Biohome ultimate is most suitable for canister filters, overhead filters, large HOB and small shower / trickle filters. It is essentially the Mini Ultra with added trace elements to increase bacteria performance and has a porosity of over 50%. You can check out the extreme porosity of the 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.

As the name suggests Biohome Ultimate is the pinnacle of filter media design and strikes a perfect balance of size, strength, surface area accessibility and specific trace elements which ensure that it will outperform every other filter media for the removal of ammonia, nitrite AND nitrate

Biohome Ultimate is made from industrial grade material to ensure a long working life. Long working life and reliability are hallmarks of all Biohome products.

Biohome 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.

Biohome 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 allows both nitrifying (aerobic) bacteria for reduction in ammonia and nitrite and denitrifying (anaerobic) bacteria for reduction in nitrate to grow on and through it’s unique structure.

This media is sold by the kilogram. 1 kilogram of media is approximately equal to approx. 1.25 cubic litre.

For best nitrate reduction use approx. 1kg per 100 litres of aquarium water for a normally stocked tank. Heavily stocked systems can take between 1.5kg - 2kg per 100 litres to achieve full cycle filtration (reduction in nitrate).

As all Biohome media is inert it allows you to raise or lower the pH to suit certain fish species without having a buffering effect.

Free gel filter starter balls are shipped with every order - simply add them in with the media in your filter and they will slowly dissolve, helping to seed the filter naturally and very effectively with live bacteria.
