JBL - ProTemp S 300 - Aquarium Heater - 300w

Aquarium heater
The fish adapt to the outside temperature. The vital functions of cold-blooded animals drop with the temperature. It is therefore very important to have the right temperature in the aquarium to ensure that the fish feed without problems and to guarantee a perfect functioning of the metabolism. The temperature at which fish feel good varies according to their origins.

Easy setup
Insert the heater into the supplied protective basket, select the temperature on the adjustment wheel and submerge the heater in the aquarium at least to the minimum water level line. Fix it with the suction cups. As soon as the heater is connected to the mains, the indicator lamp lights up. The heater can also be installed horizontally, e.g. ex. in turtle tanks.

Optimal heat transfer
JBL's secure adjustable heater provides optimal temperature transfer within the range of 20-34°C. The adjustment wheel ensures an adjustment precision of +/- 0.5°C. The maximum temperature that can be reached will depend on the volume of water and the temperature difference with the surrounding space.

Safe adjustable heating
The protective grid in which it is inserted prevents fish from getting burned. The heater is waterproof, submersible up to 100 cm and its 2 mm safety glass ensures it is very solid. When the water level drops or the heater is removed from the water, the safety thermostat cuts off the power supply to protect against overheating. The heater is TÜV approved (German inspection).
