Freshwater - Filter materials
Cleaning the water is done using the filter. Using a pump, the water is pumped through a number of different filter materials.
This filters waste produced by fish, plant remnants and excess food from the water. In addition to this, the filter serves another important function. It is a source of useful bacteria which help to establish a good biological balance. The bacteria in the filter ‘eat' the toxic waste materials in the water. There are biological, absorbent and enriching filter materials available for the HS aqua Quadro Aquarium.
Biological filter materials
HS aqua Denilit and HS aqua Ceramic Filtermediumare biological filter materials. HS aqua Denilit has a highly porous structure and a large surface area. This provides the ideal surface for useful, waste-material reducing bacteria to attach themselves, thereby contributing to the natural processing of the waste in the aquarium. HS aqua Ceramic Filtermedium is the ideal pre-filter material. The tubular form ensures that the filter material is easy to keep clean.
Adsorbent filter materials
HS aqua Carbon Activ S, Carbon Activ L, Carbon Superactiv S, Carbon Superactiv L and Zeoliet are adsorbent filter materials. These materials are capable of adsorbing or binding harmful substances such as ammonia and medication excreted by the fish. After several weeks or months, the filter materials will be saturated and must be replaced.
HS aqua Carbon Activ S and Carbon Activ L are high-quality charcoal products. HS aqua Carbon Activ S is used for a rapid removal of waste materials and HS aqua Carbon Activ L is normally used to remove odours, colours and toxins from the water. If an extremely high absorbent capacity is desired, we recommend using HS aqua Carbon Superactiv S or HS aqua Carbon Superactiv L. HS aqua Zeoliet is a filter material that is very suitable for aquariums with a varying biological load. HS aqua Zeoliet is a natural rock that binds the harmful waste product ammonium.
Enriching filter materials
HS aqua Torogran is an enriching filter material. This material is used to create a slight acidification and brown colouration in the water, helping to create a natural environment for tropical blackwater fish.
