CO2 Diffuser P-Series (inner reactor)

CO₂ (carbon dioxide) dissolves in the water. You can easily observe this phenomenon when you watch a CO₂ bubble on its way to the water surface: it shrinks.

In order to maximize the contact of the gas with the water and to guarantee a high dissolution, the AQUA-NOA CO2 diffusors of the P series atomize the gas into minute bubbles. Many of them don't even reach the water surface since the CO₂ has dissolved entirely in the water on their way up. A diffusor is a highly efficient method of getting as much CO₂ into the water as possible and to provide the aquarium plants with the vital carbon they so urgently require.

All AQUA-NOA internal CO₂ reactors / AQUA-NOA CO₂ diffusors of the P series are equipped with:

• a very finely pored ceramic membrane
• a 4/6 mm CO₂ hose connection with a union nut
• suction cups for mounting on the aquarium glass

Optionally, the types PS/PM 2 and PS/PM 3 are available with:

• a bubble counter for easy visual control of the amount of CO₂ that is injected
• a check valve that protects the solenoid valve and/or the pressure reducer from water

The combination of these additional functions in one device saves you several lengths of hose that would not only be unsightly but might increase the risk of leakages.
There is only one direct CO₂-tight or silicone hose connection from the solenoid valve or the CO₂ pressure reducer to the CO₂ diffusor.

The connection of the AQUA-NOA CO₂ diffusors of the P series is secured with a union nut. Use standard 4/6 mm CO₂ hose that is usually part of any CO₂ set available in trade.

Please note: The AQUA-NOA CO₂ diffusors of the P series (internal CO₂ reactors) can be used with CO₂ injection systems using one-way or refillable cylinders of all brands, but not with yeast-based CO₂ fertilization.
