JBL Protemp III, b20

Sometimes plants like it warm. Substrate or under-gravel heating simulates natural, thermal water currents; this dynamic promotes plant growth and root formation. It also acts as a biological filter and prevents putrid gas formation. The JBL PROTEMP b10-b60 III series offers the right set for aquariums of every size and is easy to install:

Easy to install - lay out the heating cable in loops on the aquarium floor and fix in place with the suction cups supplied. The silicone-coated heating cable and an energy-saving, electronic transformer with 12 V safety extra-low voltage guarantee safety and energy efficiency.

Note: PROTEMP b10-b60 III is the successor to PROTEMP b10-b60 II.
