Permanent phosphate removal 

The important plant nutrient phosphate is required only in small amounts. An over-supply creates algae problems.

sera phosvec Granulat removes phosphate easily and safely with long-term effects. The granules remain active up to three months, according to the aquarium size and the water pollution. Suitable for filtration of fresh and marine water.

Recommended dosage

Place a filter media bag with sera Phosvec Granulat into an area of the filter that is protected from dirt. The granules remain active up to three months, according to the aquarium size and the water pollution. Replace the granules if the capacity is used up (noticeable by an increased phosphate level). Before first use, briefly rinse the filter media bag (filled with Phosvec Granulat) under running water.
