More info from Dr. Franco in Italy and testing he did

This little section of Koi blog was taken from site in Italy. I have found that it is better to just Google “Filtro Anossico” and then click on translate and then the whole site will be translated into English. Not good English, but readable English for the masses. 

Lio Fornellino AKA: Dr. Franco and his associate Jimmy went through a lot of trouble testing the Anoxic Filtration System for the hobbyist. 

”QUOTE from another Koi site from Dr. Franco: 

Well I'm back with some news: 

2)    Italy is rising with anoxic filtration. This picture is from a meeting done at my house last week. 

All people around now want to try anoxic filter after mine results. 

2) I have now 8000 liters pond with 30 (!!!!) Koi from 40 to 55 cm sized, 28 biocenosis pots (11”x11”) in the filter and a prefilter done by me. I don’t know the name in English language but is similar to Trammel filter and use 20 micron synthetic tissue to stop debris. It’s an automatic washing system. Water is clear and ammonium 0,1 feeding a lot 2 times a day. 

Thank you Dr. Novak

Here is the Trammel filter sitting by the side of the testing pond.

This is a photo of  the Trammel filter that Dr. Franco is talking about.

Stay tune guys for a new test about speed in eliminating ammonium from a tank done with many filtration systems. 

Here are videos of it in action:

I have been trying to get Dr. Franco to come on this site; will see what happens in the near future. 

For those that are reading this, this site may help you understand through testing about the Anoxic Filtration System and what it’s capable of doing. Dr. Franco does not work for me nor do I personally know him in anyway. This is a case where hobbyist are forced to find alternative ways of enjoying this hobby without all the hype and rhetoric that goes alone with the sale of expensive filtration systems that are presently out there. Here in the states I have tested the Anoxic Filtration system to a $45,000 dollar system and the expensive system still was no better than the Anoxic Filtration System. In some parameters the Anoxic System excelled over the more costly system that had a smaller bioload. However, don’t take my word for it, read for yourself the facts from the Italian Doctor’s site about his test. 

Below are some facts Franco gives on his site and are taken from it: 

Many people who have suffered from a pond have to deal with the problems of its management base that is the need to dispose of accumulations of ammonia and nitrite toxicity to fish both directly as a caustic on the skin of fish and especially the delicate parts such as gills, and also because these molecules interfere with their breathing.

After mistakes on errors, they often reach a point where the ammonia problem is at least kept under control.   From here on, nobody cares more than other issues but will later be the source of most of the requests for help from a specialized forum.  NITRATI E FOSFATI . I would refer to two values
​​in a matter of control, as a literature falsely detecting erroneous or simple ignorance of basic mechanisms of fish physiology: nitrate and phosphate.

The small amount of people that these values
​​are measured in faith to the test that will measure both in terms of the value obtained from the tests, both in terms of tolerance levels of fish to these substances.

It’s easy to note that already on the latter there is a different grading scale, so some companies identify as a dangerous dose of 150 mg / l of nitrate, others are alarmed at only 50 mg / l. Non diversamente avviene per i fosfati. not unlike the case for phosphate. The same traders who have over time sectarianized trade of aquariums for example, refer intolerable even small amounts of phosphate, while other retailers do not even recommend testing for phosphate as one of the important ones.

It 'obvious that these two substances such as ammonia and nitrite are the threshold doses above which death is certain for the fish.  The problem is that there is an absolute value beyond which they are surely harmful substances even if the danger threshold of ammonia and nitrite is significantly lower than that of the other two molecules. The truth is that the fish can easily do without all these four substances (ammonia, nitrites, nitrates and phosphates) and the concentration of fish in the wild puts them in the condition that they are not ever in contact with even tolerable levels of same (in kind is very difficult for a carp live in an environment that is higher than 1-2 ppm of nitrate).

It’s very easy to find a pond with ammonia and nitrites under control, which also have unsuitable levels of nitrate and phosphate. Industrialization and the need to remove the residues of processing factories, along with a lack of control of the territory by the competent bodies has allowed for decades to dispose of these substances easily as easier and less expensive for those who produce, that is poured into rivers or lakes.

Today the fish around the world are thus facing the need to adapt to the values
​​of water contaminants that select resistance.  In some cases, it also comes to environmental disaster where the expense to the fish to animals that come in direct contact with those waters.  The news has even used to help include events that reach even our health, for direct consumption or indirectly (irrigation of crops) of contaminated water.

