Waterfall filters can also be used as an overflow basin to feed into a waterfall or stream providing a very natural looking pond design when properly landscaped.

Our top pick in this category has to be the Laguna High Performance Powerflo Filter Falls. This filter uses a water spray bar to increase the oxygen content of the water before it passes through the biological filters. This greatly enhances the biological activity in the filter and increases oxygen content of the pond water. Other filters pump the water in at the bottom of the filter and the water exiting the filter is actually lower in oxygen content than it was when it entered. The Laguna filter does not require an expensive, flow restricting check valve to stop sludge from entering the pond during pump maintenance or power failures like most other waterfall filters do. The filter pads in the Laguna filter are also far easier to maintain than all other brands and offer a wider variety of filter pad densities.

A major advantage over other filters is the use of vertical filter pads. Most other filters use horizontal filters pads that stack one on top of the other, with the bio media placed on top of them. To clean the bottom pad in other filters all filter media must be removed. This is time consuming and messy. But with the Laguna model each pad can be individually removed and cleaned with no mess.
