Starting up your pond in the spring

In the spring, your pond comes back to life. Plants start to grow and fish awaken from their winter rest. Time to get your pond started! In this blog, we’ll tell you all about the necessary pond maintenance in the spring.

Clean your pond

After the winter, it is important to clean your pond. Remove silt, loose leaves and dead aquatic plants from your pond and check the roots of the remaining plants for signs of rot. Cut these away as necessary. It is best to do this after the night frost has completely disappeared. This will prevent the plants from dying and rotting after all.

Check the pond technology

When your pond comes back to life in the spring, it is essential that the pond technology works optimally.

  • In winter, parts can freeze to pieces. Therefore, check all connections, pipes, hoses and equipment for leaks and damage. Make sure everything is in order and properly cleaned.
  • Now that the temperature is rising and the fish are eating and relieving themselves again, a properly functioning pond filter is very important. Does the water temperature rise above 7 degrees? Then the filter and pump can be placed back in the right location and turned on to purify the pond water.
  • A UV-C device is indispensable in your koi pond or swimming pond. It is the solution to algae and green water. Replace your UV-C lamp every spring for the best results.

Restore the biological balance

Starting up a pond is important to restore the biological balance in the water. If the filter pump is turned off during the winter, most of the bacteria in your pond and filter die off. This includes the beneficial bacteria that take care of the breakdown of harmful substances, such as feces from pond fish or leaf litter from pond plants. By restarting your pond in the spring, you promote the recovery of the bacterial culture. It takes several weeks for sufficient microorganisms to develop and a biological balance to be achieved. To speed up that natural process, you can add good pond bacteria to your pond.

Measure the water quality

To enjoy your pond optimally it is important that your pond water is in top condition. Therefore, check your water values regularly. Even if you start up your pond in the spring. The most important water values in your pond are: acidity (pH), carbonate hardness (KH), total or joint hardness (GH), ammonium, nitrite and nitrate. You measure the water values by means of test strips, drop tests or electronic measuring devices. To achieve and maintain the ideal water quality in your pond you can add water treatment and water improvement agents. So you are assured of a (swimming or koi) pond in top condition!
