Nano CO2 Set — 45g Disposable System

This nano CO2 set provides a complete and immediately usable pressurised CO2 solution for very small planted aquariums and desktop aquascapes. The 45g disposable CO2 cartridge slots directly into the mini regulator, which features a precision needle valve for bubble-rate adjustment. The included 1-metre length of CO2-resistant tubing connects to the compact nano ceramic diffuser for placement inside the aquarium. The entire system is designed to be compact and lightweight, making it easy to position beside or beneath a small tank. The 45g cartridge typically provides 3–6 weeks of CO2 injection in a 20–40 litre tank. Replacement cartridges are widely available, making ongoing use straightforward.
