Effective Biological Filtration

Hozelock K3 Biological Filter Media provides a suitable surface for beneficial bacteria to establish and develop within your pond filtration system.

As pond water passes through the filter chamber, established bacteria help convert harmful ammonia into nitrite and subsequently into less harmful nitrate, supporting stable biological filtration.

This makes K3 media a practical choice for pond keepers looking to maintain effective biological filtration and suitable water conditions for koi and other ornamental pond fish.

Moving Bed & Self-Cleaning Design

K3 media features a wheel-shaped structure and slightly positive buoyancy, allowing it to circulate within a suitable moving bed filtration chamber.

Air supplied through an air pump, air stones or diffuser creates movement within the chamber, causing the media to circulate and gently collide.

This continuous movement helps reduce excessive waste accumulation and supports a self-cleaning action, reducing the need for frequent manual cleaning.

Ideal for Retrofitting Existing Pond Filters

Compared with smaller K1 media, K3 features a larger wheel-shaped design that can make it easier to configure and manage within suitable existing filter bays.

It is particularly useful for pond keepers looking to upgrade or adapt an existing biological filtration system.

Always ensure the filter chamber is suitable for K3 media and that the media cannot escape through the filter outlets.
