Fluval Chi Replacement Foam / Filter Pad Combo Pack

The 2-sided polyester/carbon Filter Pads provide thorough and effective mechanical and chemical filtration and are custom-sized to fit perfectly in the filter chamber to prevent debris bypass.

The polyester side filters out debris and contaminants, while the carbon side filters out harmful liquid substances, colorants and odors.

The Foam Pad captures excess particles and debris, plus it supports the growth of nitrifying bacteria for a healthy and clean environment.