Yet in a pond with almost zero ammonia and nitrites, nitrates and phosphates low or almost non-existent, we are witnessing one of the most common in our ponds: water green and cloudy for exponential growth of single-cell algae, with the edge of the lake and its decorations (rocks or gravel bottom) exposed to the plague of algae or flowing hair. This is known as eutrophication and is generated primarily by phosphate abundantly used in agriculture, but also in different chemical conformations in domestic wastewater for the use made of detergents.
To resolve this problem, many find satisfaction in the use of products (chemicals), which have only a partial result: they act on single-cell algae through a process of flocculation and leave unresolved the problem of those streamers.  Are to be used regularly, but if the pond is large-size, the cost of this "solution" becomes a financial commitment.

Of course, in addition to chemical methods for solving the problem there are also those for irradiation of UVC rays but only solve the problem of purity and leave intact the algae problem in string (streamers). Then, much used in England, is the "solution" with barley straw placed in cloth bags in the pond and left to work a few weeks.  The bacteria that metabolize eliminate hydrogen peroxide (H2O2: hydrogen peroxide) as a byproduct of metabolism, it is toxic to algae, but there is still no clear feedback on the possible danger to fish.

What is certain is that these systems do not solve the root problem.
But what is the root? ...... ...... Simple!  Phosphate continues to occur and the possibility of recycling is not constant.  Alga needs four things to live: High heat, sun, phosphates and nitrates. The complete lack of a single "ingredient" is to fail the "cake recipe." The sun, as a pond can be repaired, it is still exposed to it for a few hours of the day.  Water temperatures for outdoor ponds are poorly managed by the user who often assists at elevations up to 30-32 ° C.  Nitrates and phosphates can be rather "cancel".

The challenge is to understand what it means to cancel! I have a pond with algae! . First tests for nitrates and phosphates and give me both virtually non-existent, I have a pond in semi shade throughout the day, but early in the spring, so even modest temperatures, witnessed the phenomenon of algal bloom.  From that moment on, I cannot get rid of the algae problem for the rest of the hot season.

As a pond cannot "pretend" to have algae then I believe that the tests are flawed. Ed in parte รจ vero! And in part it's true! Phosphates can be found in the water as orthophosphate, polyphosphates and organic phosphates. The reaction used for the analysis with standard tests is specific for orthophosphate, if you want to determine the phosphate present in other forms should be a pre-treatment sample.

You must then multiply the result of a test for nitrates to 4.43 to obtain the real concentration of nitrate in water.  The Filter works by reducing Anoxia, even avoiding the production of such substances as ammonia molecule acts directly on removing it from the various stages of the process known as nitrification, another larger process known as the nitrogen cycle.


The nitrogen cycle is defined as the process originating from the excrement of the fish, into nitrate (through the passage in which he is first and then ammonia, nitrite), which is absorbed by plants as food. This reasoning, which is the basis of the management methods of our ponds, it is not correct in all its parts.( ). The belief that with nutritious plants prefer nitrate, in recent years is giving way to different evidence: plants prefer ammonium ( / plants_and_biological_filtration.htm ). The plant uses the nitrate in it only after it transformed into ammonia.  This reduction process is the mirror of the nitrification process operated by the bacteria.

NH4+ + 2 O2 >> NO3- + H2O + 2 H+ NH4 + + 2 O2>> NO3-+ H2O + 2 H +

This process generates energy corresponding to 83 kcal / mol.  The opposite procedure, operated by the plant, is subject to a cost because it requires energy to achieve (the same as 83 kcal / mol).

NO3- + H2O + 2 H+ >> NH4+ + 2 O2 NO3-+ H2O + 2 H +>> NH4 + + 2 O2

The plants then uses nitrates only if it has more ergonomic alternative dates by the presence of ammonia.

The conversion of nitrate to ammonia which is also outside the plant by bacteria in two series of reactions known by the name of:

- DENITRIFICAZIONE ASSIMILATORIA - Denitrification Assimilator

It uses bacteria that work closely in anaerobic environment (bacteria obligate anaerobes) which through two steps transform the nitrate nitrogen (NO3) first in nitrous oxide (NO2) and then to ammonia nitrogen (NH4). Only 4-10% of ammoniacal nitrogen is converted to bimolecular (which is released as a gas). The remaining 90% is produced by a process called denitrifying.

This process involved facultative anaerobic bacteria called bacteria, which can live in that environment is oxygen rich than poor in oxygen. In oxygen-rich environment that directly use dissolved in water as an electron acceptor in cellular reactions in oxygen-poor environment that is collected through the reduction of nitrate to nitrite and then ammonia.
The response made
​​by these bacteria is that which occurs in the Anoxic Filter.
