AQUAEL presents a revolutionary new line of internal aquarium filters. The ASAP filters combine high performance and great usability features with a clever design that reduces time spent on maintenance. The ASAP internal filter consists of a modern energy efficient motor in a stylish housing and a large transparent filter shell filled with carefully selected filter sponge. The sponge is quickly colonized by beneficial bacteria, so that the water flowing through the filter is subjected to biological and mechanical filtration. Thanks to this, it remains clear and safe for the inhabitants of the aquarium. The filter requires two basic types of maintenance processes. One is to remove the filter tray and replace it with a new one (we offer standard cartridges as well as cartridges with activated carbon or phosphate absorber to prevent the growth of algae). The other includes rinsing the filter sponge in the water drained from the tank. This operation can be without the need to remove the entire filter from the aquarium tank, which significantly reduces maintenance time. The new ASAP internal filters are also ideal for use in aquaterrariums as they can work in shallow water up to 5 centimetres deep. In addition, they effectively stimulate water in the tank with oxygen by causing strong movement of the water surface.
