Aqua Max Bio Filter — 25 Litres

Biological filter housing for koi ponds and aquatic systems. Bio filters contain living bacteria that break down harmful ammonia (from fish waste) into nitrite, and then nitrite into less harmful nitrate. This is the 25-litre unit — requires 335 bio balls (not included) to fill the filter chamber.

Important — Koi Pond / Aquatic Use

This is a biological filtration component for ponds and aquatic systems, not swimming pools. It works alongside mechanical filtration (sand filters) to maintain water quality for fish.
