The ISTA CO2 External Reactor is an external inline CO₂ reactor designed for planted aquariums using external filters or canister filters. It helps dissolve CO₂ into the water before it returns to the aquarium, keeping the tank cleaner with less visible equipment inside.
This reactor uses a patented impeller design to constantly break down CO₂ bubbles inside the transparent chamber. This increases contact time between CO₂ and water, helping improve CO₂ dissolution and reduce gas loss compared to regular in-tank diffusers.
The ISTA CO2 External Reactor fits 12/16mm hose pipes and 13mm hose type filters. It is easy to clean, simple to maintain, and works without electricity because it uses the water flow from the filter. It is not directly suitable for 17mm hose unless reducers are used on both sides.

FAQ
1. What is ISTA CO2 External Reactor used for?
It is used to dissolve CO₂ efficiently in aquarium water through an external filter or canister filter line.
2. What hose size does it fit?
It fits 12/16mm hose pipes and 13mm hose type filters.
3. Does it need electricity?
No, it works using the water flow from the aquarium filter.
4. Is it suitable for 17mm hose?
No, it is not directly suitable for 17mm hose. You may need reducers on both sides.
5. Why use an external CO₂ reactor?
It keeps CO₂ equipment outside the aquarium and improves CO₂ dissolving through the filter water flow.
