The JBL M601 CO2 Set provides aquatic plants with the vital nutrient, CO2, easily and conveniently creating the ideal conditions for a luxuriant underwater garden.

At the same time, by regulating the supply of CO2 the pH level can be adjusted to around 7, the range best suited to the majority of fish and plants. So you can be confident that your aquarium is perfectly balanced. Depending on the carbonate hardness, a pH value between 6.8 and 7.4 is recommended.

The simple to use precision pressure regulator has a pre-set operating pressure, so that exact dosages are simply to do. The CO2 is diffused around the aquarium evenly via the Vario Diffuser included, and it can be adapted to fit any size aquarium with an extension set (not included).

The gas bottle containing 500g of CO2 should last a long time, without the need to install a new canister.

A CO2 Permanent Test is included, which remains in the tank to give a constant value of the CO2 in your tank.

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. They absorb this through their leaves.

Easy to install:
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).

The storage cylinder is TÜV tested and is equipped with an overpressure relief. Thanks to the check valve no water can enter the cylinder. The enclosed stand prevents the cylinder from falling over. 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. A 500 g cylinder which is not switched off by a solenoid valve during the night lasts with its default adjustment for about 4 months.
