Economical and direct
This practical CO2 direct diffuser saves a diffuser in the aquarium, a bubble counter and a check valve. It even saves 20 % CO2 thanks to its ingenious functioning. All that is needed is an external filter with a suitable hose connection.
Easy to install
In order to ensure that the CO2 gas passes as far along the inside of the hose as possible, the direct diffuser needs to be integrated into the hose as close as possible to the external filter. A vertical mounting position will ensure the best readability of the bubble counter.
