Dupla Thermic Set 240, 40 Watt
Art.-Nr.: 80681 Description: Ground convection heater for activating roots in aquariums up to 240 liters. The Dupla Thermic Set warms the substrate material alone. The resulting temperature difference causes oxygen-rich water to circulate into the lower substrate layers and nutrients to circulate into the upper layers. For aquarium heating an additional regulated heater is necessary. Supplied with safety isolating transformer. Manual: Thermik Set
