【Important Note】After receiving the product, must remove the shock-proof sponge inside the product before using it. (For detailed steps, please refer to the third product picture in the product page.) 【Warm Prompt】Since this product contains a small motor to drive the water circulation, there will be a loud motor idling sound when running without water; but once submerged in the water, the sound will disappear. In addition, in order to ensure the best performance of the machine, we have checked all the machines (in water) before shipment, so after receiving the machine, it may be wet inside, please do not worry, it is brand new. 【Product Detail】Size: 3.5" L X 3.9" W X 12" H, Cord: 4.6ft., Flow rate: 210 gallon per hour, suitable for 40-80 gallon tanks. Four-in-one: water pump(adjustable) + air pump + filter + clean, can be directly used in the fish tank without other connection requirements. 【Warm Tips】In order to maintain the best cleaning effect, it is recommended to check the machine every 1-2 weeks: open the casing, 1. clean the filter sponge, 2. check whether the bulb works well, 3. check whether water enters the quartz sleeve. Since the bulb generates heat during operation, it may cause slight water into the quartz sleeve after long-term use. If there is a little water into the sleeve(which does not affect the bulb, just drain the water). 【1 Year Warranty】For any questions or problems, please contact the service mailbox on the package, and we will solve and reply in 24 hours.
