The filtermaterial is opposition to sponges, brushes, lava stones
etc., free of maintenance. Therefore the filter has to be cleaned
only in intervals of a few months. The cleaning is easy and basically
consists in opening the faucet. In the trickling the water is naturally
oxygenated and therefore there is no artificial oxygenation of the
pond with for example airbulbs necessary.
