1) HOW DO I HAVE THE LITTER AND LATERITE IN THE BASKET AND BASKET FOR EVERY AS NEEDED?

The laterite is all divided into small piles of equal weight (about 385g) according to the number of baskets that you have to fill in, then the baskets are filled up to 4 cm from the top and should be given with your hands a depression in the center. You must enter the laterite in the depression and should be covered with litter (always supplied in adequate quantity) to standardize the level with that move.

Finally should be placed pebbles (quarry) by 2-4 cm above the litter coming up to completely cover the top edge of the plastic basket.

2) The BASKETS ARE MADE DIRECTLY IN THE POND?

The litter basket contains a fine powder that must be removed before the introduction of baskets in the pond (the risk is that the color of brown or grey aqua). To this end it is sufficient to immerse every basket a couple of times in a basin containing water, dripping after a few seconds can be introduced into the filter.

3) CAN BE COMBINED ANOXIC FILTER TO AN EXSISTING FILTER FOR MY ABILITY TO INCREASE THE 'FILTER?

No, the nitrification filter produces classic, starting from ammonia, nitrite and then nitrate in a process called "nitrification", which is part of the "Nitrogen Cycle", while facultative anaerobic bacteria use their ability to process ammonia directly when they find it as such, but must convert ammonia to nitrite and then if the nitrogen comes in the form of nitrate, they must do the exact opposite route.

This subjects the bacteria to more metabolic work which slows down the unique ability to use ammonia directly.

If you want to go during the hot season, a filter to a classical filter anoxic nitrification, as a precaution and only you can do initially coexists two types of filter, taking care to place the filter before the anoxic nitrification and not the other way. If the replacement takes place over a period of quiescence of the filter (winter), the substitution can be so fundamental without risk to the fish.

4) HOW LONG WILL IT TAKE TO BE THE FILTER Anoxia 100% efficient?

In ponds already built and launched it takes about 20 days. In lakes started, where initially they coexist (for security reasons) two filter systems (anoxic nitrifiers and classic), the activation time may be considerably longer, but not more than 50 days.

5) I CAN MAKE A FILTER Anoxia And Add The Laterite Later?

No, the laterite plays an important role as a mineral deposit to which the bacteria facultative anaerobes draw for their optimal development and replication. The laterite is a mineral rich sediment of many substances used by bacteria for their metabolism such as iron hydroxide, iron oxide, zinc, copper, manganese, cobalt, kaolin (which is a white clay containing aluminum oxide, titanium oxide silicon), traces of inorganic elements, just to name a few.

6) I CAN MAKE A FILTER WITH A LITTER Anoxia DIFFERENT FROM THAT PROVIDED?

Dr. Novak has spent more than 20 years to test an infinite amount of clay that may have an effect similar to that of clay litter. None of those tested has the characteristics of porosity and permeability of this. Dr. Novak for the realization of the anoxic filter has previously rejected as bentonite clay, montmorillonite, kaolin, Uras, Illite, sepiolite, attapulgite.

7) DO I PUT THE BASKETS ON THE BOTTOM OF THE POND FILTER DIRECTLY?

No, the filtering capacity of the basket depends on water that passes close under the action of a water circulating pump. At the bottom of the pond baskets would not have enough flow with which to interact to subtract the nitrogenous contaminants.
In addition, the baskets would be placed directly on the bottom soon the subject of curiosity koi who love digging gravel in search of food, the natural consequence of finding the empty baskets and the litter scattered on the bottom of the pond.

8) I CAN PUT THE LITTER RIGHT ON THE BOTTOM OF THE LAKE IN BASKETS INSTEAD storing?

No, the baskets have drilled 6 faces exposed to contact with the water that would not have if you would put directly to the litter on the bottom of the pond. The filtering capacity of the basket Biocenosis would thus be undermined.

9) WHAT IS THE BASKET BIOCENOSICO?

. In ecology the term biotic communities (or communities) is derived from Greek words βιος (bios = life) and κοινος (koinosis = common) and indicates the community of species in an ecosystem that lives in a certain environment, or, rather, in a particular habitat (from the Greek life and τοπος βιος = = place), ie an area in which the physico-chemical and environmental conditions are constant. The habitat, due to its characteristics, can be defined as the fundamental unit of the environment. Wikipedia The ecosystem is made up of biotic and habitat so. Wikipedia

Biocenosis The basket is therefore a unit in which bacteria cooperating in the formation and maintenance of a certain chemical and physical environment and environmental conditions constant.

10) How long do BASKETS BEFORE YOU LOSE THEIR EFFICIENCY Purifying?

The bedding material is a clay fired at high temperatures through which the clay micro-porous structure assumes its importance. Nearly over 20 years of use since it was discovered for use in the anoxic filter has not shown signs of functional decline. The laterite is a mineral rich in trace elements that are used by bacteria for sustenance and ripodouzione. This source is exhausted after approximately 10 years and must be replaced by another new one that is added directly into the basket that contains the old litter.

11) CAN I PLANT UP THE BASKETS?

Yes, the baskets can contain all types of aquatic participant whose capacity is added to that specific filter basket Biocenosis. . Depending on the type of trees planted in the baskets, the water level of the basket to the surface of the lake varies from 2-3 cm to 10-20 cm. The baskets that contain plant given the vigorous growth of the latter, the presence of laterite, be repotted at least every 2 years.

12) HOW TO PLACED THE BASKETS IN THE ANOXIC FILTER?

They can be arranged in several rows side by side and overlapping, making sure to put a spacer between the baskets and the bottom of the filter (of an inch, minimum) and between baskets placed one above the other. Horizontally baskets, given the shape of a truncated inverted pyramid can be matched to each other without spacers.

13) HOW DO I PUT IN MY POND BASKETS FOR HAVING AN OPTIMUM FILTRATION?

The baskets can be of different sizes: 23x23, 28x28, and 32x32 (not marketed them in Italy) would be natural to say to add as many baskets until the water reaches the correct values stability. Since it is never a problem to put more than needed, to put the minimum number depends on the size and number of fish in the pond.

Conventionally, a basket of 28x28 can filter water from the waste produced by an adult koi no more than 40 cm. the calculations for the other baskets are to be calculated on the basis of this finding, and in any case, if the values are not yet fully achieved, it is necessary to add additional baskets.
