Filtering

In an aquarium a good filtration is essential. Aquarium fish feel more comfortable in clear and clean water. Also in clear water the light penatrates deeper to the bottom. Harmful substances are transformed by bacteria to un-harmful substances. Above all a good water circulation spreads CO2 and nutrients through the aquarium and improves the water quality.

Subcategories

  • Filters

    A filter keeps the aquarium clean and fresh and contributes to a healthy water quality. Waste materials travel through the inflow to the filtermedia and are filtered. An external filter can be placed out of the view and is easy accesseble for maintenance. This is a great advantage compared to an internal filter.

  • Inflow & Outflow

    With the right inflow and outflow a good current and water circulation can be established in the aquarium. A glass filter inflow looks stylish and is barely noticable under water. A metal inflow and outflow pipe is robust and timeless.

  • Filtermaterials

    Filter materials keep the aquarium clean, clear and fresh! Fish and plants release all kinds of harmfull substances that pollute the water. The right type of filter media is of great importance for the water quality.

  • accessories

    An aquariumfilter keeps the water clean and clear and provides a good water quality. With a good water circulation the CO2 and nutrients are spread out in the aquarium. Waste materials are sucked in by the filter inflow and are quarantined in the filtermedia to leave the filter as cleared water.
