Are fertilizers needed with a Bio-Home filtration system?

Recently I've been looking at a new shower-head filter by AE Shop that uses a trickle down water effect on seperate boxes of mechanical and biological filtration medias(it looks a lot like those DIY ones on YouTube). I've been reading up on it and I'm seeing that these biological filters will completely remove both nitrites and nitrates, which is supposedly supposed to help plant growth. Theoretically, then, would fertilizers of macro/micro nutrients containing nitrogen elements not be needed, as they would subsequently just be filtered out by the medias?
Lots of love~~~

Plants need a source of nitrogen in order to grow.

Filters dont remove nitrATE, only nitrite. Anaerobic bacteria will remove nitrate, but you need to actually try to get it to grow.

Now this question made me curious.....does Bio-Home media remove Nitartes as they claim?

No. It is being promoted as some 'miracle' product when it isn't. How does it remove nitrates? Does it do water changes for people? If that wasn't bad enough, they are also telling people to overstock their tanks.

BEST FILTER MEDIA ON EARTH ! Perfect for Saltwater and Freshwater Aquarium even outdoor Pond.
1Kg is good for 3000 liter of freshwater and 1500 liter of salt water (3.8 liters= 1 gallon)
Benefits of using Biohome BIOHOME is a unique blend of sintered glass, for use in biological filtration units BIOHOME is the EASIEST, SAFEST and most COST EFFECTIVE Biological filter media available and has these distinct advantages over every other form of biological media
Microscopic tunnels and voids allow billions of Nitrifying and Denitrifying bacteria to live throughout its mass. (Bacteria have shelter but can still access water and food )
Biohome sintered glass is inert and doesn't release any residual gas or toxins into the environment ( It can't poison your fish )
Compact Biofilter will allow you to keep more fish in a smaller tank.
Smaller Biofilter unit is inconspicuous in your home.
Biohome costs you less than other forms of Bio-filter media because you need so much less.
Reduces the need for you to change water significantly.
With adequate pre-filter BIOHOME will give you a long service life.
BIOHOME Significantly reduces toxic nitrogen compounds including Nitrate.
BIOHOME media can easily be transferred between Aquaculture systems
Promotes vibrant health in your aquarium.
Bacteria grow quicker on Biohome because the surface is hydrophilic and allows Bacteria a better foothold than hydrophobic plastic mediums.
BIOHOME is suitable for all Aquaria including Cold water, Tropical, and Marine applications

Aquaculture groups and Governments throughout the world are seeking ways to make fish farming more environmentally friendly, because they have realised the former methods of raising aquatic organisms is not sustainable in the longer term.

Fish farmers can not expect to continually add nutrient to the area surrounding their fishfarm, without a devastating impact on the natural environment. It is ridiculous to condone this practice whilst banning the discharge of nutrients into our rivers and lakes, from primary and secondary industry and agriculture.

Biological Filtration is one of the most essential components of an efficient re-circulating system in aquaculture or an aquarium, whether it is a fresh or marine environment, a Biofilter is still required to remove, Ammonia, Nitrite, and Nitrate.

A enclosed system must have a biological filtration system of some type to maintain water quality, otherwise it will only be able to maintain water quality for short periods, and the water which is discharged is not suitable to support aquatic life. This may also be the case with some Biofilters which are inefficient. Inefficient Biofilters are also not environmentally friendly.

Bacteria ( Nitrosomonas and Nitrobacter ) live on surfaces in the aquatic environment and compete with Algae for Ammonia, Nitrite and Nitrate as a food source. Without these bacteria, the Algae would quickly over-populate the environment and although during daylight hours they enrich the water with oxygen, at night they can remove all the oxygen from the water.

If Algae dies in large numbers in a re-circulating system, or partially re-circulating the aquatic environment, fish kills will occur, because decomposing Algae release an enormous amount of toxins into the system.

Water without oxygen can not support fish or other aquatic life, and all fish and other organisms such as crustaceans would die. Therefore the removal of the Algae food source is usually a very positive step. (Green water hatcheries or systems specifically designed for Algae production are not included here)

Aquaculture systems are using re-circulation system technology are more efficient and impact much less upon the environment . However to use this technology effectively requires an efficient method for the removal of toxins.

