Measuring pH in a pond

If you have a pond, measuring and monitoring the pH of the pond is very important. Fish, plants, but also amphibians and birds live in and around a pond. Measuring pH in pond water is often done to monitor if the micro life in the pond is doing its job properly. Rain, soil and organism can change the pH of the pond water. Do you have a koi pond? Then test the pH value of the pond water regularly. 

Nieuwkoop has developed several pH meters for measuring pH in pond water that are easy to use and accurate in results. The best pH hand meter for measuring pH in ponds is the PH1200 – pH meter in carrying case.

Why is it necessary to measure the pH level in a pond?

For a pond, the pH value is very important. The plants and animals that live in it benefit most from an optimal environment and this includes a good pH value. The exact value depends on the specific needs of the organisms in the water. The balance of the water is determined by the bacteria and the oxygen plants which, through co2, change the acidity and thus the pH value of the water. During the night the pH value decreases because plants do not absorb co2 and the acidity increases and during the day the plants absorb co2 and the pH value increases again.

With a measuring device from Nieuwkoop you can make a reliable measurement and obtain reliable data on which you can monitor the pH value of the pond. It is not possible to control the pH value of the pond with additives, but it is possible to add plants or install a biological filter. It is important that when you have a koi pond that you often test the values in the water.

How can you test the pH level in a pond?

When you have a pond you can test/measure the pH level in the pond in different ways. The most simple way is to use pH test strips. You hang these briefly in the water in the pond or in the sample that was taken from the pond. Then the pH test strip discolors based on the pH value of the water. However, this remains an indication and will never give the exact pH value.

If you want to measure more accurately and thus more reliably use a digital pH meter. A digital pH meter, depending on the model, measures the pH value of the water in 1 or 2 decimal places. With a digital pH meter from Nieuwkoop you are always sure of a good meter to measure the pH value of your (koi) pond.

How does a pH meter work in a pond?

For testing pond water, we recommend taking several samples and then testing them with a pH indicator or handheld meter, as these are very accurate. Measuring the pond water is done as follows:

  1. Take a water sample from the pond with a pipette.
  2. Fill a sample cup with the pond water from the pipette.
  3. Use the digital pH meter/indicator to take an accurate measurement of the water in the sample cup.

Take this measurement in the evening and in the morning. Check that these values are good for koi carp or other fish living in the water.

Which pH meter do you need for your (Koi) pond?

This depends entirely on the desired accuracy and measurement method. We offer a number of possibilities for measuring the pH value in your (koi) pond:

  • The pH test strips.
  • The digital pH indicator.
  • The digital pH meters.

The pH test strips are the most simple way of measuring pH, but at the same time the least accurate measuring method. Our digital pH meters are the best and most reliable solution. In doubt? Our experts are happy to help you with advice on making the right choice!
