Summarized by Shop
Sera Filter Wool is a fine filter media which can be used either for mechanical filtration or for 'polishing' the water to improve water clarity. Suitable for use in most freshwater and marine aquarium filters, it will trap fish waste, decaying food and other tiny particles which can pollute the water. Can easily be rinsed and re-used.
