SUNSUN Aquarium external filter 9W UV HW-703B

The SUNSUN HW-703B is an external aquarium filter with a built-in 9 W UVC clarifier, designed for freshwater and saltwater tanks of up to 600 litres. Its pump delivers up to 1400 l/h and works with a four-stage filtration system that combines mechanical and biological filtration. The UVC lamp helps reduce the growth of algae, bacteria and other microorganisms, supporting clearer water.

The spacious filter basket holds a range of media, and the package includes filter sponges, filter wool, ceramic rings and bio balls. Chemical media such as activated carbon can also be used. The hoses rotate through 360 degrees, and a multifunction valve with quick connectors lets you disconnect the hoses without draining the filter. Baskets with handles make media removal and cleaning quick.

The filter runs fairly quietly, and rubber feet dampen vibration. The ABS and PVC housing carries an IPX4 water-resistance rating, and the maximum lift height is 2 metres.
