Ecocel

£0.00

The Hozelock Ecocel is a durable above-ground pond filter designed to deliver clear, healthy water through a simple yet effective dual-stage filtration process. By combining mechanical filtration to remove debris and biological filtration to break down fish waste and toxins, Ecocel supports a clean and balanced pond environment all year round.

Key Features & Benefits:

  • Effective Mechanical & Biological Filtration: The Ecocel uses foam filters to trap solid waste and bio-media to encourage the growth of beneficial bacteria, which help break down harmful ammonia and nitrites—keeping your pond clean, clear, and fish-friendly.

  • Ideal for Above-Ground Installation: Designed for easy placement outside your pond, the Ecocel is quick to install, simple to maintain, and perfect for ponds of various sizes.

  • Supports Long-Term Pond Health: This filter promotes a healthy aquatic ecosystem by naturally removing waste, reducing sludge build-up, and improving water clarity over time.

  • Combine with a Vorton UVC for Complete Clarity: For maximum effectiveness, pair the Ecocel with a Hozelock Vorton UVC clarifier. The Vorton eliminates green water algae, while the Ecocel filters out the remaining waste—giving you crystal-clear pond water with minimal maintenance.

Whether you’re maintaining a wildlife pond or a fish pond, the Hozelock Ecocel offers a dependable and low-maintenance filtration solution, ideal for keeping your water feature in top condition.

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:

  1. 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.
  2. 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.
  3. 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.
  4. Clean Water Outlet:
    The now-filtered water travels upward through the outlet tube and returns to your pond, cleaner, clearer, and healthier.
  5. 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.

3921 3923 lifeEcocel

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.
