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.
While most aquarists agree biological filtration is imperative for your aquarium's health, not all agree that mechanical and chemical filtration is absolutely necessary.
