JBL Proflora Direct 16/22mm

This diffuser replaces the bubble counter and non-return valve in the aquarium. Thanks to its thoughtful function, it even saves 20% CO2. All that is required is an external filter with a suitable hose connection.

Easy to install
In order for the CO2 gas to flow as far as possible along the inside of the hose, a straight diffuser must be integrated into the hose as close as possible to the external filter. The vertical mounting position provides better readability of the bubble counter.
