Description
The Evolution Aqua Tempest Filter is a high-efficiency pond polishing filter designed to deliver exceptional water clarity in koi ponds and advanced filtration systems. Acting as a final-stage filter, the Tempest is engineered to remove fine particles that pass through primary and secondary filtration, resulting in visibly cleaner and clearer water.
Developed by Evolution Aqua in the UK, the Tempest Filter is ideal for koi keepers who demand polished, crystal-clear water conditions. It is commonly used as part of a multi-stage filtration setup alongside Nexus or other biological systems.
Why use the Tempest Filter
Even well-filtered pond water can still contain fine suspended particles that reduce clarity and impact the visual quality of your pond. The Tempest Filter is designed specifically to address this final stage of water polishing.
Key benefits include:
- Removes fine suspended solids for polished water clarity
- Improves overall visual quality of the pond
- Works as a final-stage filtration unit
- Low maintenance operation
- Enhances performance of existing filtration systems
How it works
Water is passed through a high-performance media chamber designed to trap fine particulate matter. Unlike primary filters, the Tempest focuses on “polishing” the water rather than removing heavy waste loads.
This makes it an ideal finishing filter in koi pond systems where biological and mechanical filtration is already in place.
Ideal application
The Tempest Filter is best suited for advanced koi pond systems where water clarity is a priority. It is commonly installed after biological filtration units to refine water quality to a professional standard.
It integrates easily into Evolution Aqua setups and is often paired with Nexus systems or similar filtration equipment.
