Benefits of Mechanical Filtration
Mechanical filtration can greatly improve the health of most ponds, 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 debris from your pond 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.
