JBL bottom heater ProTemp b40 III is a modern substrate heater for planted freshwater aquariums of approx. 90-300 L capacity
. Aquatic plants grow better in the wild when they have access to seeping nutrition sources. The plants absorb their food from these sources. The gently warming undergravel heating causes the warm water to rise and the cold water, full of dissolved nutrients and minerals, sinks to the bottom. This creates a thermal water flow, which washes the minerals and trace elements directly to the roots.
When beginning to set up the aquarium, position the heating cable of the JBL ProTemp b40 III in even-sized loops (in the area where plants are to be planted) on the cleaned bottom pane. Using the slotted suction cups enclosed, fasten the heating cable. Bring the cold leads of the cable out of the aquarium and connect them to the power supply. The black markings on the cable clearly distinguish the cold lead from the heating cable.
The heating cable is silicone-covered and works with an energy-saving power supply with 24 V safety voltage for hazard-free use. The the power supply unit needs to be mounted in a well-ventilated, splash-proof place. The undergravel heating results in a slight warming of the substrate, but definitely needs to be supplemented with a heater thermostat or a thermofilter for warm water fish.
