A JUWEL aquarium can be operated extremely cost-efficiently. It is important to remember that the electricity consumption depends on various factors, such as the size of the aquarium, the power of the pump, the lighting and the water temperature.
To measure the electricity consumption of a typical JUWEL aquarium, we took into account 8 hours of lighting per day, an ambient temperature of 22°C and a water temperature of 24°C, as well as three summer months without heating.
Based on an electricity price of 40 cents per kilowatt hour, the average electricity consumption of a JUWEL aquarium is about 29 cents per day. The precise electricity costs will depend on the model of the aquarium, as shown in the table below:

We guarantee all of our products for 2 years from the date of purchase. Filter sponges and fluorescent tubes as well as all components that are subject to normal wear, e.g. the impeller of the pump, are excluded from the guarantee. Any guarantee claim must be substantiated with a valid proof of purchase.
No. Our aquariums are produced using robot-supported processes. This includes the automated application of silicone to the bottom pane. The bulge is merely a point where the applied silicone seams overlap, which is necessary for production. This does not affect the leak-tightness of your aquarium. You can use the aquarium without any reservations.
Thanks to specially developed float glass, JUWEL aquariums can bear a multiple of their filled weight. Please make sure, however, to observe your base cabinet’s load capacity. For details about the maximum load capacity, please see the technical data provided on our website.
