The pre-filter provides you with an additional tool to keep your pond clean. The pre-filter ensures that larger pollutants in the pond water, such as leaves, small branches, and larger algae particles are collected before they are caught up in the pump or the filter.
Benefits:
* Prevention that larger particles will clog up or overload the filter
* Protects the lifespan of the pond pump
* Transparent housing: easy to see when it requires cleaning
