Moving sand filters

For additional biological assets

Due to problems with very large quantities of fish that asking too much of an existing filter, it is very common for a filter to be replaced, or the conventional manner to be extended. But often neither feasible solutions because there is not enough room (or money) is present. In such cases the cost Moving Sand bed filter into its own and can - assuming that the mechanical filtering by the present system is sufficient - for a large and clearly discernible improvement in water quality concerns.
Moving Sand bed filters that extreme biological visdruk cope is already extensive and clearly defined and so are the problems with wear and short life span of these filters on the market earlier. Cloverleaf has now - after extensive field and laboratory - the best of the best in the area of ​​Moving Sand bed filters in its range. And that's mainly due to the unique characteristics of the particular silica sand used. It has been scientifically shown to be a lot better than allowing colonization by bacteria coral sand and other species. By comparison, research has shown that the unique medium of Silica Biomass Cloverleaf so impressive qualities that 3 pounds of it (the amount in the Cloverleaf M25 BB filter) can contain as many beneficial bacteria and 50 filter bags diameter stone.
Moving Sand bed filters are in two different sizes and 2 versions. 1. Loose pump version (M25, M70). 2. The pump aligned (M25P, M70P). Unlike several competing products, these Moving Sand bed filters, a check valve that causes loss of sand caused by siphoning is prevented. As guidance for application and flow can be assumed that around 10% of the pond capacity by Moving Sand bed filter must be led. Due to the nature of the design and the medium, Moving Sand bed filters should only be connected to existing ponds that are not "growing pains" and more have been adequately filtered mechanically.


The M Series Moving Sand bed filters is designed for connection to a main filter pump fed. The Moving Sand bed filter is a (small) running independently powered pump. This pump is in the third or fourth chamber of the filter. The return line of the Moving Sand bed filter can lead directly into the pond. With the valve in the supply line of Moving Sand bed filter the water flow can be controlled. Flow of 10% of the water volume per hour is sufficient.
