Computer-controlled underfloor heating for freshwater aquariums. In combination with a heating rod, the sera underfloor heating creates a temperature gradient (1 - 2 °C difference between substrate and water temperature) that promotes water movement in the substrate. This transports nutrients to the plant roots, prevents the formation of dead zones, and utilizes the substrate as an additional filter. The result is stable water values and lush plant growth. The control computer allows for precise adjustment of the desired temperature, while a temperature probe measures the actual temperature. Particularly safe due to low voltage technology.

The set includes:

• 6 m heating cable (plus 2.2 m supply line)
• Control computer with temperature probe
• 10 suction holders for easy installation on the aquarium bottom
• Transformer (24 V).
