Biohome is known as a 'SINTERED GLASS' media as it is mostly constructed from special sand. This material is colonized much faster than 'CERAMIC' media which is made from clay.The 3D shape with the highest surface area per volume is a sphere. Imagine the media made from thousands of tiny spheres, all different sizes. That is Biohome.Biohome has been around for approximately 15 years but has been mostly sold in the Far East where keepers of Koi and Arowana appreciated its remarkable ability to process the waste generated from these demanding species. Biohome Ultimate Media is the ultimate media for canister, HOB and sump filters.1 kg occupies about 72 cu in. To see how much your filter requires return to the Home page and click on the link at the top, Biohome Ultimate is identical to Mini with the addition of trace elements, including iron and maganese, to support beneficial bacteria growth. Bacteria growth in Ultimate is very fast to control ammonia and nitrite.Complimentary Filter Starter Balls (1/4 bag per kg) are shipped with each order to speed filter maturity. It recovers quickly after the use of medications.Biohome allows both nitrifying (aerobic) and denitrifying (anaerobic) bacteria to grow on and through it’s unique structure. This allows it to also control nitrates. Ultimate Media is a 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.Please let us know if you have anyAs the Asian market tended to be skewed toward large tanks or nano systems the available forms of Biohome (Standard, Plus and Ultra) were perfect for many of the fish keepers there but the UK and US is different. Although extremely popular, fish keeping in UK and US tends to have many more 'average size' aquariums of between 100-300 liters capacity which are typically filtered by external canister filters.As the extreme porosity of the ultra media is perfect for supporting aerobic and anaerobic bacteria in higher flow rates Richard suggested that the Ultra be made in a smaller form making it more suitable for use in the trays of external filters and 'Mini Ultra' was created.With the combined knowledge of the biohome manufacturer and a chemist the perfect balance of size, porosity and performance was achieved resulting in the revolutionary Mini Ultra media which allows the full nitrogen cycle to be completed inside an external filter. A later improvement to the mini ultra (addition of trace elements for benefit of bacteria) resulted in Biohome Ultimate which allows for even faster bacterial colonization and faster processing of ammonia, nitrite and nitrate.Through years of Biohome being used in all sorts of aquariums and ponds the recommended amounts of Biohome needed to see a good reduction in nitrate (full cycle filtration) are as follows:
(100 liters is approx. 26 US gallons and 1kg = 2.2 lbs)
Average community tropical aquarium = 1kg per 100 liters
Average coldwater aquarium = 1kg - 1.5kg per 100 liters
Goldfish aquarium = 1.5kg - 2kg per 100 liters
Predator aquarium = 1.5kg - 2kg per 100 liters
Large cichlid aquarium "Discus" = 1.5kg - 2kg per 100 liters
Malawi / Tanganyikan aquarium = 1.5kg - 2kg per 100 liters
Marine aquarium = 1.5kg - 2kg per 100 liters
Average mixed fish pond = 1kg per 200 liters
Average koi pond = 1kg per 150 liters
Ammonia and nitrite will be reduced at much lower amounts but full cycle filtration is the only 'proper' filtration therefore the figures above are for the filtration job to be done properly resulting in more stable water conditions. REMEMBER - It is always better to over-filter than under-filter as a filter with a larger capacity will react more quickly to any pollution incidents and process waste before levels rise above safe amounts.
Having filtration capable of reducing ammonia, nitrite and nitrate reduces the need for water changes, allows for pH reduction and creates a much more stable environment than is possible with any other media.
Now there is a form of Biohome for every filter application and as Biohome is manufactured from sustainable materials (sand, trace elements and recycled glass) it is environmentally friendly, inert, allows for pH increase / reduction if necessary and will easily last 6-10 years at high efficiency in a properly set up filter.
You will not find a more environmentally friendly, efficient and cost effective media anywhere else.
