    This review is about the power: 50 W

    In general, I am satisfied, as this particular thermostat keeps the temperature of my tropical aquarium warm, steadily at 25-26 degrees Celsius. My little fish (Betta) and its tankmates (Amano shrimp and Zebra snails) are very happy. However, I would like to point out that in order for the aquarium to have this temperature, I had to set the thermostat to 30-31 degrees Celsius. At first, I was afraid I was doing something wrong and for weeks I constantly monitored the two thermometers I have in the aquarium. When I was sure that the temperature had stabilized, I relaxed and now everything is fine. Additionally, I will say something very important! With every water change I make in my aquarium, the Eheim thermostat restores the overall temperature almost immediately, even though the fresh water I add is relatively cold.

    This review is about the power: 50 W

    The Eheim Jager 50W thermostat proved to be an excellent choice for my aquarium (about 50 liters). The build quality is evident from the very first moment – sturdy glass body, reliable and safe operation. The German reliability of Eheim is clearly visible in every detail.
