The Tetra EasyCrystal FilterPack 250/300 with AlgoStop is a replacement filter medium for the Tetra EasyCrystal internal filter and is used for chemical, mechanical and bioactive filtering in the freshwater aquarium.

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 Filter Pack filter cartridge is a replacement filter medium for use in the Tetra EasyCrystal internal filter. The filter cartridge can be changed quickly and easily without getting your hands wet. The white filter fleece takes over the rough pre-filter function. The green filter fleece serves the narrow-pored fine filter. Thanks to the practical clip holder, the cartridge can be changed quickly and cleanly. The anti-algae active ingredient is placed in the water flow to achieve optimal distribution and active ingredient dosing. Algae are actively inhibited in their growth.

The degree of contamination of the filter can be determined with the flow rate of the water. Depending on the filter type, it is cleaned every two to three months when the flow is reduced by about half. Warm tap water or better aquarium water is used to wash out the filter material. When using filter sponges, hot or cold water should never be used for this, as this destroys useful filter bacteria. Under no circumstances should cleaning agents be used. Regularly changing the filter pack of the Tetra EasyCrystal Filter is much easier and faster.

The delivery includes 3 filter cartridges.

Oliver Knott recommends:

With the Tetra EasyCrystal Filter Pack with AlgoStop, you not only change your filter cartridges quickly and easily without getting your hands wet, but you also actively counteract the growth of algae!
