Biohome Ultimate is most suitable for canister filters, overhead filters, large HOB and small shower / trickle filters. It has added trace elements to increase bacteria performance and has a porosity of over 50%.
 
You can test the extreme porosity of the Biohome Ultimate yourself by touching just the tip of a piece of 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.
 
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, and 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 first to ensure the water passing through it does not contain any debris that might clog it and reduce efficiency.
 
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.

All types of Biohome media are made from industrial grade materials to ensure a long working life. Long working life and reliability are standard hallmarks of all Biohome products. Biohome media products allow both nitrifying (aerobic) and denitrifying (anaerobic) bacteria to grow on and through their unique structure.

Do not worry about plant growth being affected in a tank which reads zero nitrates - the nitrate is processed into soluble nitrogen which is easily used by plants, boosting their growth.

Avoid using 'chemical filtration' products such as Purigen when establishing a filter as there seems to be a link between using some chemical treatments and failure of bacteria populations, especially anaerobic bacteria which can be wiped out by unnecessary chemical treatments. If you want to draw in colour from water or residual fish treatments use carbon as it will not kill bacteria.

For best nitrate reduction use approximately 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).
