Find a productProduct description
This is a 5-litre ceramic biological filter medium in the L size, made for canister filters. It is aimed at aquarists who want a medium with a very large surface area for nitrifying bacteria and a structure that does not shift water pH, in freshwater and marine tanks alike.
Why it matters
- Surface area of 3600 m² per litre, which gives bacteria a large colonisation area in a limited volume.
- Neutral effect on pH, which the supplier states is maintained at 6–7.
- Pore structure is described as improved over the previous generation, intended to let the bacterial colony develop faster.
- The QUAD cross-section is intended to improve flow and stability inside the filter.

Frequently asked questions
Size L is intended for bucket-type (canister) filters. The package contains 5 litres of ceramic media, supplied as five 1-litre bags, with a total weight of 3.84 kg.
According to the supplier, it is pH-neutral and keeps water at pH 6–7, so it should not acidify or harden the water. A separate SOFT variant is offered for gentle pH reduction.
Each package includes five sachets of nitrifying bacteria, supplied at no extra cost. The media itself comes in five 1-litre bags.
The supplier describes it as an improved version of PURE with a better pore structure, a wider variety of pore sizes for bacterial colonies, and a longer service life. It is also stated to have 3600 m² of filtration surface per litre.
The supplier states that the QUAD cross-section, with its cross-shaped profile, improves water flow and stability inside the filter.
