Biohome Maxi Ultimate is essentially the large Biohome Ultra with added trace elements to increase bacteria performance and has a porosity of approx. 50%. You can check out the extreme porosity of the Maxi Ultimate yourself by touching just the tip of a piece media to the surface of some water. You’ll be amazed at how fast the water is drawn up the entire length.

Biohome Maxi Ultimate is made from industrial grade material to ensure a long working life. Long working life and reliability are hallmarks of all Biohome products and used correctly Biohome Maxi Ultimate will outperform all other filter media in the removal of ammonia, nitrite and nitrate. Complimentary filter starter balls are shipped with each order.

Maxi Ultimate is an efficient biological filter media and good mechanical filtration must be provided to insure the water passing through it does not contain any debris that might clog it and reduce efficiency.

It is most suitable for aquarium sumps, and shower / trickle filters.

Biohome Maxi Ultimate allows both nitrifying (aerobic) and denitrifying (anaerobic) bacteria to grow on and through it’s unique structure.

Trace elements added include: Titania, Alumina, Ferric Oxide, Lime, Magnesia, Potash, Soda, Phosphorus Pentoxide, Chromium Sesquioxide, Manganic Oxide, Zirconia, Hafnia, Zinc Oxide, Barium Oxide, Strontia, Stannic Oxide, Sulphur Trioxide.

The trace elements are fused into the structure of this media and are there to enhance bacterial processes only, not to alter water chemistry.

This media is sold by the kilogram. 1 kilogram of media is approximately equal to 1.3 cubic litres.

For best nitrate reduction use approx. 1kg per 100 litres aquarium water and 1kg per 150 litres of pond water.
