AQUAEL ASAP 300 Aquarium Filter Sponge 2 Units

The ASAP line of innovative internal filters is notable for its simple design. You will have no trouble at all replacing the sponge cartridge or cleaning the filter. To make sure that your aquarium stays beautiful at all times, use separately available filter cartridges with activated carbon or phosphate absorbent. Since the filters can work in shallow water (5 cm deep or more), they are ideal also for aqua-terrariums.
