The Hozelock Ecocel is a versatile above-ground pond filter that combines mechanical and biological filtration to help maintain clear, clean, and healthy pond water. Ideal for use in a wide variety of pond setups, it can be installed above ground, partially buried, or even discreetly hidden at the top of a waterfall.
- Dual-Stage Filtration for Crystal-Clear Results: Combines mechanical filtration to capture solid waste and biological filtration to break down harmful toxins—supporting long-term water clarity and fish health.
- Flexible Installation Options: The Ecocel can be placed on solid ground, buried into the landscape, or integrated into waterfall features, giving you the freedom to design your pond setup with ease.
- Supports a Balanced Pond Ecosystem: Ideal for wildlife and fish ponds, this filter improves water quality by safely removing debris, fish waste, and dissolved pollutants using a natural filtration process.
- Viewing Hatch for Easy Monitoring: A built-in viewing window allows you to check internal operation and assess whether maintenance or cleaning is needed—making upkeep simple and stress-free.
How the Ecocel Pond Filter Works:
- Water Inlet with Spray Head:
Pond water enters the filter through a spray head, which helps distribute the flow evenly across the filter media for efficient cleaning. - Mechanical Foam Filtration:
The water first passes over a coarse foam sheet that captures larger debris, followed by a finer second foam layer that removes smaller solid particles and suspended waste. - Biological Filtration with Bio Media:
After solids are removed, the water flows through a plastic bio-media chamber. This area provides a large surface area for beneficial bacteria to grow, which naturally breaks down harmful ammonia and nitrites from fish waste and organic matter. - Clean Water Outlet:
The now-filtered water travels upward through the outlet tube and returns to your pond, cleaner, clearer, and healthier. - Scalable Bio Media Capacity:
The amount of bio-media inside the Ecocel increases in line with pond and filter size, allowing it to effectively support larger fish populations and heavier biological loads.


The Hozelock Cyprio Ecocel is a high-performance, pump-fed external pond filter that helps maintain clear and healthy garden ponds by removing solid waste and converting harmful substances into safe compounds. When used alongside a suitable pond pump and UVC unit, the Ecocel delivers enhanced water clarity, reducing algae and supporting the wellbeing of pond life.
- Efficient Solid Waste Removal: The Ecocel effectively captures physical debris, such as leaves and uneaten food, helping to reduce sludge build-up and maintain clean water.
- Converts Fish Waste Into Harmless Compounds: Inside the filter, beneficial bacteria on the bio-media break down dissolved organic waste and harmful chemicals like ammonia and nitrites—improving overall water quality and promoting a healthier environment for fish and plants.
- Ideal for Use Above Ground or Partially Buried: Designed for flexible installation, Ecocel can be placed beside your pond, partially buried into the landscape, or discreetly positioned at the top of a waterfall for a natural look.
- Weatherproof for Outdoor Use: Built with durable, weather-resistant materials, the Ecocel is made to withstand outdoor conditions all year round—but it must not be submerged in water or placed in areas prone to waterlogging.
- Compatible with UVC Clarifiers: For best results, team the Ecocel with a Hozelock Vorton UVC unit to tackle green water algae. Together, they offer a powerful filtration system that keeps pond water clear and sparkling.
Installation Guidance – Important Notice
- This filter is NOT submersible and must always be installed above water level.
- Place the unit on firm, level ground in a safe area where it won’t fall into the pond or become flooded.
- The weatherproof design makes it suitable for year-round outdoor use, provided it is installed correctly.
