The JBL ProTemp b series consists of heating cables wich are buried in the aquarium soil. They form 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.

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 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 power-supply transforms the 230 V mains voltage into a safe operating voltage of 12 V.

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

Gesundes Wurzelwachstum

JBL - ProTemp b - 10 watts
JBL - ProTemp b - 10 watts

Preis/Leistung geht in Ordnung. Durch die Wasserzirkulation im Bodengrung gibt es keine Fäulnisherde mehr. Das Wurzelwachstum wird hierdurch emens gesteigert.

Gute Alternative zum Dupla Thermik Set!!

JBL - ProTemp b II - 40 watts

Deutlich kleineres Netzteil, das sich zur Wandmontage (im Schrank) eignet. Heizkabel machen einen guten Eindruck. Die Saugnäpfe haben ein gutes Haltevermögen. (read more)
