How to Keep Garden Ponds Clear

Overview

Keeping your garden pond clear during the summer months requires daily attention. Using a proper filtration system will help, as will regular cleaning and maintaining certain chemicals. It is much easier to keep a clean pond clean than to try to fix a pond that has gotten cloudy and overgrown with algae. Having a clean, balanced pond will produce healthy, beautiful fish.

Step 1

Purchase a pond pump that will filter 50 to 200 gallons per hour per 100 gallons. If you have a large pond you will need to purchase more than one pump. You can also use an air stone to help circulate the water.

Step 2

Place your pond somewhere that the water level can be above ground level. This way your pond will not get any run off of grass and dirt when it rains.

Step 3

Use floating pond plants to cover one half of the surface of your pond. This will cut down on some of the sunlight your pond will receive, thus eliminating some of the growth of algae.

Step 4

Drain approximately 10 to 20 percent of the water from your pond and refill once per month in the summer months. In a new pond or a larger pond you may need to do this a little more frequently.

Step 5

Check the pH level of your pool using testing strips once per week. If it falls below 7.0 algae will grow and your water will turn a greenish color. You can raise the pH level using a commercial product found at your local hardware store. Follow the manufacturer's recommendations.

Step 6

Use a pool vacuum system to remove any dirt, leaves or algae from the bottom of the pond. You can use a surface skimmer to remove any leaves or grass floating on the surface of the water.

Step 7

Know how many fish your pond can hold. A general rule of thumb is for every 25 square feet of surface area your pond can hold 1 linear foot of fish.
