Why Does My Pond Filter Need Rocks?

Pond filters are essential for maintaining a healthy and balanced pond ecosystem. They work by removing harmful debris, excess nutrients, and organic matter from the water, preventing algae blooms and maintaining water clarity. Rocks play a crucial role in the filtration process, acting as a vital component of many pond filter systems.

One of the primary reasons rocks are essential in pond filters is their ability to provide a large surface area for beneficial bacteria to colonize.
