ASAP filter: It provides effective mechanical and biological filtration, as well as aeration of water. This filter is as easy to use as possible. It has a transparent container for filter media, which allows easy monitoring of the level of contamination of the cartridge, without having to disassemble the entire device.Both the installation and operation of the filter are intuitive and certainly can handle them, even a novice aquarist. The device is mounted on the aquarium glass with four strong suction cups. To clean the sponge, it is enough to disconnect the cartridge container, remove the sponge and rinse it in the water poured from the aquarium. Therefore, there is no need to remove the entire filter from the tank, which significantly reduces the service time and is a convenience for the user. The ASAP filter also allows you to change the direction of the water jet very easily (within 90°). All you have to do is turn the filter container in any direction.Heater FIX: Electronic, glass aquarium heater with a built-in microprocessor thanks to which the device automatically adjusts the heating power to maintain the right water temperature and prevent its rapid fluctuations.
