PRODUCT DETAILS

Crystal Clear Pond Water — Without the Guesswork

Green, murky pond water is one of the most common frustrations for pond owners. The Gravity Feed Pond Bio Filter with built-in 36W UV Light tackles the problem at its source — eliminating harmful fish waste, algae-causing sunlight penetration, and bad bacteria, while cultivating the good microorganisms your pond ecosystem needs to thrive.

Suitable for ponds up to 18,000 litres (at low fish stock levels). Complete with all filter media included — just connect and run.

How It Works

Water enters the filter box and passes through the 36W UV steriliser, which neutralises algae spores and harmful bacteria. It then flows through two chambers of coarse foam blocks and plastic bio-balls, which trap solid waste and provide a growing surface for beneficial microorganisms. Clean water exits via the outlet back into your pond.

Why Choose This Filter?

  • 🟢 All-in-one solution — mechanical, biological, and UV filtration in a single unit
  • 🟢 Complete kit — all filter media included, nothing extra to buy
  • 🟢 Gravity-fed design — no pressure pump required for the filter itself
  • 🟢 Easy maintenance — hand-clean the mechanical foam when needed
  • 🟢 Bio-balls included — maximise surface area for beneficial bacteria growth

💡 Best results tip: Pair with a WH4000 or WH3000 pond pump for optimal flow through the filter. Undersizing your pump is the most common cause of poor filter performance.

Whether you're keeping koi, goldfish, or a planted wildlife pond, this combo gives your water the biological balance it needs to stay clear and healthy year-round.
