Best Pool Test Strips

Pool Test Strips

With regular testing, there is no reason why your pool water can’t be sparkling and hygienic all year round. This is a job made a lot easier when you buy quality pool test strips. Most of them tend to be easy to use and make balancing the chemical levels in your water simple. However, there are a few things to understand before you purchase.

To help make pool maintenance as easy as possible, we have created the following pool test strip buyer’s guide.

What To Look For In Pool Test Strips

Durable Materials

Because they are thin and designed for one-time use, you might think a pool test strip is delicate. This is not the case with a reputable brand as they are made from durable materials so they are not so easy to damage. When a pool test strip is flimsy, it is not so reliable which can be bad news for your water.

Multiple Readings

This is where you can usually tell if a product is worth purchasing or not. You need to be able to take a reading of all the important levels so make sure the brand you are considering has all of them in one strip. A good design is a product that provides a reading for pH, chlorine, total alkalinity, calcium hardness, and bromine.


There is little use in buying a pack of ten test strips as this won’t last you long. Because you should be testing your water regularly, you. need a decent amount of pool test strips available.

Look for a pack of 50 and above as these give you approximately a month’s worth, and tend to offer better value.

Fast Reading

Most products tend to work within seconds, giving you a clear indication as to the chemical balance of your pool. There is no reason for anyone to be stood around the pool waiting for the go-ahead to get on with the next stage of their pool maintenance.

Reading Range

On top of the number of readings a strip can provide, you also need to have a decent range so you can see if there are any dramatic fluctuations in the water.

This will be more important if the water has not been treated for a while. For example, calcium hardness should have a range of around 150 – 400 ppm.

Why Use Pool Test Strips

There are different ways to measure the chemical levels in your pool, but a pool test strip is the most convenient. Being able to dispose of the strip after means you don’t have to look after it for a start.

You can also get lots of readings in one strip, they are easy to use, and produce results in no time.

What Are The Most Important Chemicals Levels To Check For?

There are multiple chemicals you can check for but with four main ones to monitor, make sure your pool test strip will give you a reading for pH, calcium hardness, chlorine, and total alkalinity. 

How Often Should I Check Pool Chemical Balance?

Although some people advise checking it daily, this can be difficult to stay on top of. Let’s face it, a pool cleaner doesn’t go to all their houses every day. 

Because of this, you can do it every other day if it is easier. Whatever you do, make sure you buy a decent-sized pack of pool test strips as you don’t want to go too long between checks.

Are Pool Test Strips Accurate?

Although liquid tests are often popular, a pool test strip is by far the most convenient way of checking the chemical balance of your pool water.

Having said that, they are still known for their accuracy and it is more likely that something will go wrong due to human error when using a liquid testing kit.

What Will Happen If I Don’t Test My Pool Water?

When you neglect the pool water or throw in a random amount of chemicals into the mix, then you are putting yourself at risk of unhygienic water, or a pool that has too many chemicals which can be bad for your skin and eyes.

Testing the water means you get an accurate indication as to the proportion of chemicals to add. If you do not test or add chemicals, then algae will soon form. This is what bacteria clings to and before too long the color of the water will change and it will be unsafe to use.

Also, calcium buildup will be harsh on your poll equipment which can lead to damage. So, testing the pool water is vital if you want to use it for swimming and don’t want costly repairs on your hands.

What Are The Ideal Chemical Levels For A Pool?

Although this can vary slightly depending on who you ask, a general guide to chemical levels for your swimming pool is as follows.

Chlorine: 1.0 – 3.0 ppm

Total Alkalinity: 80 – 140 ppm

pH: 7.4 – 7.6 

Calcium Hardness: 200 – 400

Cyanuric Acid: 25 – 50 ppm

Keep the levels within this range and you will be enjoying a relaxing swim in clear, hygienic water.

Pool Test Strip Vs Liquid Test 

There are benefits to both and ask different experts and different people will tell you they prefer different options. We like the convenience of a pool test strip as it means you can dispose of it after and there is no mixing involved, they are good to go.

This is also what makes them more accurate when it comes to taking a reading. A liquid test is great if you know what you are doing but there is less margin for error. This means you could be adding the wrong amounts because of a false reading.

You also need to stay on top of having enough reagent that is needed to determine the levels.

Pool test strips can expire so this is something you will need to stay on top of but when you get a product with a lengthy shelf life, you are going to find them easier to use than other options.
