The smallest in AquaEl\'s innovative range of internal filters, theASAP 300 is designed to make sure your aquarium stays beautiful at all times. Suitable for aquariums up to 100 litres, this filter has a simple design and is easy to maintain. AQUAEL presents arevolutionary new line of internal aquarium filters.The ASAP filters combine high performance and great usability features with aclever design that reduces the time required for maintenance works. The ASAP internal filter consists of amodern energy-efficient motor placed in astylish housing and alarge transparent filter bowl filled with carefully chosen filtration sponge.The sponge is quickly populated by beneficial bacteria, so water passing through the filter undergoes biological as well as mechanical filtration. Thanks to that, it stays clear and safe for the inhabitants of the aquarium. The filter requires two basic types of maintenance procedures. One consists in removing the filter bowl and replacing it with anew one (we offer standard cartridges as well as cartridges with activated carbon or phosphate absorber to prevent the growth of algae). The other involves the rinsing of filtration sponge in water drained from the tank. This operation can be performed without the need to remove the entire filter from the aquarium tank, which is very convenient and significantly reduces maintenance time. The new ASAP internal filters are also ideally suited for use in aquaterrariums, since they can operate in shallow water as little as 5 centimetres deep.In addition, they effectively oxygenate water in the tank by causing astrong movement of the water surface. There are three models of the filter available, with acapacity of 300, 500, and 700 l/h correspondingly. They are designed for use in aquarium tanks with capacities ranging from afew dozen to 250 litres. Thanks to their functional properties, these filters can be used by beginning and experienced aquarists alike.
