The ASAP filter combines high performance and excellent usability with a well thought-out design that reduces the time needed for maintenance work. The AQUAEL ASAP Internal Filter consists of a modern, energy-efficient motor housed in an elegant casing and a large transparent filter bowl filled with a carefully selected filter sponge. The sponge is quickly colonised by beneficial bacteria, so that the water passing through the filter is subjected to both biological and mechanical filtration. Filter sponges with activated carbon and phosphate absorber are available as accessories. The AQUAEL ASAP Internal Filter is also ideal for use in aquaterrariums, as it can work in shallow water with a depth of 5 cm or more. In addition, the water is enriched with oxygen by moving the water surface strongly.
