The new JBL ProFlora direct is a high performance direct diffuser for CO2. This practical CO2 direct diffuser saves a diffuser in the aquarium, a bubble counter as well as a check valve and due to ist unique functioning it also saves 20% CO2. The only prerequisite is the use of an external filter with a suitable hose connection. The direct diffuser needs to be integrated as close as possible to the external filter to extend the distance of the CO2 inside the hose as much as possible. A vertical mounting position ensures best readability of the bubble counter.
