sera soil heating set - computer-controlled floor heating for freshwater aquariums, 1 piece (1 pack)

Computerised floor heating for freshwater aquariums - in combination with a heating rod, the sera floor heater ensures water movement in the soil thanks to a temperature gradient (1 - 2 °C difference between soil and water temperature). As a result, nutrients are transported to the plant roots, prevents the formation of digestion zones and the substrate is used as an additional filter. Stable water values and magnificent plant growth are the result. The control computer allows exact setting of the desired temperature, a temperature probe measures the actual temperature. Particularly safe thanks to low voltage technology. The set consists of: 6 m heating cable (plus 2.2 m supply line), control computer with temperature probe, 10 suction holders for easy installation on the aquarium floor, transformer (24 V)
