Ozone
This is a very different story and is usually only used by hobbyists who keep Koi but it can obviously also be applied to the normal garden pond. In the piece below, a layout will be clearly described on the application and the dangers of ozone.
 

What is Ozone
Oxygen in the atmosphere is around us. Oxygen is a substance that a single molecule of two atoms.
For example, a thunderstorm by the high electrical discharges that are discharged through the air, molecules formed
of three oxygen atoms. This is called Ozone. We recognize this product to the pungent smell fresh after a heavy
Thunderstorm rain lingers a while. The ozone molecules are not stable connection and would like as soon as possible
back to its original shape. They will be asked one of their three atoms to release something else, such as an alga, a
bacteria or other product to oxidize (burn) is. After this oxidation will then pure oxygen.

It reduces:
- E. the germ load of the water, making pathogens fewer opportunities.

Let's go to these points.

The redox potential value (rH)
The redox potential is expressed as the ratio between so-called reducing and oxidizing effects.
So rusty iron in a strong oxidizing (burning) and denitrification can take place in a pond at resort with strong reducing (ie anoxic) conditions. Simply put it can be said that high oxygen levels is associated with a high redox potential. The redox potential (rH) is officially expressed on a scale from 0 to 42, with the neutral point to 21. In practice, they are expressed in millivolts. This practical measurement unit (measured with a special electrode) is based on the phenomenon that a certain flow of electrons in water to measure. The higher this measure fails, the greater the oxidizing effect. Thus, the average pond have a rel is approximately 180-225 millivolts. This is weak oxidizing. In trays, the RH in a heavy population, much lower. If an optimal value rH seen is around 350 millivolts. Where these values through normal circumstances, such as water movement, etc., to reach Ozone is the appropriate product to achieve this anyway.

To avoid mistakes is to use a proper redox meter with control capability highly recommended. RH values too high can be extremely harmful. In theory, with ozone to sterilize the entire pond, including fish life impossible. This can be considered a redox potential higher than 400 mv in the pond water itself, begins to decide harmful for all living organisms in the pond.

The enhanced performance of the biological filter and a rapid oxidation of some wastes. Because the water eventually will contain more oxygen and by the organic load of water through Fri aquatic unicellular organisms decreases (see also count) there is more oxygen on the biological filtration. Ozone also helps a number of intermediates directly convert. Thus, oxidized nitrite to nitrate, causing the bacteria in their work with the file filter greatly relieved.
Ozone can also never replace the filter. For example, certain substances, ammonia and ammonium are the most important, not fully burned in freshwater.

Ozone is only a tool.

Colorless and clear water.
Ozone one hand, the aquatic unicellular greatly reduced. Second Ozone burns the colors over time and formed the pond water can give a yellowish tint. For water with ozone is that when used correctly sparkling water
will be fresh after a few days.

The plate count.
In all ponds sits next to the fish and plant a certain quantity of another life. The total living material, the
called biomass. In a healthy natural environment such as a lake or a river is the total biomass of less than 0.5%
out fishing.

The positive role of plants we know all. The remaining mass from small water creatures, plants, algae, bacteria etc.
exists, is particularly important for a healthy pond. Only we like that as many of those organisms are not in the
free water are somewhere else, as in the substrate and filter. Organisms in the water causing a usually undesirable cloudiness and use excessive zuurstof.Naast the required biomass can also, especially when the conditions are not optimal, pathogens among them. By ensuring that pond water rH has around 350 mv. is, the number of protozoa (and therefore the pathogen) be kept as low, that practically no longer will come when a sick fish to another fish through water infects. In addition, through an optimal water quality, which Ozone is an important tool may be a sick fish have more opportunities to the inherent resistance to build without the negative effects of drugs.

Application
Ozone must be in good and safe to go. To greatest effect of ozone to get into your system, the control system
optimal. Only with a good ozonator you are not there yet.

A. If too little ozone is added to the water will be minimal impact. When there is too much ozone is added, there may arise a poisoning effect, where anyone was served. To check if everything is working properly, you have an ozonator alongside a control device that requires just the right amount of ozone added to the water: namely, a redox potential meter with a built-in switch corresponding to the desired value the ozonator off.

B. Ozone is an ozonator (generator) is formed from air. The effect achieved with ozone should be made only
in the water itself. The best ozonator will not help if we are unable to ozone to where it is needed
which is in the water.

To Ozone from air into water to get an ozone reactor is needed that ensures optimal absorption of ozone in the water.
A good reactor can ensure that 100% of the produced ozone in the water is absorbed and there is no Ozone in
air disappears.

Although optimal skimming in fresh water with the current technology is not feasible, would be a well constructed skimmer based on systems that are used in marine aquaria, as well meet ozone reactor. If there is something even skimmed off (up to about 50% of the waste) is included. Do-it-yourselfers is that the ozonized air for a long time
a reactor in contact with the water should stay at the Ozone in the water to be resolved.
The required amount of ozone. The amount of ozone required for a particular goal, is not determined by the amount of water, but the amount of burning materials. Simply put: not the pond size determines the required amount of ozone, but the amount of food that is administered daily. We have already said that in a healthy natural pond Ozone should not be forced in a normal population. As the population denser, more ozone will be necessary and in ever larger quantities are needed.

Ozone as a normal pond is used solely to keep the pond clear, will be approximately 3-5 mg per 100 liters / hour ample
are. In an eel fattening where 20 M3 3000 kg eel swims, it more than 50 grams per hour ozone used for water
somewhat acceptable quality of love. In a very busy selling proposition in a garden center, the required amount
Ozone per hour per 100 liters of water is around 10-15 mg lie down. There will therefore always a bit of math involved.

Soon what matters in a row.
Ozone is not a panacea. It is good to use a fantastic product support, but no more.
Ozone is not a medicine. It helps to good use or to improve water quality so that the fish are stronger and more resistant opbouwen.Bij an rH of about 350 mv. the chance that a sick fish infects other fish to a minimum.
Ozone, a pond can never be sterile, or weaken the fish. All biological processes are still necessary present.
Again, only enhances ozone, when properly used, the situation. A good effect of ozone is accessible only from a good control
and via a reactor, which guarantees admission to the water.

When used properly Ozone is not harmful. Not for the fish and not the owner. Ozone can easily escape path
filtered through some activated carbon. The often-heard advice to remove residual ozone using an ultraviolet lamp,
is only partially correct. With UVC light of Ozone and water H2O2 (hydrogen peroxide) formed a substance which in large quantities just
so aggressive fish can be as free ozone itself. In an rH of about 350 mv. Ozone is not present in free form and not harmful.

WARNING!
Ozone should never be used in combination with drugs. The effects of the drug will often be shattered
while toxic substances can be formed. It can be stated that drug use will be greatly reduced by the use of Ozone.

Some conclusions:
A good pond must be healthy for the use of ozone is not necessary. In most cases it can be used as an aid to the pond crystal clarity and free of dyes into commerce would maken.Ozon many existing problems can occur. All too little use made of the possibility of ozone to better quality fish to come.
Ozone is only a good product when you know where one starts and where the peripheral functions optimally.
The knowledge to generate results, is there.
