Please refer to the actual product. Then, we'd like to remind you: Water spontaneously evaporates in the air, so it's necessary to regularly check the water level line and add new water. The optimal water level is about 5 - 8 centimeters away from the top of the fish tank. It needs to be at a relatively high-water level to operate properly. - Regularly check if the water pump is working properly. (Occasional noises when the filter is operating are normal.) If the water pump stops working, there may be debris stuck inside. Try disassembling and cleaning it. If it still doesn't work properly, please contact our after - sales service. When raising tropical fish, regularly check the water temperature and maintain it within the suitable range for the fish (22 - 30 degrees Celsius). The common white spot disease is often caused by large fluctuations in water temperature. - Change the water once a week, replacing about one - third of the water each time. Add nitrifying bacteria again each time you change the water. Filter Plate Replacement: The filter plate, filter cotton, and filter media need to be replaced regularly to maintain an adequate number of nitrifying bacteria in the water. Add nitrifying bacteria again each time you make a replacement. This product is of the XP series, XP - 06, and is suitable for fish tanks with a length of less than 35 cm and a height of about 15 - 21 cm. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0876FQVYG | | Batteries Included | No | | Best Sellers Rank | #2,342 in Pet Supplies ( See Top 100 in Pet Supplies ) #86 in Aquarium Accessories | | Color | white | | Customer Reviews | 4.1 4.1 out of 5 stars (59) | | Date First Available | 25 July 2019 | | Item Weight | 230 g | | Product Dimensions | 8 x 8 x 17 cm; 230 g | | Quantity | 1 | | Size | 1 Count (Pack of 1) | | Voltage | 240 Volts | | Wattage | 3.5 watts | | batteries required | No | ## Images ![Aquarium Hang On Filter Water Oxygen Circulation Pump Fish Tank Waterfall Water External Filtration - 3.5W - Image 1](https://m.media-amazon.com/images/I/71v7kO7ELeL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by H***H on 20 October 2024* Does the job ### ⭐⭐⭐⭐ How to get it working *by F***X on 31 March 2021* The product instruction is in Chinese.
