Why Water Temperature Matters When Caring For Your Pond

water temperature

The water temperature in your pond fluctuates throughout the year and you need to understand how it affects your pond habitat. It can determine the health of the fish and the plants in your pond.

Pond Temperature Basics

In the summertime, when the top layers of your pond water are warm and the lower layers are cool, a pond can lose the oxygen it needs to keep fish alive. Warmer water holds less oxygen leading to dead fish and lower decomposition of the pond bottom. Algae growth can increase and aquatic weed control is essential to prevent invasive water plants from thriving. Low water temperatures in the winter can cause water flow problems and toxic gas buildup because of freezing.

Summertime Care

Your pond in the summer needs ample aeration to supply the necessary oxygen for your fish and plants to thrive. Combined with regular maintenance and cleanup of debris that blows into your pond, you’ll have a wonderful, clean area for swimming, boating and fishing. Top-down aeration can happen with the use of a fountain. This is a quick and easy way to provide additional aeration on the surface, which is the area lacking oxygen when it’s warm. Bottom-up aeration can provide a more thorough supply of oxygen throughout all the layers of your pond water and can naturally absorb excess nutrients in the water.

Wintertime Care

As the water temperature drops and possibly ices over, the warmer water stays below the surface. This warm layer allows fish and plants to survive the winter months, but toxic gas can buildup if there’s no release system. A deicer can be used to promote gas exchange in the cold weather.

Depth can make a large difference to the water temperature in your pond so make sure you take temperatures throughout the year so you know the specific needs of your unique pond environment.…
