Fluval Chi Filter Pad 4 Pack - Premium Foam Replacement Pads for Aquarium Filters - Perfect for Fish Tank Maintenance and Water Clarity

Perfect Filter kit for my Fluval Chi Aquarium. Has 3 filters and 1 foam pad a good kit to last about 4 months. Rinse your filter weekly in the aquarium water. Replace filter every 2-4 weeks. The foam pad should be replaced every 2-3 months. This is according to the directions. My experiences with the foam is that I can get 3-4 months out of it.
