How do I carry out a water analysis of my pond or basin?

Who hasn't dreamed of seeing their fish evolve in clear water, surrounded by lush plants? Everything starts in a pond with optimal water quality. Well-balanced water will allow you to have vigorous plants and healthy fish!

How do you know if your pond water is in optimal condition? How do you analyze your pond water to ensure its quality throughout the year? Many of us ask ourselves these questions regularly. In this article, we will try to gather the answers to these questions.

We will see, among other things:

  • Why water analysis is a crucial element for the aquatic ecosystem,
  • What key parameters should be monitored?
  • How to react based on the results obtained

I. The seasons and their impact on the basin ecosystem

The seasons are like the conductors of your pond, dictating the rhythm of aquatic life throughout the year. Each season therefore brings its share of changes and demands on your aquatic ecosystem. Understanding this impact is essential to maintaining a healthy and balanced pond.

1. Spring - The Awakening of Nature

Spring, a symbol of renewal, sees your pond emerge from its winter lethargy. Temperatures rise, plants begin to grow, and fish become more active. However, this season also brings challenges. Spring rains can introduce unwanted elements into your pond, such as contaminants and debris. Water testing becomes crucial to monitor these changes.

Tips for spring

  • Regularly clean leaves and debris that have fallen into the pond.
  • Check filters and pumps for better water circulation.
  • Monitor water temperature carefully to adjust fish food accordingly.

2. Summer - The zenith of the ecosystem

In the summer, your pond is at its peak. Fish are swimming vigorously, plants are lush, and aquatic life is at its peak. However, high temperatures can cause fluctuations in pH, affecting the health of your fish and plants. That's why regular testing is necessary to adjust water parameters accordingly.

Tips for summer

  • Avoid overfeeding fish, as higher temperatures reduce their appetite.
  • Check water pH and hardness frequently, especially during heat waves.
  • Make sure that aquatic plants do not invade the water surface too much for adequate oxygenation.

3. Autumn - Preparing for winter

As fall approaches, your pond is preparing for winter. Leaves fall, temperatures drop, and aquatic life becomes less active. Organic debris accumulated in your pond can cause changes in water quality. This is a great time to conduct a water test and prepare your aquatic ecosystem for the colder months.

Tips for Fall

  • Install a protective net to prevent leaves from entering the pond.
  • Gradually reduce the amount of fish food in preparation for winter.
  • Clean pumps and filters to prevent clogs during the cold season.

4. Winter - The rest period

Winter slows everything down, including your pond. Fish become lethargic, plants hibernate, and water cools. While less maintenance is required in winter, it’s still important to monitor water quality. Extreme temperature swings can disrupt the chemical balance of your pond.

Tips for winter

  • Install an aerator to maintain good oxygenation under the ice.
  • Avoid walking on the ice to avoid disturbing hibernating fish.
  • Reduce food rations as water temperature drops.

In short, each season brings its own set of challenges for your pond water quality. Regular testing allows you to understand these seasonal variations and adjust water parameters accordingly. By staying attentive to the needs of your aquatic ecosystem throughout the year, you can ensure a healthy and thriving pond, no matter what season is on the horizon.

II. Key water parameters to be analyzed in all seasons

To care for your pond or pool in any season, it is essential to understand the water parameters that you need to monitor closely. These parameters serve as a compass for maintaining a balanced aquatic ecosystem. Discover below the essential parameters and specific tests for each season.

1. Monitoring pH (Hydrogen Potential)

pH, short for Potential Hydrogen, is a crucial indicator of the health of the water in your pond. It measures whether the water is acidic, neutral, or basic. For most fish and freshwater plants, a pH between 7 and 8 is ideal. Make sure the pH does not exceed 8 to avoid the formation of toxic compounds.

Tips for pH:

  • Use specific pH test kits for accurate measurements.
  • Adjust pH according to seasonal needs to maintain optimal balance.

    If you notice high levels of ammonia (NH3) or nitrites (NO2) in your pond, it is essential to take steps to restore a healthy environment for your fish and aquatic plants. Here is what you can do:

    1. Seeding your filtration system with bacteria
      One of the common causes of high ammonia and nitrite levels is an imbalance in your pond's nitrogen cycle. Nitrifying bacteria are responsible for converting ammonia to nitrite and then to less toxic nitrate.
      If these bacteria are not present in sufficient quantities, you can seed your filtration system with special nitrifying bacteria cultures. Be sure to follow the product instructions for effective use.
    2. Reduce the amount of food distributed
      Overfeeding your fish can contribute to ammonia buildup. Make sure you feed your fish a balanced diet and avoid excess.
    3. Avoid using zeolite if your water contains salt.
      Zeolite is sometimes used to absorb ammonia, but it may not be compatible with salt water. Be sure to check the compatibility of zeolite with your water chemistry before using it.
    4. Perform partial water changes
      If ammonia or nitrite levels remain high despite your efforts, consider performing partial water changes to dilute these toxic substances. Use unsoftened spring or tap water to fill your pond.
    5. Monitor water parameters carefully
      Continue to perform regular water testing to ensure that ammonia and nitrite levels are decreasing and remaining at safe levels for your fish. Adjust your actions accordingly.

    If despite these measures, ammonia or nitrite levels persist at dangerous levels, it may be helpful to consult an aquaculture or pond professional. They can provide you with advice specific to your situation and help you resolve the problem effectively. Quality water is essential for the health and well-being of your fish and aquatic ecosystem.
