Shopping for the quickest and easiest way to test your pool’s chemical levels?

You’ve found the right place!

The majority of experts recommend pool owners shock their pool every week. However, that alone is not enough to keep your pool healthy and beautiful. Excessive use, signs of algae, and heavy rainfall might demand extra maintenance and care.

If you want to manage your pool water’s chemistry, then it’s essential that you test it regularly to ensure it’s safe to dive in. That’s where pool testing kits come in. By using a quality test kit, you can determine the quality of your pool water. This will give you an idea about the care and the chemicals your pool water needs.


What’s In This Buying Guide?

It’s important to remember that all swimming pool testing kits are not made equal. To help you make the right choice, this guide includes reviews of some of the best kits on the market, how to use them, and the factors to consider before purchasing them.   


Why do you need a pool testing kit?

To ensure that the water in your pool is chemically balanced, safe, and clean enough for swimming, you’re going to have to use a testing kit regularly. Even if the water seems healthy and clear, its chemistry may be off. This might damage the pool equipment and may make the pool unsafe for swimmers.

That’s why a quality pool testing kit is one of the most valuable items owned by a pool owner. It can check your pool’s levels of pH, calcium hardness, free chlorine, total alkalinity, cyanuric acid, and much more. If you own a saltwater pool, then it’s advisable to get a kit that tests the salt level as well.

Another reason for purchasing a pool testing kit is that it offers similar instructions for all included chemicals. In simpler words, if you purchase a liquid pool testing kit, all the included chemical tests will work in pretty much the same way, and you’ll understand how to use them properly fairly quickly.

However, if you purchase separate tests for every chemical, you’ll need to learn how to read and use each one.

Limitations

  • Expensive than other models.
  • The digital display can develop issues over time.
  • This kit does not come with a guide for understanding the different ranges, so it can be difficult to determine whether your pool needs anything or not.

How to Select the Best Test Kit For Your Pool

Although it’s not difficult to choose a pool kit that’s suitable for your pool, there are still some factors you should consider before finalizing your purchase:

Type of tests

There are three types of pool testing kits available today: digital, strips, and liquid tests. Each type has its own advantages and disadvantages, so make sure you choose the one that best suits your needs.

Liquid

A liquid test kit works with reagents, which is basically the liquid that’s filled in the dropper bottles. To perform this type of test, you’ll need to take a water sample from the pool and add the required amount of reagent into the vial of water. Most models come with instructions that tell you how to properly take the readings, but they’re generally very easy and take little time.

These models provide incredibly accurate results if used properly and are very easy to use. However, they can expire and give inaccurate results if they’re not used properly.

Strip tests

Although strip tests are extremely easy to use, they’re not as accurate as other types because they can easily be tainted and don’t work if they expire. With strip tests, you don’t need to take any samples. Instead, you just need to dip them directly into the pool water and wait a couple of seconds for the strip to change color. Typically, each color specifies a different level, so you need to read the included instructions to determine what each color means.

Along with being simple to use, strip tests are also fairly accurate if used correctly and faster than liquid tests. However, they can expire, and you can easily contaminate them with moisture or by touching them.

Digital

Similar to the liquid pool testers, digital types also use reagents, but they’re easier and quicker to read as the electronic device does all the work for you. While they’re extremely accurate if used correctly, they can be costly and need to be calibrated after every few uses.

Test Consistency and Accuracy

Several models in the market will give you inaccurate results. To get a precise and accurate reading, the test needs to be administered properly, but sometimes the problem can be faulty or defective equipment. All the kits mentioned above are extremely accurate, so feel free to choose one of them.

Number of tests

Generally, a kit with more tests will give you better value for money. Most units mentioned above cover all the basic tests.

Ease of use

Maintaining a pool can feel like an extremely tiring chore, so it’s important you choose a pool testing kit that’s easy and simple to use. Basic pool test strips are incredibly easy, as you just need to dip them in water, wait for them to change color, and compare them to the included color spectrum.

Digital readers are simpler than test strips, as you don’t even have to compare colors. If you don’t want to fiddle around with numerous different reactions, both these options are perfect for you.

Design

If you like staying organized, then it’s advisable to choose a unit that comes with a case, so you can quickly pack your stuff up once you’re done. If you’re leaning towards a liquid test kit, make sure that the included vials are sturdy and strong, so they don’t break while you’re collecting samples.

A quality design also means that the kit should be straightforward and intuitive to use. Therefore, choose a unit that doesn’t have you spreading a thousand things in front of you while you’re sitting next to your pool.

What are the ideal pool chemical levels?

The best way to calculate specific chemical levels in your pool water is to use a pool testing kit. By checking the pH balance and the chlorine levels of your pool, you can ensure that the pool is healthy and safe for use.

But what exactly are the appropriate chemical levels that make a pool safe? There is a bit of difference of opinion among pool experts on some of the chemical levels, but most of them agree that the ranges you should aim for are:

  • Chlorine: 1-3 ppm
  • Calcium Hardness: 200-400 
  • pH: 7.4-7.6
  • Total Alkalinity: 80-140 ppm
  • Cyanuric acid: 25-50 ppm

Why it’s important to test your pool water regularly

If you don’t use a test kit, you’ll have no choice but to guess the number of chemicals that need to be added to the pool water. If you begin guessing, it’s highly likely that you’re going to add the wrong amount.

One of the most important responsibilities of a pool owner is to regularly test their pool’s water quality. You need to check whether the water is safe to dive into and whether the pH levels are within the recommended range.

If your pool water has unbalanced chemistry, it will damage both the swimmers and the swimming pool.

Balanced water chemistry stops the growth and spread of slimy algae on the pool sides, keeps your hair from changing color, and prevents calcium buildup from damaging your equipment.

If your pool water has a low level of chlorine, it will lead to the growth and spread of algae blooms and other bacteria. On the other hand, high chlorine levels can result in eye and skin irritations. Similarly, unbalanced pH levels can erode your pool liner and pool equipment, while high calcium levels can lead to scaling and the clogging of your filters and pipes. It’s also important to remember that unbalanced total alkalinity levels can affect pH levels, which can, in turn, affect the calcium hardness levels.

Since everything goes hand in hand, you must test your pool water for all these chemicals regularly. It’s advisable to perform tests weekly unless you have certain problems, like algae growth. In that case, you need to test your pool water regularly until all chemical levels are within the right ranges.


Final Verdict: What is The Best Pool Kit?

Choosing the right pool testing kit is not a difficult decision. These kits are available in almost every price range, so you don’t need to worry about your budget. However, it’s advisable to spend a bit more initially, so you have a high-quality kit that lasts you more than a few years.

We find the LaMotte ColorQ Pro 7 Digital Pool Water Test Kit to be the best overall option because of its ease of use, long-lasting chemicals, and digital tester. If you can’t decide which pool testing kit to purchase, the LaMotte is a relatively safe option.
