Filter Media pack to suit most canister filters. Comes complete with 40 Bio Balls and 500g of ceramic noodles.
Ceramic noodles are highly porous and provide the ideal environment for beneficial bacteria to grow on. Bacteria are necessary in the filtration process and the ceramic noodles act as a Mechanical/Biological filter. Large waste particles naturally created by excess food and faecal matter in your aquarium are caught and ingested by the bacter therefore, removing and reducing the potential toxicity of the waste.
The advantage of bio balls is in their ability to not only be very effective substrates for nitrifying bacteria, but also in their unrivalled ability to oxygenate the water.
