Interpet Polymer Wool 40g

Description

Particles of food, decayed organic material and inorganic ‘mulm’ cause water clarity problems, harbour disease and spoil the appearance of the aquarium. Large particles should be removed by coarse filter media such as Interpet Bio-Media to prevent them blocking the filter prematurely. Fine particles which pass through coarse media will still spoil the water clarity, so the water should then be passed through Polymer Filter Wool. 40g
