Tetra Tetratec Internal Filter EasyCrystal 250

The Tetra EasyCrystal Filter 250 is used for mechanical, chemical and biological water treatment in aquariums with a volume of 15-40 litres and is intended for use in freshwater aquariums.

For the well-being of your fish and plants, permanent filtering of the aquarium water is necessary. Tetra filter technology safely breaks down excess nutrients and thus ensures permanently good water quality. The filter is the heart of every aquarium and is therefore chosen to fit every biotope. It is not only the size of the tank that is important, but also its inhabitants. At Tetra, all AquaArt complete sets contain the right filter for the fish stock suitable for the respective aquarium. However, if the circumstances change because the fish are multiplying or very small animals such as dwarf shrimp are feeding in, the existing filter may also have to be replaced by a more suitable one. Here Tetra offers a variety of devices that are suitable for all tank residents and aquarium sizes.

The Tetra EasyCrystal internal filter 250 ensures crystal-clear and healthy water thanks to its intensive mechanical, biological and chemical filtering. In mechanical filtering, a double-layer filter fleece reliably removes even the smallest floating particles. The white side is used for rough pre-filtering, the green side for fine filtering. Filter sponge and bio-balls with an extra-large surface for the settlement of useful cleaning bacteria are used for biological filtering. Special activated carbon is used to eliminate water discolouration and unpleasant smells and thus chemically clean the aquarium water. Cleaning the Tetra EasyCrystal Filter 250 is extremely easy: the filter cartridges are replaced every 4 weeks. No more washing out of the filter medium and wet hands are a thing of the past! The powerful magnetic turbine enables a high water flow, the compact housing saves space. Thanks to the flexible suction cups, the internal filter can be attached flexibly and securely. The filter media are available as spare parts. The Tetra EasyCrystal Filter 250 is TÜV / GS tested, CE certified and has a 2 year guarantee.

Tip: filter cleaning and changing always mean a loss of filter bacteria. With Tetra Bactozym, the bacterial activator, you can compensate for this loss in no time.
