CO2ONE Complete CO2 system (in-tank)
Carbon Dioxide (CO2) fertilization is, by far, the most important investment you can make for your planted aquarium. CO2 starvation, inevitable in almost every planted aquarium, results in slow, spindly growth and endless battles with nuisance algae. Some of the most spectacular species will simply die off slowly, melt away, and rot. Increasing the supply of CO2 unleashes the full potential of your aquatic plants and the effects are virtually instant - like turning a knob.
Some benefits include:
Growth rates five to 10 times faster
Sturdier, more robust structures
Lusher foliage
Brighter, more vibrant colors
Rapid production of oxygen (pearling)
Dramatically reduced algae and improved water quality
Delicate, picky species are easy to grow with CO2
Despite its obvious advantages, many aquarists opt out because CO2 injection is often complex, impractical, and expensive. Our CO2ONE system is a new approach entirely that makes CO2 injection accessible to even a beginner.
A complete system that sets up in minutes, CO2ONE works with easy-to-find SodaStream canisters that are practical, inexpensive, and super convenient. A 410g SodaStream canister lasts 6-10 weeks for a typical 30-gallon aquarium. It also works with Paintball canisters and standard CGA320 CO2 cylinders.
Watch your aquarium plants explode with dense luxurious growth and brilliant colors. There is literally nothing else you can do that will make as much of a difference!
This kit comes with an in-tank diffuser and is compatible with any aquarium (up to 100 gallons) with any type of filter. If you have a very large aquarium with an external canister filter, consider our in-line system.
Compatible with traditional rimmed and rimless aquarium tanks
Diffuser Options:
"NANO" diffuser for tanks up to 30 gallons
"Bazooka" diffuser for larger aquariums.
