Pond filters and their application areas
We provide an overview
Selection of the right filter technology for your pond establishes the foundation for sustainably clear water. Every garden pond imposes individual demands on the filter system or the pond filter. Whether an underwater filter, pressure filter, flow-through filter, or a module filter is used depends on factors, such as pond type, pond volume and fish stock.
This brief overview shows you the four filter categories and briefly explains the main features of each pond filter system.
Underwater filters
Optimally suited for:
- Decorative pools such as galvanised troughs or wine barrels
- Pre-fabricated pools up to 5,000 litres
- Small ponds
- As supplemental filter element with fountain
With the OASE underwater filters you create a beautiful feature even where space is at a minimum. View products
Pressure filters
Optimally suited for:
- Medium-sized ponds up to 30 m3
- Direct infeed of watercourses or fountains
- Architectural pools without visible technology
Pressure filters are suitable for small and medium-sized ponds. If needed the water can be routed to higher positioned watercourses because the pump pressure remains intact through the filter. View products
Flow-through filters
Optimally suited for:
- Larger ponds up to 140 m3
- Ponds with fish stock
- High circulation capacities
Flow-through filters are used for medium-sized to large ponds or koi ponds. They stand above the water surface at the edge of the pond, or above a watercourse, so that the water flows back into the pond under gravity. View products
Module filters
Optimally suited for:
- Large ponds, swim ponds, koi ponds and lakes
Large natural ponds or swim pond with or without koi - these modular systems remain flexible at all times. View products
