Description Usage: Use to improve water clarity. Use to remove unwanted chemicals and medication residues after treating the aquarium. To determine the amount of activated carbon required, use at least 1g of carbon per litre of aquarium water. Rinse before use to remove any dust. Insert into a filter media bag then place evenly coverage across the filter surface to prevent water by-passing the carbon. Can be used in most types of filter, including internal power, external canister, and sump types. Available in 225g, 500g, and 1.5kg tubs and 20kg bulk bags. Other sizes are supplied in singles.
