Buyer’s Guide- Best Pool Water Test Kit

In this guide, I will share with you some of the very important criteria that you need to consider before purchasing any pool water test kit.

Number of Tests

Most of the pool water test kits have a facility to test between 3 to 11 tests. More the number of tests better the pool water chemistry. 

You should look for the test kit that doesn’t miss the important tests like pH, Chlorine, and alkalinity of the pool water.

It would be an added advantage if the test kit provides you the testing facility for Iron, copper, cyanuric acid & calcium hardness tests. 

Generally, digital test kits offer you more tests than manual test kits.  

Consistency & Accuracy of Test Results: 

Accurate & consistent results are very essential to maintain chemical levels in the pool. If you aren’t getting accurate results then ultimately it will cost you more money.

You’re using expensive chemicals to maintain the chemical level in your pool water. In this case, one inaccurate result misguides you and waste your chemical.

Always invest your money in the test kits that provide you accurate & consistent results.

Easy to Use:

Maintaining pool water is a tedious task. Easy to use pool water test kit makes your task super easy. Test strips are the simplest way to test the pool water while the liquid test kits require 10-15 to test the pool water.

Digital testers are the simplest way to test pool water. Here, you don’t require to compare the colors.

Well Designed:

Finally, you need to think about the design. I love keeping things organized, and many of these products come with cases that you can easily pack when you’re done.

It’s sturdy and sturdy, so you don’t want the pieces to break apart or fall into the pool during sample collection. You won’t want to go fishing, especially in winter.

Good design also means that it is intuitive and easy to use. I don’t like spreading hundreds in front of me while squatting by the pool. Find a well-designed kit that is hassle-free to use.

Sealed Bottle Caps

Pool water test kit that uses chemical which is hazardous so that each reagent bottle solution should come with tight & secure lid.

It could be dangerous if the solution spill and leaves on your skin. Always handle the reagent bottle with care. After using the test kit tightly close the cap of the reagent bottles. Keep it away from the reach of children.

Types of Pool Water Test Kits

There are 3 types of pool water testing kits available in the market are strips, liquid & digital kits. I will explain each of them in brief including the pros & cons in this section.


Strips are super easy to use. You don’t need to take the pool water sample to test it.

Just deep the test strip into the pool water to test it & get the result. To read the result simply, compare the developed color with color chart provided with the kit. 

However, the results of the strips are not accurate as compared to liquid & digital pool testing kits.

You have to store & use the strips carefully because it is contaminated easily. It can’t give accurate results after their expiry.


  • Super easy to use
  • Gives faster results
  • Provide fairly accrate results when you use it correctly


  • easily contaminated even by touching or in presence of moisture
  • It has expiry


As the name suggest liquid testing kits uses liquid reagents which comes in dropper type reagent bottles.

To test the pool water take the water sample in the test vial provided with the test kit and add the reagents using dropper bottle as per the instruction guide of liquid test kit.

This is also an easy to use & less time consuming method.


  • Gives very accurate results
  • Easy to use


  • Provide inaccurate results if you made mistake in adding reagents
  • Little bit time consuming process
  • It has expiry 

Digital Tester

Digital testers provide the results digitally on the screen. You only need to add reagents to test the pool water and you’ll directly get the results on the display of the digital tester.


  • Easy to use
  • Gives accurate results
  • Displays the results on the screen


  • More expensive
  • Periodic calibration required to work properly

How Often Should You Test Your Pool Water?

This is the most common question which confuses people so I will try to clear all of your doubts regarding how often pool water testing is required.

Please note that there are some of the parameters that are very stable & you don’t need to test them daily. 

I will share with you the simple guideline of each testing parameter & required testing frequency.

  1. pH – Daily
  2. Chlorine – Daily
  3. Alkalinity – Weekly
  4. Temperature – Weekly
  5. Calcium Hardness – Monthly
  6. Stabilizer – Monthly

Always follow the above-mentioned pool water test schedule.

Once you know the chemical composition of your pool water, you can reduce the testing frequency of pH & chlorine from daily to weekly. This is in case of cool weather and everything is working fine.

Stick with the daily testing frequency in case of hot weather, after rain, the pool used on a daily basis, or water doesn’t look good.  

How to Use a Pool Water Test Kit?

The first and the most important thing you need to keep in your mind while using the pool water testing kit is

  • keep it out from the reach of children
  • replace all the reagent solutions before their expiry.
  • Store all the reagents in a dry place

Test Procedure:

1. Take the pool water in the test tube provided with the kit.

Dip the plastic test vial into the pool and collect the sample from at least 18 inches depth. Collecting the sample directly from the surface of the pool may not provide accurate results.

Make sure that the sample is filled up to the mark provided in the test vial. Proper sample volume is very important for accurate analysis.

Add the required quantity of reagents using a dropper bottle as specified in the test kit. Swirl the solution for proper mixing, reaction & color development.

Finally, Compare the color with the standard color comparator of the test kit and read the result.

Let’s talk about some popular pool water test methods in brief.

2. Chlorine Test of Pool Water

To test the chlorine add the drops of chlorine test reagents mentioned in the kit. Normally, the Orthotolidin chemical solution provided in the kit for testing of chlorine in the water.

In some test kits, tablets are provided instead of liquid reagents to test the chlorine.

Cap the vial and invert it gently for proper mixing of the reagent with the sample & wait for a few minutes to develop the color.

Finally, Compare the color with the comparator provided with the test kit & note down the result of residual chlorine.

3. pH Test of Pool Water

Take the sample of pool water after properly rinsing the test tube. Add the drops of sodium thiosulfate based reagent to neutralize the residual chlorine present in the water because chlorine will interfere in pH test and gives an inaccurate result.

After neutralizing the chlorine add the second reagent, this will develop the color according to the pH of the pool water. Match the color with the color comparator provided with the test kit.

4. Alkalinity Test of Pool Water

Alkalinity is a simple acid-base titration method. Total Alkalinity represents the acid neutralization capacity of water.

Take the pool water sample in a clean test tube. Add drops of indicator solution provided in the kit and then dropwise add acidic solution till the color changes from yellow to orange.

Count the number of drops you added and calculate the total alkalinity of pool water as per the calculation provided with the test kit.
