CO2 System – a complete CO2 kit

This kit is intended for aquarium keepers who want to add CO2 to a planted tank without building a homemade yeast setup. Instead of loose yeast mash, the bacteria are held in a gel matrix, which gives a more even CO2 output over time and removes the need to monitor a fermentation batch by eye.

Why it matters

• Gel matrix: the bacteria can reach the nutrient only through the top surface of the gel, so the mash is consumed gradually and the bacteria release a steady amount of CO2.
• Dosing duration: in about 90% of cases the gel and bacteria last roughly 50 days. Lower temperatures can extend dosing to around 60 days, while higher temperatures shorten it.
• Diffuser: the NEO diffuser has an acrylic body and a ceramic sinter, which the manufacturer describes as denser than competing products, to improve CO2 dissolution.
• Refill cycle: after about 10 days the bacteria start to weaken. The liquid is then poured out, the gel is left in the bottle, and a new bacteria sachet is added with fresh water.

What it works with

The kit is designed for the planted freshwater aquarium category, where CO2 is supplied to plants through a diffuser placed in the tank. Dosing duration depends on the temperature of the container, so the setup suits keepers who can keep it at a stable temperature. The package does not specify a maximum tank volume, so check the dosing rate against your own tank before use.
