The SUNSUN HW-704A external filter is designed for efficient water circulation and filtration in larger aquariums. Thanks to its compact dimensions, it can be easily placed under the aquarium or next to it, and the vibration-damping design helps reduce noise during normal operation.
The model uses a 4-stage filtration system that combines mechanical and biological filtration. The package includes filter sponges, filter floss, ceramic rings, and bio balls; the filter baskets also allow you to customize the media to the specific needs of your aquarium.
Convenient operation is ensured by a prefilter to capture larger debris, a built-in manual pump for quick priming before start-up, and a multifunction valve with a quick connector that allows the hoses to be disconnected without needing to drain them. Also practical are the 360° swivel hose connectors for easier installation even in tight spaces.
