Very high-quality design: anodised aluminium, precisely CNC-milled in titanium colour, low-noise solenoid valve. Reliable sealing washer instead of O-ring The system comes completely ready for connection. Screw the pressure reducer onto the CO2 storage cylinder. Connect the pressure reducer with the hose to the diffuser in the aquarium. CO2 thus enters the aquarium and is dissolved in the water with the help of the diffuser. The CO2 supply can be interrupted at night by an interposed solenoid valve (not included). I have just spent 1000s on a new tank and all the hardware and part of this kit was the JBL PROFLORA m502: The sets of the "BASIC" range contain all components to visibly promote the growth of aquarium plants by adding CO2. You have the choice between a set without a CO2 supply cylinder (VARIO system), if a cylinder is already available, with a disposable CO2 storage cylinder (U system) or a refillable CO2 storage cylinder (M system).

It sounds like a good idea to be fair, the automatic control of CO2... after just 24 hours of trying to get this 502 working, haha, Connect sensors (pH sensor not included), set desired values in menu, connect with solenoid valve (not included)Professional plant care with night switch-off: precise dosing by means of pressure reducer, even release, effective distribution due to extendable diffuser, best monitoring with bubble counter, CO2/pH test, residual pressure display on pressure gauge The CO2 and planting equipment range can be split into the following categories; aquarium probes, aquarium plant fertiliser, aquarium planting substrate, aquascaping, CO2 and iron test kits, CO2 and planting equipment pipework & fittings, CO2 bottles, CO2 pressure gauges, co2 sets, CO2 solenoid valves, diffusers, planting accessories. Aquarium probes, also known as aquarium electrodes, monitor the presence of CO2 within your aquarium water. Aquarium plant fertiliser is just like regular fertiliser however it is designed not to mix with the water, which can create a murky tank. Aquarium planting substrate is similar to soil for regular plants but formulated for aquatic use. Aquascaping includes all the tools needed to perform many modern aquascaping techniques. CO2 and iron test kits are simple chemical tests to determine the presence of CO2 or iron within your water. CO2 and planting equipment pipework & fittings has everything you need to set up your CO2 hardware and connect it with your tank. CO2 bottles are simply storage canisters of CO2. CO2 pressure gauges monitor and regulate the pressure within the CO2 bottles. CO2 sets contain all the hardware needed to add CO2 to your aquarium. CO2 solenoid valves are timed valves used to help you stop or start adding CO2 to your system. Diffusers spread CO2 throughout your aquarium to ensure they reach all of your plants. Finally planting accessories is made up of various tools and spare parts useful to aquatic gardeners. What should I look for?

Please note: When fertilising with so-called liquid carbon, fertiliser monitoring with JBL PRO AQUATEST CO2 Direct is not possible because these fertilisers do not con-tain CO2 but other carbon compounds. Procedure: The pressure reducer fits disposable CO2 cylinders (U system) and refillable cylinders (M system). By unscrewing the knurled nut (W21.8x1/14) with an Allen key, the pressure reducer fits the M10x1 thread of the disposable cylinders The number of drops multiplied by 2 gives the carbon dioxide content in mg/l. Example: 10 drops of reagent 2 = 20 mg/l CO2. The system comes completely ready for connection. Screw the pressure reducer onto the CO2 storage cylinder. 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.When using disposable cylinders, the adjustment knob for the working pressure is also the valve for opening your CO2 cylinder. When using refillable cylinders, you have an additional cylinder valve, open this first. The cylinder pressure now shows you a pressure of approx. 60 bar. This means that the cylinder is sufficiently filled and you can continue with the next steps. The system comes completely ready for connection. Screw the pressure reducer onto the CO2 storage cylinder. 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). Live plants provide the aquarium with vital oxygen for the aquarium dwellers, prevent algae growth, remove pollutants, provide hiding places and reduce pathogens. The ProFlora range of JBL plant fertiliser systems supply the plants with the main nutrient CO2 through the water. They absorb this through their leaves. The perfect addition to creating a beautifully scaped live planted aquarium.

the remaining bottle pressure as well as the adjusted working pressure. 3. JBL pressure reducer for 2 aquariums Since other acids in the water impair the measurement, a blank value must also be determined. To do this, take a water sample of 100 ml and aerate it for 15 min using a JBL ProSilent air pump with an air stone. Then determine the blank value according to the instructions given above. These systems are easy to install and ready for connection. Simply screw the pressure reducer onto the CO2 storage cylinder. 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. elevated phosphate levels (over 90 %); phosphate limitation by means of JBL PhosEx ultra is often helpful here.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. They absorb this through their leaves. Professional water care with night switch-off: precise dosing thanks to pressure reducer, even release, effective distribution due to extendable diffuser, best control due to bubble counter, CO2/pH test, residual pressure display on pressure gauge Why test? Carbon dioxide (CO2) is the most important plant nutrient. The consump-tion of CO2 differs from aquarium to aquarium and depends, amongst other things, on the following factors: number and demands of plants, carbonate hardness, water movement and light. Fertilisation with CO2 is usually done with a CO2 fertiliser system. In the aquarium water, a CO2 content between 15 and 30 mg / l is recommended. This range is safe for fish and at the same time ensures luxuriant plant growth. 20–25 mg/l CO2 has proven to be ideal. In special aquariums with a large number of plants, higher values of up to 35 mg/l may be required. CO2 sets are the perfect accessory for planted aquariums to help achieve and maintain strong, healthy and attractive aquatic plant life. They can regulate the amount of CO2 that is given and many kits allow you to adjust the range to suit your fish and plants.

Plants provide the aquarium with vital oxygen for your aquarium inhabitants, prevent algae growth, remove pollutants, provide hiding places and reduce pathogens. The JBL plant fertiliser system supplies the plants with the main nutrient CO2 through the water. The plants absorb this through their leaves.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 system supplies the plants with the main nutrient CO2 through the water. They absorb this through their leaves. Now turn the adjustment knob for the working pressure, the large screw knob between the two pressure gauges, and observe the right-hand pressure gauge for the working pressure. The green range up to 1.2 bar is marked. Open it so far that the desired working pressure is reached. The adjustment of the screw allows the opening up to approx. 1.2 bar. 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. Plants boost the aquarium with vital oxygen for the aquarium dwellers, prevent algae growth and remove pollutants. CO2 systems supply the plants with the main nutrient CO2, through the water. This helps improve the water quality, boost the health of both fish and plants, and also keep algae and related compounds at bay.
