Askoll Pure Zeolite, a filtering material to reduce ammonia and phosphate values
Zeolite Askoll is a natural mineral in granules with a high ion exchange capacity, able to retain the ammonia and phosphates present in the aquarium water.
Its periodic use allows you to monitor the value of ammonia, counteracting the growth of many algal forms: it helps to eliminate dyes and increases the clarity and transparency of the water. It does not release heavy metals and other harmful substances.
The package includes a sock for inserting the material inside the filter.
