The JBL ProTemp b III series consists of heating cables wich are buried in the aquarium soil and cares for a thermal flow through the substrate. This thermal flow creates areas of water circulation within the soil, like they are also found at the natural plant habitat. The build-up of anoxic areas within the soil is prevented which means that putrefaction and formation of toxic hydrogen sulphide is stopped. At the same time the water circulation takes nutrients to the roots facilitating plant growth.


Installation of substrate heating

The JBL ProTemp b comes in different wattages. Please note, however, that they are not suited for heating the entire aquarium. Therefore, the ProTemp b III does not need temperature regulation. The heating cable is made from resilient silicone and connects with the inverter power-supply via two normal cables. The new bigger diameter of the cables enables a safe operating voltage of 24 V.

You shouldn't use fine sand with the ProTemp b III since it prevents the water circulation.
