Description
Nano aquariums have increased in popularity over recent years, but the requirement to add CO2 to promote vigorous plant growth still remains because No CO2 = No Photosynthesis = Dead Plants. Because these aquariums are small, it is often the case that they're not provided with a stand or cupboard, and therefore large/bulky CO2 equipment is difficult to conceal which makes a normal CO2 system unsuitable. Our Nano CO2 System overcomes this problem by using the smallest, but highest quality equipment available, and includes everything needed to create a highly effective CO2 system for your aquarium.
The regulator features adjustable output pressure, which is a rare feature for equipment of this size. It also features a high precision needle valve which can produce accurate dosing control as low as 1 bubble every 10 seconds, which can cater for aquariums as small as 20L. To keep the size to a minimum the regulator is designed to attach directly to small CO2 cartridges, which even for a 100L aquarium will last for up to 3 months, making it a very convenient and cost-effective solution. The regulator also features an integrated 12v DC solenoid valve (mains transformer included) to enable the CO2 be controlled and only dose at specified times, i.e. while the aquarium lights are on. The 12v DC solenoid provides safe, low temperature, and guaranteed no noise operation.
The diffuser is a top of the range 'atomizer' diffuser, which produces a haze of incredibly small bubbles of CO2, providing the very highest levels of diffusion. This ensures very little CO2 is wasted and saves money in the long term.
A nano-sized drop checker is also included to ensure you find the correct CO2 dosing for your specific aquarium needs.
Our Nano CO2 System also comes with all other equipment, including bubble counter, 3m Polyurethane tubing, suction clips, and a support stand for the CO2 cartridge / regulator. In this case, small really is beautiful.

3rd Aug 2026This is a great system for my 40L tank and I'm already seeing much healthier growth from my plants and it's been running reliably since day one. Highly recommended for anyone with a small planted tank.
