  • Sets a new standard for efficiency and performance in the industry.

How the Filtration System Works

Mechanical Filtration

Foam filter stages capture solid debris, reducing waste build-up.

Biological Filtration

Filter media encourage beneficial bacteria that help break down waste.

Performance Characteristics

When correctly installed, the system delivers high flow at low head heights, with reduced output as pumping height increases. Performance varies with sunlight and installation conditions.

Flow Rate by Pumping Height

Height Flow (Direct Solar) Flow (Battery Backup)
0 m Up to 1800 LPH Up to 1400 LPH
0.5 m Approx. 1500 LPH Approx. 1100 LPH
1.0 m Approx. 1300 LPH Approx. 900 LPH
1.5 m Approx. 1000 LPH Approx. 350 LPH
2.0 m Approx. 700 LPH 0 LPH
Max height 3.5 m 2.0 m

Performance figures are indicative and based on controlled testing. Results vary with sunlight, season, and installation.

How the Solar Pond Filter System Works

Solar Energy Collection

The solar panel converts sunlight into DC electricity to power the pump and filtration system during suitable daylight conditions.

  • Uses solar energy only
  • No mains electricity required
  • Best performance in direct sunlight
  • Zero ongoing running costs

Power Distribution

Electricity generated by the panel is supplied directly to the pump, with energy managed automatically depending on light conditions.

  • Solar-first operation
  • Automatic power management
  • Performance varies with sunlight
  • No manual control required

Mechanical Filtration

Water passes through foam filters that capture leaves, debris, and suspended particles before returning to the pond.

  • Removes visible debris
  • Helps maintain water clarity
  • Protects pump from blockages
  • Easy-to-clean filter media

Biological Filtration

Filter media provide surface area for beneficial bacteria, supporting natural breakdown of waste compounds.

  • Encourages beneficial bacteria
  • Supports pond ecosystem balance
  • Helps manage fish waste
  • Natural filtration process

Water Circulation

Continuous water movement helps distribute oxygen and reduces stagnant areas within the pond.

  • Improves water circulation
  • Supports oxygen exchange
  • Reduces stagnant zones
  • Promotes healthier pond conditions

Optional Battery Backup

When fitted, the battery stores excess energy generated during sunny periods and can supply power during reduced sunlight.

  • Stores energy from daylight
  • Supports extended operation
  • Performance depends on charge level
  • Weather-dependent behaviour

Seasonal Performance

Solar pond filter performance varies naturally throughout the year due to changes in daylight and sun angle.

  • Strongest performance in spring and summer
  • Reduced output during autumn and winter
  • Shorter run times in low-light months
  • Seasonal adjustment improves results

Automatic Operation

The system operates automatically, switching between available solar input and stored battery energy where applicable.

  • No manual switching required
  • Designed for outdoor use
  • Solar-first energy usage
  • Battery used when available
