The Velda Internal Venturi Filter is a trouble free filter system for your pond. It filters and aerates your pond water at the same time. With the help of the snorkel, the built in pond pump sucks in a constant supply of oxygen to feed the friendly bacteria that clean the pond.
The Venturi comes equipped with all of the necessary filter materials, and the built in pump, aeration hose and snorkel can all be simply connected.
The Venturi filter cleans the pond in 2 biological stages:
In the first stage, the visible dirt particles are removed by the filter foam.
In the second stage, the growth of micro-organisms is stimulated with the help of the ‘Filtra-Sub’. These micro-organisms remove organic elements from the pond water.
In both stages, the activity of the filter material is optimum due to the constant oxygen supply, resulting in clear and healthy pond water.
