AllPondSolutions Aquarium Hang on Filter 5W UV - black

The AllPondSolutions 500L/H Aquarium Hang-on + Filters are suitable for fresh or saltwater aquarium fish tanks up to 115 litres capacity. The built-in UV steriliser fights against algae growth and promotes the cleanest and clearest water for your aquarium plants and livestock. Filter Operation: The internal pump draws water from your fish tank in through the intake tube then exposes it to a UV light bulb for sterilisation. The water continues to flow through multiple stages of filtration and through the waterfall-effect outlet back into the tank.
