Water level: Water evaporates naturally in the air, so it is necessary to check the water level regularly and add new water. The best water level is about 5-8 cm away from the top of the fish tank, and the high water level can work normally!\r\n 2. Aquarium Filter pump inspection: Regularly check whether the pump is working normally (occasionally when the filter is working, it is normal work). If the pump does not work, there may be debris stuck inside. Disassemble it and try to clean it, if it cannot resume normal work , Please contact our after-sales.\r\n 3. Change the water and wash: Change the water once a week, and change about one-third of the water each time; each change needs to re-add nitrifying bacteria.\r\n 4. Replacement of the filter plate: The filter plate, filter cotton and filter material need to be replaced regularly to maintain sufficient nitrifying bacteria in the water, and nitrifying bacteria need to be re-added for each replacement.\r\n 5. Filter plate replacement cycle: The replacement cycle is about 1-2 months. The filter plate is replaced according to the water quality of the filter pump.\r\n 6. Filter material: You can choose our filter plate to replace (13.5*5.2cm), or you can buy some large filter cotton from other suppliers, and then cut out the same size and fill it into the aquarium filter. It can also be filled with others filter materials such as activated carbon and bio ball filter media and bio balls ceramic rings set.
