Bought to heat a 200 liter aquarium. Judging by the reviews - the heater should be more than enough. Also, the advantage of Aquael heaters is the ability to set the temperature, as well as to find out the current temperature in the aquarium. In general, I have a part of the "equipment" in the aquariums of this particular company and have never had any complaints (external filters are generally handsome). As a result - let's see how the next heater will manifest itself. If suddenly something - I will change the review later, while everything is fine :)
