Product information

Clean and healthy water
Plant and food remains and metabolic substances lead to a deterioration of the quality of the water in the aquarium. Good water quality is necessary for healthy fish and plants. This can be achieved with aquarium filters. The filters suck in the aquarium water and remove the pollution and waste materials from the water. Filters also offer an ideal habitat for bacteria which decompose harmful substances.

Increase of oxygen content
The diffuser draws air into the outlet water and thus increases the oxygen content without dispelling too much CO2 out of the aquarium water.

Easy to install
Fit diffuser onto the water outlet of the internal filter. The set also fits all 12/16 mm hose connectors. The air supply is adjustable.

Optimal safety
The diffuser is equipped with a check valve.

Technical Data

How can I remove the hose from the device?

At first the air hoses and special CO2 hoses can easily be pushed on the connection piece. The hoses harden more and more as the months go on and can only be removed from the connection piece using great force. If you pull the hose hard it will only strain the connection, which could, in the worst case, even break off. Instead cut the hoses you want to remove laterally at the ends and carefully remove them. For this it’s always advisable to install hoses with some reserve in its hose length.
