The Ultum Nature Systems CO2 Mini Regulator fits perfectly on these CO2 Cartridges for an ultra space-saving look! Regulator models dating prior to 2020 are not compatible with this replacement cartridge.

This 90-gram replacement CO2 Cartridge Bottle makes implementing CO2 injection in a planted aquarium tank simple and fast. Pre-filled, each CO2 cartridge bottle will last anywhere from 2-3 months based on a 5-gallon aquarium tank depending on usage. This CO2 Replacement Cartridge Bottle is recommended to be used on planted aquarium tanks up to 20 gallons in size. For larger aquarium tanks, pressurized CO2 systems using a paintball cylinder or regular CO2 cylinder system kit is recommended. CO2 refills are quick and easy. One can simply twist off, swap it out, reconnect a new cartridge to ensure your planted aquarium tank will have a new and consistent supply of CO2. This is the perfect planted aquarium CO2 option for those looking for a small form factor and simple yet reliable CO2 injection system.

CO2 Cartridge Bottle Base Stand
This CO2 Cartridge Bottle Stand ensures that the CO2 Cartridge stays in an upright position.

This CO2 Cartridge Bottle Stand will prevent unnecessary gas build up and potential danger to the user and aquarium inhabitants.

Why CO2 injection is important in a planted tank: 3 main factors contribute to the optimal growth of aquatic plants. These factors include nutrients, light and carbon dioxide (CO2). If any of these are unbalanced, the results are algae growth or the withering of plants. The introduction of CO2 in a planted aquarium allows plants to thrive and grow more efficiently, while also giving them the ability to outcompete algae for nutrients. 

No matter what type of planted aquarium setup you have, we recommend CO2 injection for better aquarium plant growth.
