Features 1. You are purchasing a high-quality aquarium with built-in filters and UV sterilizers, suitable for aquariums with a capacity of no more than 160 liters. Adding ultraviolet sterilizers to aquariums can effectively kill suspended algae (green water), microorganisms, bacteria, and parasites, which may cause fish diseases and improve water quality transparency. 2. This series of filters comes in two specifications: a 500 liter/hour water pump with a 5-watt ultraviolet sterilizer, and an 800 liter/hour water pump with a 9-watt ultraviolet sterilizer. Please select the desired model from the drop-down menu above. 3. This built-in filter can also be used in conjunction with the main filtration system, only providing UV sterilizations function. 4. The filter is equipped with foam prefiltering sponge as standard, and a venturi tube can be selected. If necessary, oxygen can be added to the water returning to the aquarium. 5. Both models are equipped with ultraviolet lamp status indicator lights, which can visually confirm the working status of the lamp. Comes with installation brackets and suction cup components to ensure that the filter is firmly attached to the side wall of the aquarium. Important reminder: The replacement quartz lamp cover does not include sealing ring accessories.
