Application:
Filter material which reduces the concentration of toxic substances in all ponds-

Zeolite is a well-known filter material and has been highly esteemed by Koi-breeders for a long time because its surface area is 1000x larger than sand or gravel. The large surface of the filter material is crucial for the settlement of the right micro-organisms. This helps to achieve naturally clear water. Pondlith by OASE is a specially processed Zeolite with a grain that was exclusively developed for use as filter material for garden ponds.

Pondlith can do a lot for a pond:

In open agricultural systems - such as an open field - the toxin ammonium is broken down by bacteria. This way poisonous concentrations are avoided. In closed systems - such as the garden pond - where no exchange of substances is possible, the concentration of ammonia can rise so high that it becomes poisonous for the occupants of the pond. The fish, decomposition of uneaten fish food and fish excrement produce so much ammonia that it cannot be broken down by the bacteria in a normal garden pond. Pondlith works in a natural way to prevent the poisoning of water by reducing the concentration of toxic substances through the bacteria living on its surface. Pondlith also works as an ion exchanger in the garden pond. The mineral  Zeolite is a natural ion exchanger. For the quality of the pond water, that means that certain organic compounds - i.e. nutrients - are being dissolved which stops the growth of green algae. This prevents the clouding of the water.

2.2 lbs. of Pondlith per cubic yard of water works in a pond without fish. In a pond with fish twice as much should be used and in a pond with Koi-fish 8.8 lbs. per cubic yard are necessary.  5.5 lbs. of Pondlith enclosed in a filter basket can be used immediately wherever pond water is moving. It can also be used to as replacement granulates in the BioClear 2 and BioClear 3 Filter Systems.
