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 media traps solid debris such as fish excrement, sludge, uneaten food, or dust from your aquarium as water passes through. Debris-laden media can then be mechanically removed and rinsed or replaced with ease. This not only reduces the amount of solid debris in your water but prevents debris from rapidly clogging biological media and creating conditions that prevent efficient breakdown of waste.
