POND VOLUME
It is important to calculate the estimated water volume before you begin construction, and then re-calculate final water volume when your project is completed. Estimating water volume pre-construction is a step that is often skipped by many homeowners and contractors. A water garden with undersized filtration can prove to be a maintenance nightmare.

Use the product specification/cross reference guide on page 2 to verify the maximum pond volume and flow rates for Pro Series Equipment.
TO DETERMINE POND VOLUME
Multiply (in feet) the average length x the average width x the average depth to find cubic feet of pond volume. Multiply cubic feet x 7.48 = gallons
SURFACE AREA
When using any pond skimmer it is important to keep the surface area (in square feet) of the pond in mind. Upon start-up, the pump sends water from the bottom reservoir to the top of the waterfall and/or streambed. The water must then fill, from top to bottom, the waterfalls and streambed until it eventually re-enters the pond and the water levels equalize. During the water in transition process, the water level of the bottom reservoir is continually dropping. If the streambed is built improperly, or is built too big, the water level of the bottom reservoir could drop below the opening in the skimmer before the water levels equalize. This would result in the pump running dry and starving for water. This situation can be easily avoided by using the formula provided to calculate the surface area of your pond. With that number, you can then determine the maximum surface area of waterfalls and streambed that your pond can accomodate.
TO DETERMINE SURFACE FOOTAGE
Multiply (in feet) the average length x the average width = total square feet of the pond surface area. Multiply the surface area of the pond x .5 = maximum surface area for falls

PLACEMENT OF THE FILTERFALLS AND SKIMMER
Now that you have determined the size of the pond, waterfalls and filter system, it is time to determine the placement of the components. Whenever possible, it is best to position the Skimmer and FilterFalls directly across from each other at opposite ends of the pond. This setup creates a current that pulls surface debris into the Skimmer. If the Skimmer and FilterFalls are placed too close together, or the pond has an unusual shape, dead areas can occur. These dead areas can be eliminated with the use of multiple falls or multiple skimmers.
STREAMBED CONSTRUCTION
Using proper streambed construction techniques can limit the transitional water needed to fill the streambed and enables the system to function optimally. Transitional water is determined by the height that the weir rock extends above the liner at the spillway opening. Maintaining the shortest distance possible between the top of the weir rock and the liner is a crucial component to a properly functioning water garden. Figure 3 displays two examples of proper construction techniques for minimal transitional water.
Figure 4 is an example of improper streambed construction. Stone, gravel and foam can be combined to make a barrier and create a waterfall, but that barrier will never be watertight. When the pump is turned off, the water will always drain down to the highest point of the liner. Improper construction greatly increases the water in transition.

Pro Series Skimmer Installation
EXCAVATING AND SETTING THE SKIMMER
Prior to setting the skimmer you must first determine the surface level of the water in the pond. Once you have this number you can excavate for the Skimmer. The excavation should be a few inches wider and longer than the Skimmer body. Find your model number below to determine the approximate depth of the hole. Do not dig too deep. The skimmer should be set on undisturbed earth if possible. In the case that you over-dig, be sure to compact the soil thoroughly to prevent settling. The bottom of the hole should be level side-to-side and front-to-back.

Place the Skimmer enclosure into the excavated hole. Check the top of the enclosure to make sure that it is level front-to-back and side-to-side. Check where your pre-determined water level falls on the face of the Skimmer enclosure. The water level needs to be between 1¼” and 1 ½” below the top of the weir door opening and even with the water level indicator molded on the side of the Skimmer. (PS15000 only) Make sure that any unexcavated soil that is left in front of the Skimmer is at least 10” below water level (See Figure 5). This will ensure that there is enough room for the weir door to be installed and function properly. Before you go any further into the Skimmer installation, place a few stones inside the Skimmer enclosure to weigh it down and keep it from moving. Install the solid support bar(s) and begin backfilling. The support bar(s) must be in place for the enclosure to retain its shape during the backfilling process. Loosely backfill the enclosure on all sides, lightly compacting as you go. Do not over-compact the soil. Aggressive compaction may deform the enclosure and cause components to fit improperly.
ATTACHING THE LINER
Hold the liner up against the face of the Skimmer, allowing a minimum of 2” to extend above the top of the enclosure. Leave some slack in the liner below the weir opening. This will help avoid any future strain on the liner connection.
Make sure that the front surface of the Skimmer and the back side of the liner are clean and free of debris.
