JBL Undergravel Heating. Finally - Warm Feet Again!

Aquarium plants grow much better if a heating cable has been laid in the aquarium bottom. This undergravel heating cable doesn’t aim to heat the aquarium water, but to generate warm water around the cable, which then flows upwards through the substrate, leaving colder water to flow between the cables. This creates a current in the substrate to optimally flush the plant roots with nutrients. The result is a visibly better plant growth!

The JBL undergravel heating cables for aquariums were unfortunately not available in two sizes for some time. The JBL development department has managed to come up with an improved technical solution to ensure that only the heat conducting part of the cable really gives off heat to the aquarium bottom and the incoming part of the cable (PTC thermistor) remains cold and does not consume any energy.

The two new versions of the undergravel heating cables are available under the names JBL PROTEMP b40 II and JBL PROTEMP b60 II .
