Oase Aquarium Internal Filters

OASE offers clever internal and external filters that ensure the balance in the sensitive miniature eco-system. All OASE filters follow mechanical-biological principles. Mechanically the filter first removes suspended substances and remains of fish food, plant parts or excrement. The term biological filtration is used when bacteria and microorganisms settled in the filter take over the rest of the filtration task: Bacteria and micro-organisms that have settled in the filter, feed on organic substances, transform these organic substances or completely remove them from the cycle.

 

An internal filter is placed inside of the tank and is particularly suited for more compact aquariums to 200 litres. It has also proved to be effective as a breeding tank, quarantine tank or shrimp tank. With internal filter cleaning likewise occurs in different stages in a combination of mechanical and biological processes.
