Premium aquarium filter media for custom mechanical filtration
Cut-to-fit filter media pads accommodate most aquarium filters
Coarse media keeps aquarium water free of larger debris particles
Coarse-density filter media excellent for general-purpose mechanical filtration. Drs. Foster and Smith Coarse (Black) Pads keep aquarium water clear of larger particles and help protect biological filter media from clogs and debris buildup that can affect overall aquarium water quality and health.
Benefits of Mechanical Filtration
Mechanical filtration can greatly improve the health of most aquariums, and is also important for efficient biological filtration. The process is simple: mechanical filter media strains solid debris such as fish excrement, sludge, uneaten food, or dust from your aquarium as water passes through.
The debris-laden mechanical filter media can then be easily removed and rinsed or replaced. Mechanical filter media not only reduces the amount of solids in your water, but more importantly, it keeps debris from reaching your biological media, building up, and creating dead spots where nitrifying bacteria can't reproduce.

Biological filtration is the action of bacteria breaking down dangerous ammonia, converting it to nitrite, and then converting nitrite to less toxic nitrate. This article discusses how the process works.
