GLA Nano CO2 system $65
This is a Greenleafaquarium (GLA) nano all in one CO2 system. It is a proprietary system and as far as I know you have to get replacement cartridges from them. Comes with 1 full cartridge, everything you need to get started. I used it on a 20g and the tank lasted about a month, maybe a little longer.
The Atomic Nano V1 CO2 Kit includes:
Atomic V1 CO2 regulator with super precise needle valve and speed-fit tubing connection for ease of installation. Features fixed working pressure, designed specifically for use with Atomic CO2 diffusers.
74 gram disposable CO2 cartridge / cylinder.
Heavy duty, CNC alloy cylinder stand with integrated O-ring and scratch + slip protective base.
5 feet of CO2 resistant, pressure rated tubing
