Pool Water Testing Kit Buying Guide

Now that we know of the best pool water testing kits, it is time we discuss a few things regarding pool water testing kits and pool water hygiene in general.

Is Pool Water Testing a Necessity?

A lot of people assume that their municipal water is safe as there are rigorous tests done at the plant to ascertain water quality.
Well owners, on the other hand, ignore testing their water with the belief that its natural source is not contaminated.

The truth of the matter is that your water source may be contaminated and the contaminants are transferred to your swimming pool.

Why test well water?

In the case of well owners, the Penn State report is conclusive as to why well water should be tested. In the report, over half of the private wells failed at least one water standard test. But how exactly is well water contaminated?

There are so many ways through which well water gets contaminated. If you have livestock around the well, you should be wary about contamination. Another cause for contamination is proximity to a septic tank, factory, mines, oil rigs, and landfills.

Also, if you use pesticides around the well, or there is a gas leak nearby, there is a high risk of contamination.

Why test municipal water?

There are so many tests performed at the municipal water plant in accordance with the laws and regulations.

However, we have witnessed several cases of municipal water contamination, either at the source or in the main supply’s plumbing systems.

While lead pipes remain banned, over 10 million households in the US are still on lead pipes. This should be a big scare for you and your family. Another thing, the municipal tests, and Consumer Confidence Reports may not be conclusive as the test looks for around 100 pool water contaminants when there are over 100 harmful elements and over 12 dangerous microbes.

Now, which are some of the common elements when it comes to water contamination?

It is important to acquaint yourself with these elements and most importantly, to be aware of the law regarding the maximum acceptable limits.
 1. Fluoride  This is not a serious contaminant and is actually used in manufacturing toothpaste. However, it may be hazardous to your bones. It is not rare to find municipal water with small amounts of fluoride, and this shouldn’t be a concern as long as you keep the limits down to 4.0mg/l as per the federal requirements.

 2. Ammonia  This is a common water contaminant but is not harmful to humans. There are no laws regarding the allowed amount of ammonia. But once your water tests positive for ammonia, you should be worried about the source of contamination. Also, while humans can tolerate ammonia contamination, it takes a toll on aquatic life.

 3. Potassium  Also, potassium is not a poisonous contaminant, and in fact, the human body requires at least 4.7 grams daily. Potassium prevents kidney stones and lowers blood pressure. There are no laws on water potassium levels.

 4. Barium  The source of barium is mineral deposits around the water source, especially wells. It also ends up in the water because of improper drilling, waste disposal, and copper smelting. The effects of barium are grave, and that’s the reason for a strict 2.0mg/l federal limit. Exposure to barium may cause bowel irritations, high blood pressure, brain damage, weekend muscles, and even organ failure.

 5. Lead  In most of the previous cases of mass water contamination, Lead was the main culprit. It is sad that many US homes still rely on the banned lead pipes either in the main supply plumbing or the pool plumbing. The effects of Lead are far much worse than those of barium. It may cause brain damage, attack the nervous system, or cause organ failure. The federal law limits Lead to 0.015mg/l. Lead dust is also a major concern for homeowners with old houses. Before 1978, paints were, and there’s a high chance even the pool or the deck has lead-based paint.

When Should You Test Your Pool Water?

A lot of people have been asking, when should you test your water?

Yes, there are some common signs of contaminated water, but in the first place, it is important to have a regular water testing schedule. So, don’t wait until your pool water starts showing signs of contamination – buy a pool water testing kit today.

Now, back to the main objective of this segment: when should you test your pool water, and what are some of the signals that your water may be contaminated? And most importantly, which test should you perform? That’s what we want to discuss.

  • Recreational Water Illnesses (RWIs) – If you and your family experience recurrent bouts of stomach problems, that is a classic sign of pool water contamination. Honestly, you can’t guarantee that your kids will finish a swimming session without gulping some pool water. I. this case, focus your test on coliform bacteria which is synonymous with most gastrointestinal illnesses.
  • Skin irritations and disorders. The biggest culprit here is pH which leaves your skin dry and itchy. Test your pool water regularly and ensure the pH is balanced. Besides pH, elements like arsenic and barium may lead to skin irritation, cause lesions, and worse, skin cancer. For that reason, you should emphasize on testing your water comprehensively.
  • Lead and corrosion in plumbing – In almost all the water contamination cases, Lead was the notorious element. If you aren’t sure whether your plumbing has lead pipes or it shows signs of corrosion, do a pH, copper, and lead test. Most of the old pools were painted with lead-based paints, and this often leaves lead dust settles at the bottom of the pool. If you’ve had fireworks around, also consider a lead test as the remnants of the fireworks which have Lead might find their way to your pool.
  • Agriculture – Whether you have a garden for intensive farming or you keep livestock nearby, chances are high, your well water may be contaminated. In this case, test for pesticides, nitrates, and coliform bacteria.
  • Saltiness – If your pool water turns salty, your water is contaminated. Your tests should target sodium, Chlorine, and TDS.
  • Scaly residue – If your pool water leaves some scaly residues, consider a water hardness test.

Types of Pool Water Testing Kits

Before you venture out to the market, here are three types of pool water testing kits available and how to use them.

1. Test Strips

These are the most popular testing kits. They are affordable and, but unfortunately, they don’t guarantee 100% accuracy. But that is not to say there aren’t any good test strip water testing kits. Some models are known for high accuracy and efficiency. Strips are best if you want a kit for initial screening or testing for water hardness and maybe pH.

