How to Clean a Small Outdoor Pond

Keeping an outdoor pond clean and the water clear might be easier than you think. And you don't have to keep emptying it to clean it on a regular basis. Deep clean it once or twice a year, but as long as you don't keep fish in your pond, you just need to follow a simple routine maintenance method each week or two, and it will stay in sparkling clear condition. To accomplish this, purchase an inexpensive pond vacuum that works off your garden home.

Once or Twice a Month

Proper maintenance will keep your pond water sparkling clean.

Step 1

Turn off the electricity to your pond.

Step 2

Remove the pond pump and filter box. Open up the box and remove any debris that accumulated in the box. Some small pumps have the filter directly connected to the pump without a box. If this is the case, just remove the whole setup. Hose the pump and box down with water to remove any scum that may be on either. Clean the hose that attaches to the pump also.

Step 3

Remove any leaves that have accumulated on the surface of the pond. Once leaves make it into the water, they will deteriorate and become pond scum.

Step 4

Attach the pond vacuum to a water hose. Place the vacuum on the floor of the pond and turn on the water. Keep in mind with this type of vacuum, the pond is filling as it is cleaning, so be careful not to overfill the pond.

Step 5

Run the pond vacuum over the floor of the pond to pick up heavier debris that has settled to the bottom.

Step 6

To pick up floating debris, turn the vacuum upside down but keep the vacuum head just below the surface of the water so it doesn't suck in air.

Step 7

Add water clarifier and algae control, following the instructions on the packages.

Once or Twice a Year

Step 1

Turn off the electricity to the pond.

Step 2

Remove all rocks, pump and filter box, plants and anything else in the pond.

Step 3

Drain the pond of water. If the pond is small enough, you can use a bucket to dip the water out. Otherwise, you will need a pump and hose attachment.

Step 4

Wipe down the sides of the empty pond and clean up any muck left standing in the bottom.

Step 5

If you have a waterfall, be sure to clean algae off the rocks where the water flows so this algae doesn't flow right back into the pond.

Step 6

Clean the pond pump and filter box thoroughly, and replace the rocks and plants.

Step 7

Fill the pond with fresh water.
