velda Clear Control 25 - Mechanical Action

functions: the water is kept clear by filtration and circulation creates a sufficient
amount of oxygen. The filter can be used for both mechanical and biological
purposes to filter the water. Below a short description will be given of both methods.
MECHANICAL ACTION
The action of a mechanical filter is based on the removal of organic and inorganic
dirt particles and, if necessary, the removal of colourings, depending on the filter
material. In order to prevent the filter material from getting silted up, it should be
rinsed regularly. Normally this is an annoying job, but it can easily be done when
using the Velda Clear Control pressure filter.
BIOLOGICAL ACTION
A basic assumption of a biologically functioning filter is to obtain a better and
quicker conversion of organic components by means of micro-organisms. An in-
tegrated biological filter benefits the general activity of the micro-organisms and
consequently stimulates the growth of the water plants. It is advisable to use a
biofilter when stagnating plant growth, excessive growth of algae or a too large
fish stock in proportion to the quantity of water, are at stake. Initially the filtration
will be exclusively mechanical, however, with the lapse of time, the materials will
become biologically active. You can stimulate the biological action of your pond
by inoculating the filter substrates with a special culture, like Bacterial Filterstart
