The classic Oase Biotec 5.1 returns as the highly upgraded Oase BioSmart 18000 Pond Filter. Designed as the ideal entry-level flow-through filter, this system effectively removes pond debris and breaks down toxic chemicals, keeping your aquatic ecosystem thriving. Its clever internal design supports a high flow-through rate (up to 5,500 lph) while maximising oxygen enrichment. For the ultimate clear-water setup, the BioSmart 18000 pairs seamlessly with Oase Vitronic or Bitron C Ultraviolet Clarifiers (UVCs).
Advanced Filtration & Monitoring with the BioSmart
- Specialised Filter Foams: Featuring a targeted combination of blue, red, and green foams, the filter provides a massive surface area. This area ensures optimal biological development, enabling beneficial bacteria to efficiently break down harmful ammonia and nitrites.
- At-a-Glance Diagnostics: Taking the guesswork out of pond care, a built-in pollutant level indicator lets you know exactly when maintenance is required, while the integrated thermometer helps you track water temperatures during seasonal shifts.
Effortless Placement & Maintenance
- Hassle-Free Cleaning: Routine maintenance is incredibly convenient. Simply pump the easy-cleaning handles to compress the sponges, then pull the integrated slide valve on the sludge drain to flush the waste away, all without getting your hands dirty.
- Landscape Friendly: Because the unit can be buried up to one-third of its height, it is much easier to conceal this flow-through filter behind garden foliage or rockwork.

Is this filter compatible with all pond pumps, or are there specific pump requirements?
As long as the pump you select accepts 25, 32 or 38mm flexible hose and is less than the maximum flow rate of 5500 lph then it would be compatible.
