The nitrogen cycle in an aquarium or pond is all about the bacteria and how it processes ammonia to nitrite then to nitrate. Most filters stop there and the nitrate is not processed as that relies heavily on anaerobic bacteria which almost all available filter media cannot support. Biohome is different as it allows for good anaerobic bacteria colonisation as well as the more common aerobic bacteria. Therefore it completes the Nitrogen cycle.
Biohome filter media has a massive surface area for aerobic bacteria colonisation and also has a great capacity to provide an environment for anaerobic bacteria on the interior of the media.
Hugely porous and extremely efficient, the Biohome media converts ammonia and nitrite (as normal media would) but also reduces nitrate due to the anaerobic bacteria which live in it's core.
This reduces the need for large water changes so creates a more stable environment in your aquarium (freshwater and marine) and pond.
It is inert and will not release any chemicals / minerals into the water but it is advisable to rinse before use as dust may be generated during transit.
Types of Biohome media are as follows:
1 - Biohome Standard
A compact media suitable for overhead filters, trickle filters, sumps, external and internal filters.
2 - Biohome Plus
As above but with additives to ensure much faster colonisation by bacteria.
3 - Biomotion
A rounded media with neutral buoyancy. Suitable for moving bed filters, overhead filters, trickle filters, sumps, external filters and internal filters. Has montmonrolite clay coating to condition water.
4 - Biohome Ultra (large)
A larger version of Biohome standard with rougher feel. Extremely porous. Suitable for trickle towers, sumps, larger external filters, overhead filters and multi chamber koi filters.
5 - Biohome mini Ultra
A smaller version of Ultra, perfect for external filters, sumps, overhead filters, trickle filters and internal filters. Has the ultra porous structure in a more convenient size. 
6 - Biohome Ultimate*
This is Biohome mini Ultra with added trace elements (as in biohome Plus) which are essential for bacteria to rapidly colonise a filter. Cuts down the already quick maturing time of Biohome media and has the ultra porous structure and convenient size of Mini Ultra. 
Trace elements in 'plus' and 'ultimate': Silica, 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. (from XRF analysis)
Is this the best filter media ever? Very likely. 
*In the UK the Biohome Ultimate is my exclusive product and has been made to exact specifications making it the 'Ultimate' filter media and ending my search for the best filter media.
Feel free to share this video anywhere you think people may benefit from it - especially on forums as I see so many poor videos on the Nitrogen cycle where they just stop at the Nitrogen production point.
