Aquarium CO2 Regulator for Nano and Small Planted Tanks, Dual-Stage Control in a Compact Setup

Give a nano or small planted aquarium a space-conscious pressurized CO2 setup using this compact, all-in-one dual-stage regulator. It fits limited cabinet space and supports standard refillable CO2 cylinders, paintball cylinders, and UNS disposable cartridges, so you can choose the cylinder format that suits your tank and routine.

The compact format brings pressurized CO2 functionality to aquarium stands where a larger regulator setup may take up too much room.

Key Features

• The dual-stage design adds a fail-safe stage that prevents end-of-tank dump, supporting more stable CO2 levels as the cylinder runs low.
• Compatibility across disposable cartridges, paintball cylinders, and standard refillable cylinders gives aquascapers flexibility when choosing a CO2 supply.
• A pre-installed CGA-320 adapter and included paintball adapter make the regulator ready for multiple supported cylinder formats without searching for those adapters separately.
• The included bubble counter provides a practical way to observe CO2 flow as part of a planted-aquarium setup.
• Compatibility with CO2-proof tubing, aquarium diffusers, inline diffusers, and bubble counters makes it easier to fit the regulator into different supported CO2 arrangements.
