JBL Proflora Direct 16/22 (Inline Diffuser)
High performance direct diffuser for CO₂
- For an economical and direct plant fertilization with CO₂.
- Will be directly integrated into the hose, coming from the external filter.
- With integrated bubble counter for a precise dosage.
- The check valve prevents water backflow into the CO₂ system.
- 20 % CO₂ saving due to an especially effective diaphragm for the CO₂ diffusion, made of macromolecular PE material.
- This practical CO2 direct diffuser saves a diffuser in the aquarium, a bubble counter as well as a check valve and due to its 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.
FAQ :What working pressure does the ProFlora direct need?
We recommend a working pressure of 1.0 – 1.5 bar.Can the inline diffuser be used in a bio-CO2 system?
We wouldn’t recommend installing the JBL ProFlora Direct in a bio-CO2 system. The working pressure is not big enough to achieve an even addition of the CO2. Moreover, there is a danger that the pressure will not be able to escape through the integrated check valve, and this can lead to damage in the reaction vessel, if it isn’t able to withstand the pressure.I can hear the ProFlora direct whistling / chirping
In this CO2 diffuser the CO2 gets pressed through a fine diaphragm. Depending on the counter-pressure, this sometimes causes a slight chirping sound. If the sound intensifies during operation this indicates a soiling of the diaphragm or change in the operating pressure. Please clean the diaphragm and reduce the operating pressure, if required.Why does my ProFlora direct need more bubbles per minute than my old CO2 diffuser?
The size of the bubbles is essential to providing compatibility. That’s why you cannot compare the number of bubbles in the ProFlora direct with the old method of determining the bubbles (e.g. with the ProFlora Count (safe) or other bubble counters). Depending on the method used, the bubble size can differ by up to 300 %. That’s why it’s important to use the same bubble counter when comparing both systems in order to determine the conversion factor “bubble number in the old bubble counter” to “bubble number in the ProFlora direct”. Since there is no standard CO2 bubble size, it is otherwise difficult to determine the true conversion rate.Why does the membrane need to be soaked in water for 24 hours?
To receive a consistent bubble pattern with fine micro bubbles, the modern ceramic PE hybrid membranes need to be soaked in water before being put into operation. If this is not done, large bubbles will occur.Why does the CO2 Direct create large bubbles?
In order to enable the modern ceramic PE hybrid membrane to build consistent micro bubbles and to ensure an effective
CO2 spread in the water, it needs to be soaked in water for approx. 24 hours before being put into operation. Do not, therefore, switch on the CO2 supply after installation until the period of time mentioned has passed. Alternatively you can put the membrane into a bowl of water. Without this soaking the pores will not have enough water and will let large bubbles pass with an uneven distribution.The bubble counter doesn’t fill with water. What can I do?
If there is no water in the bubble counter after the installation, just wait a few hours before switching on the CO2 supply. The water jet of the filter will then cause water to enter it. Alternatively while installing it, you can fill the chambers of the bubble counter with water.The check valve doesn’t seem to let CO2 pass through it. What can I do?
Please wait until sufficient pressure has built up in the CO2 hose. Alternatively you can sharply increase the CO2 supply for a short time.
