Site selection for filter placement

The site that you select for placing the filter should be within twenty feet of the pond edge and flat. If the ground is not flat you can add dirt or gravel to level the site. As the water leaves the filter it needs to return back to the pond. The spillway liner piece is 20ft. long and 24 inches wide, so check for any obstructions that may interfere with the water returning.

The filter can be placed in full sun or partial shade but not full shade.

Avoid placing the filter in a location that may get flooded to prevent damage and the need to start all over again.

 

Site preparation

A perfectly flat site is ideal because the water depth inside the filter will be the same from side to side. Use a laser level to check for flatness or use a straight board 10 ft. long and place a level on top of it. Check for ground flatness in two directions across a 10 ft. diameter. If it is necessary to use stone fill material to level the site be sure to avoid material that may puncture the liner.

Plastic Frame set-up

The plastic frame is 6 inches in diameter and 27 feet in length. Place the frame on the flat site and form it into a circle. Using a tape measure and pencil place a mark on top of the frame 12 inches in from each open end. Then measure and mark every 24 inches along the circumference. The last mark may not measure 24 inches.

DSC_0162 (2)  DSC_0146 (2)

 

Using the drill bit provided and an electric drill make a hole at each mark for the metal stakes. Do not pound in the stakes yet.

Attach the spillway part to the open ends of the frame by pushing the open ends of the frame into the black plastic end caps. Next place one stainless steel clamps around each end cap and tighten the stainless steels clamp using a screwdriver. Make sure this assembly will not come apart by carefully tugging on it. It is possible to pull it apart if you exert too much force. The metal stakes placed 12 inches from the end caps will help hold the spillway in place.

Between the ground and the plastic frame position one piece of black geotextile material which measures 10 ft. x 10 ft.

Hammer (safety glasses and gloves should be used) the metal stakes through the drilled holes and into the ground until they are flush with the top of the plastic frame. It may be a good ideal to make sure no electric wires or pipes are beneath the filter site before you pound in the stakes.

Liner and Geotextile placement

After the frame is secured in position you can now place the filter liner material (10ft x 10ft) in place and then place the 12ft x 12ft piece of black geotextile material on top of the liner. We call this a liner sandwich because there is a piece of geotextile under and on top of the liner to provide extra protection from puncture (Picture A). The top piece of geotextile material gets tucked under the plastic frame from the outside and can be held in place with the ground staples or facia material of your choice. Be sure the liner material does not allow water to escape from a low spot before you secure the geotextile.

The remaining sections of liner and geotextile are used to return the water from the spillway back to the pond (Picture B).

Start by determining a straight path from the spillway to the pond. Using a shovel or digging tool create a shallow trench (3-4inches deep x 12 inches wide) that goes from the spillway to the pond edge. If digging this trench is not possible, pieces of lumber can be used to create a frame for guiding the water to the pond.

Place the geotextile material down first and the liner piece on top. Be sure to tuck both of these pieces under the spillway to prevent water from going where you don’t want it to. Placing a few rocks under the spillway to hold the liner in place is helpful. At the pond edge hold the liner down with a couple of rocks to keep it from floating. The extra liner material can be tucked under or hidden with stone work to create the look of a small stream.

Filter media purchase and installation

Included in the box is a Lowe’s store gift card for the purchase of two bags of gravel which serves as the filter media.

Description:

Weight per bag:

SKU number:

A small sample of gravel is provided in a sealed plastic bag for comparison. If you already have this type, enjoy the gift card.

 

Place the gravel on top of the geotextile material inside of the plastic frame. Level it with your feet or a tool that does not have sharp points or edges. The depth of gravel should be about 2.5cm or about an inch.

Submersible pump set-up and operation

Included in your package is a 120 volt submersible pump, 20ft. of black vinyl hose, pump cage and a mason brick. Connect the hose to the outflow fitting on the pump and tighten the stainless steel clamp. Place the pump inside the cage and tighten the draw strings to prevent objects from entering the cage at the top.

DSC_0211 (2)  DSC_0456

Place the pump/cage in the pond at a depth where it is full submerged. It may be helpful to tie a rope to the cage in case you need to remove the pump/cage from the pond.

Attach the end of the black vinyl hose to the mason brick using the cable tie and place this inside the filter on top of the gravel media.

Before you connect the pump to an electrical source:                                 Pump protector

Read the direction that are provided with the pump

Make sure the outlet is a GFI (ground fault interrupt) circuit

If you have any concerns about the electrical circuit, contact an electrician and have it checked.

After the pump is working, water should start to fill the filter and flow out the spillway. It may be necessary to shape the liner material at the spillway to direct the flow of water. Check the water flowing back to the pond for leaks and adjust the stream liner if needed.

The black vinyl hose that goes from the pump to the filter can be hidden beneath the stream liner or buried in the soil.

After you have run the filter system and checked for water leaks, shut it down and observe the depth of water remaining in the filter. It should be approximately three inches deep or equal to the height of the mason brick. If the brick is positioned to low it is possible to back siphon water out of the filter.

Leaf Netting

In your package is a section of leaf netting which can be used to keep leaves from accumulating in the filter. Stretch the netting over the top of the filter and secure it to the ground with the six inch metal staples.

Filter Operation

This filter is a recirculation system that is dependent on the movement of pond water to the filter where is comes in contact with natural organisms which feed on the available nutrients. From the research conducted we have found that no two pond are the same in ecology and in remediation.

Therefore it is suggested to consider the following practices:

  • Bench mark the pond water chemistry when you start the filter to establish a baseline for nutrient concentration and water condition. Do this each month and record the data.
  • Check the water flow into the filter to determine if the pump needs to be removed from the pond and cleaned. Disconnect the power before you clean the pump.
  • Check spill way for obstruction that may cause filter over flow.
  • Remove leaves and grass clippings that may fall into the filter.
  • For the first year it may be necessary to add 10-12 ounces of Filter Boost solution each month to the filter to maintain the biofilm. To do this, turn the filter off, add the solution and wait two day before plugging the filter back in. Pond water testing will indicate if this needs to be done.
  • When the pond water temperature is above 50d F. add one scoop of powder bacteria on a monthly basis to reduce the accumulation of organic sediments in the filter media. This condition may cause the gravel media may turn black and reduce the efficiency of the filter.

Water Testing

 The package contains two wide range water test kits for monitoring the water chemistry in your pond. Performing twice a month testing will provide data for decision making. Read and follow the directions on package for each test kit.
