Garden ponds require filters in order to maintain the quality of the water. It is possible to create your own filter using some common materials that you can purchase at a hardware store. This project should only a few hours to complete.

Step 1 – Safety

Be careful when using power tools. The power switch to the drill should be turned to the off position before the drill is plugged into an electrical outlet. The drill should also be stored in a safe place when you are finished using it.

Step 2 – Building the Garden Pond Filter Container

Use the plastic bucket as the reservoir for the pond water. Use your utility knife to cut a hold in the lid of the bucket. Use your drill to create a hole in the lower part of the bucket. The hole will need to be the same size as the PVC pipe. This spot is where the water will pulled through the filtration system and back into the pond.

Step 3 – Installing the Filter Pipes

Position a piece of your PVC pipe into the hole you made in the bucket. The pipe will need to stretch between the bucket and pump. Use the silicone sealant to secure the pipe to the bucket. Read the instructions provided by the manufacturer of the sealant before you use it. Carefully apply the sealant around the hole once the pipe has been place in it. Allow the sealant enough time to cure completely. Insert a length of flexible tubing into the PVC pipe. This tubing will connect the filter to the pump.

Step 4 – Installing the Filtration Parts in the Filter

In order to keep you pond water clean, you will need a proper filtration mechanism. This mechanism will include a mechanical and biological filter. Use small rocks for your biological filter. Place the rocks inside the bucket. The rocks will provide a habitat for bacteria and a weight to hold the mechanical filter in place. The mechanical filter should be made with pond filter fabric. The fabric can be purchased at your local hardware store or gardening shop. This material allows the water to flow through while trapping any debris and particles that would contaminate the pond. Place the fabric over the rocks. Top the fabric with a small piece of screen. The screen will prevent larger particles from clogging the system. Once all of the filter parts have been placed in the bucket, secure the lid to the top of the container.

Step 5 – Setting Up the Filter

Bend the plastic tubing in order for it to connect to the intake hole of your filter. Immerse your filter into your pond. Wait until all the of the air bubbles have stopped coming out of the filter and the container has sunk to the bottom. Turn on your pump.
