How to Test Pool Water: Step by Step

Your pool is your pride and maintaining it properly is your responsibility as the pool owner. And of course, you do maintain it to make it crystal clear and algae free. But it’s also important to maintain an optimum balance of chemicals in your pool to prevent damage to your pool and equipment.

It’s also important to maintain water quality and standards of your pool to prevent problems like eye irritation, hair discoloration, for the ones who dive into it. So, it’s important that you do water testing for your pool and makes sure no contaminants are present and the chemical levels are balanced and within the set standard limits.

Keeping that in mind, here we have come up with a brief guide on what to do to test your pool water accurately.

Why Pool Water Testing is Important?

Pool water may look clear and safe but there are several chemicals present in your pool that should be maintained at ideal levels to prevent contamination. The same chemicals that can make your pool water safe, can also make it potentially dangerous if not balanced.

Testing your water is the only way to make sure that the chemicals in your pool are maintained at optimum limits and your pool is safe.

How Often to Test Your Pool?

You should test your pool water often. It might sound like a hassle, but it will save you a lot. Because the better balanced your water is, the less cleaning and changing.

A good frequency of water testing for your pool is once a month. Also, you should test it when you open and close it for the season.

The chlorine, alkalinity, and pH levels should be tested regularly. Chlorine and pH together form what we generally call the ‘disinfecting team’ of your pool. So, the minimum testing schedule for pH and Chlorine is weekly.

There are some other times when you should test your pool water for balanced levels of chemicals, such as:

  • After the pool is used by a large group
  • After a rainstorm
  • Before any form of algae treatment
  • After the water is added
  • After changes in weather
  • When you notice any issues with your water, like cloudiness and color changes

What Chemicals to Check in Your Pool?

The main chemicals that you need to check in your pool are the pH, alkalinity, calcium hardness, and chlorine. In some situations, you may also need to check for metals and stabilizers. Given below are the details of the chemical levels to maintain a balanced pool.

Test            Range

pH            7.2 – 7.6

Total Alkalinity        120 – 150 ppm

Calcium Hardness    200 – 250 ppm

Calcium Hardness    175 – 225 ppm

Free Chlorine        1 – 3 ppm

Free Bromine        3 – 5 ppm

Copper            0 ppm

Iron            0 ppm

CYA            30 – 50 ppm

Procedure to Test Your Pool Water

First comes gathering the sample. Use a clean test container to collect the water sample. Hold it in your hand and push it inside the pool with the opening facing downwards. Now, slowly turn the container upwards and water will be filled inside it.

Now, you can do two things to test your pool water collected. You can either test it yourself with the help of liquid test kits or test strips or rely on a professional to test your pool water sample for any type of chemicals and contaminants.
