Tetra EasyCrystal Filter Range

More information

The Tetra EasyCrystal Filter range offers a simple and highly effective solution for maintaining crystal-clear water in freshwater aquariums. Designed for ease of use and consistent performance, this internal filter system is available in three sizes and suitable for aquariums from 15 to 150 litres. All models feature intensive mechanical and biological filtration to ensure optimal water quality with minimal maintenance. The mechanical stage consists of double-layered filter floss pads that reliably trap both coarse debris and the finest particles. For biological filtration, a built-in BioGrid with an extra-large surface area supports the colonisation of beneficial bacteria, helping to break down harmful substances such as ammonia and nitrite. One of the key advantages of the EasyCrystal system is the convenient, mess-free cartridge replacement, which can be completed in just seconds - without the need for rinsing or getting your hands wet. Those cartridges are available in two different versions: with activated carbon embedded to remove discolouration of the water and unpleasant odours or without additional carbon filtration - both leaving the water visibily clearer. For best results, the filter cartridge should be replaced every four weeks. The compact and space-saving design of the filter makes it ideal for modern aquarium setups. The units operate with a whisper-quiet motor that won’t disturb fish or aquarists. The EasyCrystal Filter 300 and the EasyCrystal Filterbox 600 come with an integrated heating compartment, designed for clean water and easy temperature regulation in one compact housing. TÜV/GS tested for safety and quality assurance, all EasyCrystal filters have a two-year warranty, offering peace of mind along with proven Tetra engineering. Whether for a nano tank or a community aquarium, the EasyCrystal range delivers dependable filtration and clean water, making it an ideal choice for both beginners and experienced aquarists alike.