Strips are made from specific materials which, when chemically treated, they react and exhibit a specific color change, thus confirming the absence or presence of certain contaminants. The color change is matched on a color chart to determine the exact contaminant. This method is very subjective just on the fact that the youth and men are not so good at colors.

2. Digital Testers

These are quite complex, and unlike test strips, they probe the water properties that change with the presence and amounts of different contaminants. Digital Testers display the quantities in digits eliminating errors.

But unfortunately, digital testers are not accurate in all tests. Furthermore, TDS (total dissolved solids) tests are not conclusive as they don’t test microbial and lead, which are common pool water contaminants.

3. Lab Test Kits

Experts agree that lab tests are the best if you want to know even the smallest amounts of contaminants in your pool water. Lab test kits have vials where you fill the sample and send it to professional labs. While these tests are accurate, the results are not immediate.

Factors to Consider when Buying Pool Water Testing Kits

There are several important considerations to take into account before adding any pool water testing kit to your cart.

1. Brand

There are so many brands in the market. Always stick to the household names. Avoid the cheap, little known brands. Some of the best pool water testing kit brands to watch out for include: Pentair, PoolMaster, La Motte, and Taylor, just to mention a few.

2. Water source

There are different types of water testing kits. Some are designed to accurately test municipal water while others are strictly for well water. For examples, the Watersafe WS425W is designed for testing only well water so it may not be resourceful in testing municipal water. So, buy your pool water testing kit depending on the source of your pool water.

If you have a well, the common contaminants you are testing for include bacteria, Lead, fluoride iron, manganese, arsenic, nitrite, nitrate, and radiological. You won’t need chlorine tests unless you have disinfected it recently.

For those who rely on municipal water, the standard tests you require are for Chlorine, Lead, and maybe fluoride. There is no urgency of testing bacteria unless there is a scare like recurrent gastrointestinal complications.

3. Self- test vs. lab-test

This is pretty straightforward. If you want to self-test, go for a home pool water testing kit. As for those who would like to seek professional help, There are also lab pool testing kits.

4. What tests?

It is hard to come by a single pool water testing kit that tests the over 100 water contaminants and bacteria. But this is something lab tests can manage.

When choosing a pool water testing kit, make sure you pick the type that is designed to test the probable contaminants in your pool water. There are those which test for heavy metals only while others may be only for water hardness or pH, among other common pool chemicals.

5. Certifications

While brands may promise accurate and reliable results, only independent tests can confirm this. Check out for water testing kits approved by EPA and other trusted independent certifications.

Frequently Asked Questions

1. How often should pool water be tested?

There is no specific timeframe for testing the quality of your pool water. It should just be done frequently to ensure that at no time, your family goes into a contaminated pool. We recommend you test your pool water at least every fortnight, after treating it or when you suspect there is contamination.


3. What is the most accurate pool test kit?

A digital pool water testing kit will offer the most accurate results so here we recommend a model like AquaCheck TruTest Digital Reader. As for the test strips, you are not guaranteed accurate results, but models like Poolmaster 22260 5-Way Test Kit can go a long way in establishing what is contaminating your pool water.

4. How much pool water do I need for testing?

If you use a digital tester or strips, you need only to drop the strip into the pool or wet it. If you have liquid reagents added to water, the average amount of sample is 20-30 ml.

5. Do pool water testing kits show heavy metals?

The majority of water pool tests give you information about standard elements like pH, chlorine, hardness, etc. Only specialized kits show hazardous heavy metals like lead, barium, cooper, mercury. Among the best are ChemCare Heavy Metals test, NovoBlue 14-in-1 kit, Safe Home Starter, and so on.

6. Test strips vs digital testers vs lab test kits: which are the best?

Test strips are the cheapest and clearest way to check you pool water, however you should not that their potency isn`t very accurate. Digital testers are better, but here, you have high porobability of errors and cannot see the level of some elements. The best testing option is lab test kits. They give the widest range of water elements and the most accurate results.

7. How long do pool water testing kits last?

The shelf life of the water tests vary depending on their type and manufacturer. Usually, they are counted on one season. But in case of proper storage, you can keep kits up to 2 years.


There you have it; a review of the best pool water testing kits for home use. As you have seen, digital kits are the best because of the accuracy they offer.

However, if you want to check the quality of your pool water on a budget, get a strip testing kit but remember, it may not be precisely accurate.

So, which is your best option, and why? Talk to us in the comments section below.

  1. Hi! Thank you for the comparison. I just want to know how safe these test chemicals are themselves? I’ve got kids and pets. So are there any official manufacturers’ recommendations.

    • Hi, Eve! Thank you very much for your kind words and question! To test your pool water, you don’t need to add chemicals to the pool. Usually, you take a small amount of sample (into a glass for example) and test it. So, all chemical kits are safe, though you must follow all safety recommendations and keep testing kits out of the reach of children and pets!

  2. Also liked your post very much) We have a small inground pool and add special salt but we need to monitor its level and water condition generally. Does any of these kits may fit us?

    • Hi, Latisha! Thank you very much for your kind words and question! In your case we’d recommend HTH Pool Test Kit 6-Way Test Kit. It works great in salt pools and salt water, tests all main water components and agents. Besides, the kit is quite pocket-friendly if we can call it this way)

  3. Hi everybody! What kit is the best for pH measurement?

    • Hi, EugeneSimon! Thank you very much for your question! pH is the basic water indicator that’s why absolutely all kits test it. Try any of our digital kits.
