On the garden site, giving from normal pond the excellent composition which will recover and will decorate any estate can turn out. But such beauty needs continued support - without good leaving the reservoir can turn into musty pool.
Requirements to purity of water in ponds have considerably raised. If in pond at the dacha there is a wish to breed more fish, water is required to be changed more often, and this process is rather labor-consuming. Water can be purified with application of systems of mechanical and biological cleaning. In the first case the filters help to delete small seaweed and dirt. Such device begins to do the work at once after it is turned on, it can be started as required. At biological cleaning completely different task.
At such approach being on the filtering surface of system of biological cleaning of bacterium, seaweed and invertebrates carry out all necessary work - that is process the died-off remains of plants, sterns which was eaten by fishes, other garbage in absolutely harmless connections. Each of filters should be washed out in due time - as it is specified in the enclosed documents. Ponds at the dacha can be cleaned in two ways - that is mechanical or biological.
Biological way of cleaning
Biological cleaning is more difficult. It can be applied also in ponds, big by the size, and in small. Filters establish out of pond. From artificial reservoir water forcibly comes to the filter, is aerated and consistently there pass several drainage courses. To fill such filter, special granules, polyfoam, the rubberized bast mat, coarse-grained sand, gravel are applied. The first of drainage courses carries out preliminary cleaning and at the same time performs work on mechanical cleaning of water. All subsequent layers carry out cleaning biological. The water purified thus is returned to pond spontaneously - the pump have above, than height of water in reservoir.
Ultra-violet water treatment also belongs to cleaning species. The filter is installed out of reservoir and consists of the camera for water, the body and source of UV-radiation. Such way of water treatment is necessary because some species of seaweed so small that can pass through any of filters. In this case ultra-violet cleaner is also useful - it is the newest of devices for water cleaning. From the filter water passes into the separate camera where at influence of ultraviolet of cage of seaweed are destroyed.
Mechanical way of cleaning
Cleaning mechanical is way not less effective and not especially expensive. The filter is placed in water (she moves not in the compulsory way). Water after passing through cellular material, coarse-grained sand, gravel through pipe arrives to the pump and cleaned is returned to pond. If it is a little fish in pond, water quality good, under water there are enough plants, in use of the filter of special need is not present. But some species of fish can breed very intensively, and soon improvement in the form of additional filtration can be necessary.
Allocations of fishes and remained not eaten forage saturate water with nitrates in such quantities that becomes insufficiently simple biological self-cleaning. If the pond is located in such place where it is strongly lit by the sun, and plants which can create shadow, a few, reservoir will need filtration. The water is warmer, the smaller amount of oxygen contains in it. The filter will level in addition temperature of top layers of water which are heated by the sun, and lower. Together with water enrichment the underwater filters can serve fountain, small cascade or the figure supplied with small fountain. Their work will be noise-free and reliable.
Many of the systems of filters perfectly work and have proved the durability in practice, and the devices developed by national handymen which can be built the hands turn out is not worse at all.
