The PSM system can produce crystal clear water that allows the choice of either a bare liner or a gravel and decorative rock liner cover without concern for the accumulation of debris.

PondSweep Skimmer

Purifalls© Biological Filter and Waterfalls

The PSM family of filters will purify up to 20,000 gallons of water when used together as part of the PSM Ecosystem, or even larger ponds with multiple filters.

1. The new cross-flow design of our skimmer assures that even the largest pumps (20,000 gph in the PS1500) will be protected by a leaf net and uncut filter mats.

2. Surface water is drawn into the bellows weir opening. Our patented bellows-weir design dramatically increases pond skimming and also simplifies skimmer and pump maintenance.

3. Our constant-flow design forces more water through the mats even when dirt partially blocks the flow of water through the skimmer. One glance will tell you when the mats should be cleaned out.

4. Bulkhead Fitting (sandwiching liner): The bottom drain inlet goes through the liner near the surface and next to the skimmer, not through the pond bottom.

5. Auto fill Valve (optional): Maintains water level without the need to monitor. Less water is added at one time, preventing problems caused by adding cold water and over chlorinating.

6. External or submersible, standard or high-efficiency pumps are hidden outside the pond and operate silently for years to keep your pond water crystal-clear. (Purchase separately)

7. Bottom Drain. (optional). Recommended for heavy fish loads and ponds over 2' deep.

8. We recommend 45 mil, fish-safe PondGuard© (from Firestone) liners with or without underlayment depending on soil conditions. (Purchase separately)

9. Rocks and gravel in the stream and pond can be used to hide and protect the liner, and add a huge biological substrate for pond bacteria and natural aquatic landscaping without the need for pots.

10. Underwater lights low Voltage or Fiber Optic make your pond sparkle at night. (optional).

11. Ultraviolet Light Sterilizer (optional).

12. A built-in waterfall ledge holds the waterfalls stone. Water flows downstream from the biological filter into the pond aerating the water as it cascades.

13. Flexible piping simplifies installation to save time.

14. Flexible piping if freezing risk and tree roots; rigid piping for warm climates

15. Optional gravel/rock plant mesh baskets or adjustable rock shelf hide the filter edges and create plant filter pockets. Typically requires only annual cleaning.
