Aquael Naturemax BIO – 1 litre biological filter cartridge

This 1 L biological filter insert is for aquarists who run internal or external aquarium filters and want a biological medium that does not shift water chemistry. Its lightweight, microporous structure is meant to host nitrifying and denitrifying bacteria in the filter.

Why it matters

• The microporous structure gives bacteria a surface to colonise, which the supplier links to removal of ammonia, nitrites and nitrates from the water.
• The medium is natural and, according to the supplier, does not change pH, kH or GH, so existing water parameters stay as they are.
• Its low weight means it adds little mass to the filter, which makes servicing easier.
• The material is durable and does not break down. It is cleaned by rinsing in aquarium water, and the supplier recommends replacing about 50% of it every 4 to 6 months.
