Biohome Ultimate (3kg)


Suitable for freshwater and marine (optimized for freshwater)

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.

Brilliant service

Richard your a star mate, ordered yesterday and delivered today, even managed to change my order at the very last minute, will be setting up my new filter system at the weekend. By all the previous reviews, this will eventually sort my Nitrate problems out, thanks again

Best filter matrial ever

I have many aquariums for over 30 years, 1 year ago I watched youtube with this matrial Biohome, and when I had just bought a new 450 liter Juwel aquarium with a built-in filter yes then Biohome had to be tested.

I removed Juwel´s filter curve and filter matrial and filled the filter with Biohome and now a year after it stil runs without any problem, the best filter matrial i have ever treid.

Can be higly recommended and only 1 week delivery from UK

Blackwater Experience

I somewhat skeptically purchased Biohome Ultimate in July 2019 from GreatWave in the US. I've been using it in a blackwater tank (i.e. heavy tannins in the water) with snakeskin barbs and corydoras and I confess that it seems to be working rather well. (1.5 kg Ultimate in an Oase BioMaster 350 for a 20 gallon tank.) I was wrong to be skeptical and recently bought more. My nitrates are very low despite full stocking and regular feeding via auto-feeder. One point that others might find helpful is that I use it with Seachem's "Renew" product which is essentially a less aggressive form of carbon that helps clarify the water but does not remove the tannins. Relative to the cautions on this and the GreatWave engineering web site about avoiding carbon, Purigen, Chemipure Elite, and other such chemical filtration, I've found that the "gentle" less aggressive Seachem Renew is providing the clarification I want without impeding the so called full cycle. Another point that others might find helpful is that I'm using some of the liquid blackwater extracts --some of which have glutaraldehyde in them as a preservative. Naturally, this reduces algae but I also wonder if the so-called liquid carbon aspect helps establish the full cycle as some have suggested. So far so good. Lastly, thanks to Richard for the YouTube efforts, especially the ever delightful, "Pimp My Filter" Series.

Superb kit, nothing beats it

Exceeded my expectations, very low ammonia and nitrate spikes during initial maturing and now undetectable nitrate too. Very happy.

Thee best media out there.

Does exactly as described outstanding performance.

That's my tank sorted for 10 years at least.
