Aqua Advanced 2 HEAD (supplies 2 tanks) Dual Gauge Aquarium CO2 Regulator + Aus Warranty

Aqua Advanced (with 2 READY HEADS) Dual Gauge CO2 Regulator Features:

Ready to Support 2 Aquariums and Can Be Extended to Support 6 Aquariums

By default, this unit comes with 2 modules installed to provide CO2 to 2 aquariums.
It can support up to 6 aquariums through additional module extensions, which can be purchased separately.

If you have the budget, this is one of the best investments for planted aquariums, as CO2 will significantly improve the growth of aquarium plants, and most hobbyists usually grow their aquarium hobby with more planted tanks.

Dual Gauge & Reliable

Dual gauge shows 2 pressure readings which are Working/Delivery Pressure (shows the reduced, safe pressure of CO2 being pushed into your aquarium's bubble counter and diffuser) and Cylinder Pressure (shows the amount of CO2 left in your tank).

Aquarzon tested this model, and when the CO2 is gradually used up from the tank, the CO2 regulator pressure gradually decreases as well (which avoids the end-of-tank CO2 gas dumping accidents that often affect older, cheap single-stage CO2 regulators, which are lethal to fish and shrimp, as it causes them to suffocate).

2026 New Tech Bubble Counter

The new, modern bubble makes it super easy to install CO2 tube. Just press the top white rubber ring to insert CO2 tube. No need to struggle anymore with traditonal bubble counter that require forcing the airline tube into the hole.