BIOHOME IS THE MOST COST EFFICIENT METHOD AVAILABLE TO REMOVE TOXINS WITHOUT UPSETTING WATER QUALITY, (including mineral balance), OVER EXTENDED PERIODS, AND REQUIRES VERY LITTLE ENERGY USE, AND MAINTENANCE, TO KEEP OPERATIONAL.

Anaerobic bacteria, which biohome media can colonize, is what 'removes' the nitrates.

Sorry but even the makers of Biohome say it does nothing for nitrates. Here is information on media that has proof it does nothing.
Full test of 'denitrification media' is here.

Very interesting stuff, thanks for the article. Where do the makers of biohome say it does nothing? I went onto their website and the first thing I see is
"The most efficient biological filter media that supports aerobic and anaerobic bacteria that clears your water of ammonia, nitrite and nitrate that would harm your marine life."

Simple email to Great Wave Engineering that says they have no proof it does anything. Go ahead and email them yourself. However you have read the proof that it does not do what it says. Show me any research paper, study of where this crap and rocks from matrix do what they claim. There is none. Any company can claim anything they want for sales.

Just shot them an email, thanks for all the information. Curious to see their reply if I get one.

Great. We'll compare emails...

At this special time in history, is there any doubt that we all need to check and double check anything we read?
And that goes double for the folks who are trying to tell you that they have special inside information that most folks don't know!!

Here is their response:

Great question. Wish I had better answers. I'm working with some high school engineering and biochemistry students in Kentucky and this was one of the projects I suggested for them, so I hope they'll do a good study.


But, for now all we have are dozens, if not hundreds, of reviews claiming reductions in nitrates. Some of these I take with a grain of salt. Those are ones that claim their nitrates are zero after a week. I'm a little sceptical, but of course I have no idea what sort of tank they have.


On the other hand, I've also seen reports that after a number of weeks or even months they've seen their nitrates reduced to 10 or 20 ppm. Now once again, there is never a great deal of detail so I can't know what their tank is like, but this sounds much more realistic to me.


I started this business about six years ago because I wanted to use the media in my Koi Pond Filters that I was hoping to sell at the time. I never did sell any containing Biohomeģ, but all of my personal filters are running on BioGravel.



I have two filters on my 5800 gallon koi pond that run a total of 84 kgs of BioGravel. These never reduced my nitrates which ran at 100 ppm for years. Of course this wasn't really too big a surprise since a pond of that size needs about 150 kgs of Biohome to achieve nitrate reduction.


I eventually added two Shower Filters holding 150 kgs of SuperBioGravel. This reduced my nitrates to between 30-40 ppm. I'm now using an RO system processing the pond water and my nitrates are running at about 25 ppm so I've taken down the Showers. We'll see if that affects the nitrates.


So I'm fairly confident that Biohome does reduce nitrates when an appropriate amount is used in accordance with our recommendations. We have found that water conditioners which also bind ammonia, nitrite and nitrate, which is most of them, conflicts with the bacteria that does the job in Biohome. In general, other chemical treatments and media can also stop the process.


In six years I've had probably five or six customers claim they were not able to get nitrate reduction. We've always provided these individuals with information about the amount required and cautioning them about water conditioners or other chemicals that might stop the process.


Unfortunately, I can't recall any of these that have responded one way or the other whether our advice allowed them to eventually achieve nitrate reduction. I did receive quite a detailed report from one customer that found that carbon dosing definitely improved nitrate reduction with Biohome. You can see her report here:

Hope you found this helpful. Thanks for your interest.


emailed ended, my thoughts:

I'd say I'm pleased but at the same time skeptical. As you said, it's definitely anecdotal. It neither proves or disproves the saying that biohome removes nitrates. In the end, it seems like it's a better idea to just get a normal, cheap media (I've used seachem biomax with great success, it handles a hell of a bioload and it's cheap), keep up on your water changes, and add plants if possible.

I don't know what you're trying to get at here?
