Especially for tropical fish and invertebrate species, the right temperature in the aquarium is important so that the aquarium animals feel comfortable. A reliable heater that fits the tank is therefore an important technical component. Dennerle focuses on special heaters for nano aquaristics and offers various nano heaters for mini aquariums. The Nano ThermoCompact, for example, impresses with its short and compact design and is visually discreet in a small aquarium, depending on the size of the aquarium. In addition, the heaters from Dennerle are adjustable and suitable for both freshwater and marine water.
