Q ：How is the filtration effect of this filter? Can it really make the water clear to the bottom in a short time? A ：Yes, our filter uses advanced filtration technology and a multi - stage circulation filtration system to effectively remove impurities and pollutants from the water. According to actual tests, it can significantly improve water quality and make the pond water clear to the bottom within 3 - 7 days. However, the specific effect may vary slightly depending on the initial water quality of the pond, the number of fish and the amount of feeding.

Q ：Is the UV - C sterilization system harmful to fish? A ：The UV - C sterilization system is designed to target harmful microorganisms in the water and will not harm the fish. Our UV - C lamp is designed reasonably, and the light will not directly irradiate the fish. It can effectively protect the health of the fish while sterilizing.

Q ：What are the advantages of wet - dry separation filtration design and how to maintain it? A ：The advantages of wet - dry separation filtration design are that it improves filtration efficiency and facilitates maintenance. It divides the filtration materials into dry and wet areas. The dry - area filtration materials can more effectively adsorb and filter large - particle impurities, while the wet - area mainly focuses on biological filtration and further water purification. In terms of maintenance, you can easily replace the filtration materials in the dry and wet areas separately. The operation is simple and convenient, greatly reducing the difficulty and time cost of maintenance.
