daily.
Proper light — @arowanaspectro Full-spectrum RGB, 8hrs max.
Plant mass — Start heavy. Plants outcompete algae.
Weekly maintenance — 50% water change + trim. Non-negotiable.
Rich substrate — Aquasoil base for roots + nutrients.
Beneficial bacteria — @microbelift Special Blend to kickstart cycle.
Clean-up crew — Shrimps + ramshorn snails do the work.
Soft water — @arkaaquatics RO + @greenwateraquascapes GH-Enhancer for stability.
Most important rule: Never overcrowd with livestock. Low bioload = stable tank.
That’s my secret to keeping nano tanks in perfect shape.
Hope this helps. Happy aquascaping, everyone 🌿

Product description
The new generation of our highest-rated dual-stage regulator, designed for aquarium safety and fine precision. Built for aquariums from 5 to 5,000 litres.
The dual-stage construction keeps the output pressure steady as the pressure in the cylinder drops, and prevents an end-of-cylinder dump whatever size of CO2 cylinder you use. The fully customised solenoid block carries an integrated medical-grade needle valve and a bubble counter.
Features
- Safe 12 V DC integrated solenoid valve
- Power adapter with universal voltage, 100–240 V
- Adjustable working pressure up to 5 bar
- Stainless-steel dual gauges: cylinder contents and working pressure
- High-precision integrated needle valve
- Bubble counter with a built-in check valve
- Extendable manifold block
- Compatible with any size of CO2 cylinder, thanks to the two-stage construction
- Thread to the UK, European, Japanese and Taiwanese standard (BS341 / DIN477 / W21.8x14) or CGA320
More than one aquarium?
Add as many outlets as you like with the manifold block: one block per extra aquarium or diffuser, fitted or removed at any time.
The product manual and the installation video are in our help centre.
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
