Monthly service kits for the Interpet PF4 range of filters. Each 3 pack contains 3 x monthly service kits (3 months supply) and each 6 pack contains 6 months supply.

Filter floss will become blocked with trapped material and the carbon capacity for removing toxins will become exhausted. The carbon foam filters are ideal for chemical filtration in the aquarium, and will remove dissolved organic contaminants from the water.

Replace every month to keep your aquarium healthy, clean and clear.
