Product information

Nutrition for aquarium plants
Healthy plants are important for every aquarium. Plants supply the aquarium with vital oxygen for the aquarium dwellers, prevent algae growth and remove pollutants.

Healthy plants = healthy fish
Healthy plants prevent algae growth, supply oxygen, remove pollutants, provide hiding places and reduce pathogens.

For the plants to flourish the following demands need to be met: Light as energy source for the photosynthesis of CO2, nutrients and trace elements as growth promoters.

JBL fertilisers supply the plants with all main nutrients and essential trace elements through the water. This way the plants can absorb all the required nutrients they need over the leaves and roots.
The capacity of a CO2 system depends on various factors. The carbonate hardness, the quantity and species of the plants and the strength of the water surface movement are decisive.

Bluish discolouration despite increased CO2 supply

Owing to a production fault a green colour change may not occur with the batches 1000 and 1001, despite increased CO2 supply.

Should you have one of the above mentioned batches, you can request a new refill set free of charge upon presentation of the sales receipt and a photo of the batch number. Please contact our customer service under: https://www.jbl.de/support/

JBL ProFlora u500: How can I dispose of my disposable CO₂ cylinder?

You can either dispose of it with your general household rubbish or with scrap metal when it is empty. Ensure that the cylinder is completely empty.

Is it bad if water runs into the bubble counter?

If water runs back into the bubble counter, that’s not a problem as long as the water is not drawn towards the night time shut-off from there. The excess water is normally pressed out of the system again during the day.

JBL pH-Control: When the appliance is connected and switched on, there is often a pulse-like formation of enormous bubbles at the CO₂ - air stone, so that the fish become frightened. Afterwards, the desired formation of bubbles is present again. When the electromagnetic valve in the controller is switched off, the pressure in the entire system from the cylinder to the pressure reducer and the tubes and to the electromagnetic valve persists. When the valve is opened, the pressure in the system escapes first and then the system continues to operate as usual.

When the electromagnetic valve in the controller is switched off, the pressure in the entire system from the cylinder to the pressure reducer and the tubes and to the electromagnetic valve persists. When the valve is opened, the pressure in the system escapes first and then the system continues to operate as usual.

You can decrease / prevent this by reducing the operating pressure in your pressure reducer. In our new pressure reducers, this can be done with an Allen wrench under the black cover top.

JBL ProFlora m500, JBL ProFlora m2000, JBL ProFlora u500: Is my system broken if there is a rapid and marked drop in cylinder pressure towards the end of the charge?

The rapid drop in the cylinder pressure shortly before the end of the charge does not constitute grounds for complaint, and instead, is normal and unavoidable from a technical standpoint.

Reason: The cylinder is filled approximately halfway with liquid carbon dioxide. You remove gaseous CO₂ from the cylinder; the corresponding share of the liquid CO₂ passes to the gaseous phase; the pressure remains constant. It isn’t until less CO₂ passes from the liquid phase to the gaseous phase that the cylinder pressure begins to drop.

This means your system is functioning normally.

There’s more to fertilization than you’d think Part 2

Simply put, Liebig’s Law of the Minimum states that the growth of plants is limited by the scarcest resource. Adding a nutrient which already exists in abundance does not influence the growth.
