Product information

Nutrition for aquarium plants
Plants provide the aquarium with vital oxygen for the aquarium dwellers, prevent algae growth, remove pollutants, provide hiding places and reduce pathogens.
The JBL plant fertiliser systems supply the plants with the main nutrient CO2 through the water. This way the plants can absorb all the required nutrients they need over the leaves.
Easy to install
The system comes completely ready for connection. Screw the pressure reducer onto the CO2 storage cartridge. Connect the pressure reducer with the hose to the diffuser in the aquarium. The CO2 enters the aquarium and is dissolved in the water by the diffuser. The CO2 supply can be interrupted at night by adding a solenoid valve (not included).
Safe
The storage cartridge is PI approved. Thanks to the check valve no water can enter the cartridge. The enclosed stand prevents the cartridge from falling over. The capacity of a CO2 system depends on various factors. Here the carbonate hardness, the quantity and species of the plants and the strength of the water surface movement are decisive. A 95 g cartridge which is not switched off by a solenoid valve during the night lasts with its default adjustment for about 4 months.

FAQ
How can I dispose of my disposable CO2 cylinder?

You can dispose of the empty cylinder as household waste or by taking it to scrap-metal recycling. It is important that the cylinder is completely empty.

Is there anything I need to know when dealing with CO2 pressurised gas cylinders?

You must observe two points:

1) Cylinder: Reusable cylinders are TÜV tested and this is stamped on the cylinder. This test must be renewed every 10 years, with the bottom of the cylinder and the valve sealing and threaded joint being tested.

2) The carbon dioxide:
Depending on its concentration, carbon dioxide is harmful in the air. From: http://www-organik.chemie.uni-wuerzburg.de/misc/betr_ein/uw-g15.html : The respiratory rate and pulse rate increase at a carbon dioxide concentration of 3-5%. Other symptoms are headaches, discomfort and ringing in the ears. Carbon dioxide concentrations of 8-10% and more cause these symptoms to become more pronounced. This may lead to cramps, fainting, apnoea and death from suffocation.

One 500 g cylinder contains 500 g CO₂. This is equal to 11.36 mol (chemical substance amount unit). One mol of a gaseous substance has a volume of 22.414 l under normal conditions (273.15 K, 101325 Pa), so that 500 g of CO₂ result in a volume of 254.7 l. CO₂ is heavier than air, so that it collects on the ground. This corresponds to a CO₂ height level in the range of 12.735 mm = 1.27 cm for a room of 20 m². If it is mixed completely with the air in a room of 20 m² and a height of 2.5 m (corresponds to 50,000 l), this corresponds to a maximum gas concentration of 0.5 volume %, which is well below the dangerous level.

After installing the JBL ProFlora compressed gas system, no CO₂ enters the reactor. However, the cylinder pressure and working pressure displayed are in the proper range.

Please check whether the check valve (JBL SafeStop) is installed properly. It should be installed as the last element before the reactor and with the tip of the arrow pointing to the reactor (JBL Taifun).

Where did my algae come from?

Algae problems in an aquarium can never be traced to just one factor or general condition, and instead, are always the result of a combination of different factors, which include light, fertilization, water changes – specifically, how often and how much – feeding, fish population and, of course, the specific water parameters.

According to analyses that were performed over a course of a number of years, red algae, at least the common brush algae and beard algae, occur in descending order at the following parameters:

1) too little carbon dioxide (in relationship to 100 % of the measured tank); the pH level should be in the slightly acetic range, depending on the carbonate hardness, in every case.
2) elevated phosphate levels (over 90 %); phosphate limitation by means of JBL PhosEx ultra is often helpful here.
3) too little and too irregular fertilization (there should always be traces of iron at least).
4) insufficient water changes; a weekly water change of over 30 % is recommended for algae problems.
5) not enough fast-growing plants.

What’s the best way to deal with brush and beard algae?

1. Increase the volume of water changed each week to about 30-50%.

2. Fertilise regularly after the water change, e.g. with JBL Ferropol.

3. If necessary add a daily dose of Ferropol 24.

4. If algae promoting nutrients (especially phosphate) are present in higher quantities, use JBL PhosEx ultra to keep them under control.

5. Most important is carbon dioxide. Beard and brush algae are always a sign that there is too little carbon dioxide in the water. If a CO2 system is in use, increase its dosage. Alternatively consider installing a CO2 system like JBL ProFlora u401 or m601.

6. Put in fast growing stem plants as nutrient competitors.

7. If there is strong current, reduce it slightly.
