The pre-filter makes sure that bigger waste items in the pond water, like leaves, tiny branches, and bigger algae particles, are captured before they become caught in the filter or the pump.
You can avoid the filter becoming clogged or overloaded by pre-filtering the water to remove bigger particles.
