Product Information

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.

Product Handy Hints
JBL Proflora m601 CO2 Set Extension options: 1. Night switch-off with JBL PROFLORA Magnetic Valve (MC108). 2. PROFLORA Special Connection Piece vario (MC109). 2. Automatic pH control unit (see pH controllers) Maintenance: The CO2-vario Diffusion System is made from grey-coloured makrolon, preventing virtually any algae settling in the bubble channel. Cleaning can be carried out when required using clean tap water. The device can be dismantled into its individual components by simply pulling the sections apart vertically. After cleaning, the sections can be simply put back together again. The catch on each module part should be correctly positioned to create a continuous channel for the bubbles. Changing bottles: When the bottle pressure begins to drop below 30 bar, the bottle should be disconnected and refilled or changed for a full bottle. The pressure in the bottle is not an indication of the amount of CO2 contained in the bottle. This can only be ascertained by weighing. The pressure indicated only begins to fall when the bottle is practically empty. Procedure: Close the bottle valve and wait until both pressure gauges indicate 0. Close the dosage valve on the pressure reducer. Unscrew the pressure reducer from the bottle and connect to a full bottle. Carefully open the bottle valve and re-set the number of bubbles required using the dosage valve on the pressure reducer.
