JBL PROTEMP b20

• A floor heating system ensures a nearly natural thermal circulation of the soil substrate and thus promotes the transport of nutrients to the plant roots.
• Easy installation: lay the heating cable in loops on the bottom glass of the aquarium, secure it with the suction cups.
• The rising heated water is followed by an influx of colder water, thus ensuring water circulation in the soil. The soil also transforms into a natural filter for the aquarium.
• Large cross-section of the heating cable for higher output, 24 V safety voltage against hazards, and a high-quality power supply unit. Spring clamps allow for tool-free assembly.
• Contents: aquarium floor heater, power transformer, heating cable with hot/cold conductors, fixing suction cups.

Water circulation
In nature, aquatic plants grow best when they have nutrient-rich runoff sources. The plants feed on these. Due to the slight warming of the soil, water rises, and cold water, full of dissolved nutrients and minerals, descends, creating a thermal flow that brings food directly to the roots.

Simple installation
Lay the heating cable in regular loops (in the area where plants are to be planted) on the cleaned bottom glass. Secure the heating cable using the provided slotted suction cups. Take the 2 cold conductors out of the aquarium and connect them to the power supply unit. The separation into cold and hot conductors is clearly visible by the black lines on the cable.

Safe use
For safe use in the aquarium, the heating cable is silicone-coated and operates with a low-voltage 24 V power supply unit. Install this unit in a well-ventilated and splash-proof location. The floor heating ensures a slight warming of the soil substrate but must be supplemented by an immersion heater (JBL ProTemp s) for tropical fish.
Power supply units heat up during operation, which is normal and purely technical.

Tip
Those who do not wish to use suction cups to fix the heating cable can permanently secure it with small drops of silicone and then remove the suction cups.
