Poolmaster Essential Collection Chemistry Case (22260) 5-Way Swimming Pool & Spa Water Test Kit, Small, Neutral

see-it-on-amazon

Poolmaster 22260 is one of the most popular and highest rated pool test kits for sale anywhere. It is a 5-way kit that tests for pH, chlorine, bromine, acid demand and total alkalinity.

For most residential swimming pools, these tests are enough to maintain proper water chemistry.

The Poolmaster 22260 is easy to use even for first-time pool testers.

If you depend on your pool guy or a pool service to test and add chemicals to your pool, this kit will let you to do everything on your own.

It consists of a test block with UV-protected color chips that provide an accurate reading.

Just add water to the test tubes and add the reagents as instructed. The instructions for taking various tests are very clear. You don’t need a chemistry major to test how acidic or alkaline your pool is.

The reagents last on average 2-4 seasons depending on how often you test your pool.

If your pool is used daily, it is a good idea to take a chlorine test once a day because it is by far the most important chemical for maintaining a healthy pool.

As for the other tests, you can do them 2-3 times a week.

Pros

  • Easy to use a test kit, even for beginners. The detailed instructions are very helpful.
  • Accurate test readings
  • Long-lasting test chemicals
  • Everything is neatly organized in a durable polyethylene case
  • Great price – the Poolmaster22260 is one of the most affordable 5-way pool test kits

Cons

  • Not ideal for special situations. It lacks tests for calcium hardness, cyanuric acid, and other chemicals.

2. Best for Home & Commercial Pools: Taylor Service Complete Pool Water Test Kit K-2006C

Taylor Service Complete Pool Water Test Kit K-2006C

see-it-on-amazon

If you want a comprehensive test that analyzes your pool’s complete chemistry, this is the best test.

This kit is good enough for commercial pools, too.

Here are the things you can test for with the Taylor Service kit:

  • Free and total chlorine
  • Bromine
  • pH
  • Acid demand
  • Base demand
  • Total alkalinity

3. Best Value: LaMotte 2056 ColorQ Pro 7 Digital Pool Water Test Kit

LaMotte 2056 ColorQ Pro 7 Digital Pool Water Test Kit

see-it-on-amazon

If you find that comparing the color of the water to the color on the chart to be tedious or confusing, get a digital pool water tester.

A digital test kit is also great for colorblind persons because color matching isn’t needed to use it.

The LaMotte 2056 ColorQ Pro is also one of the best affordable digital pool testers.

It uses a photometer to measure changes in the water after you add a reagent, then gives you a digital readout on a small screen.

Using a digital test is so much easier and more accurate than trying to figure out where on a color chart your results fall.

ColorQ Pro can measure seven different aspects about your pool water, as follows:

  • Free Chlorine
  • Total chlorine
  • Bromine
  • pH
  • Alkalinity
  • Calcium Hardness
  • Cyanuric acid

The ColorQ Pro is a great choice if you want to do a comprehensive chemical analysis of your pool.

Being a digital kit, you will not use a comparator block – that thing with the two tubes and a color chart used in traditional kits.

Instead, the ColorQ Pro kit includes the digital tester itself plus the reagents you’ll need for the seven tests.

There are instructions included that explain how to carry out each test.

The only thing missing is a guide for interpreting different ranges so that you know whether you need to add anything to the pool.

But you can easily get the correct ranges online or calculate them at PoolCalculator.com.

Pros

  • Takes the guesswork out of pool testing
  • Great for colorblind persons
  • Comprehensive pool testing
  • Easy to use
  • Includes a carry/storage case

Cons

  • No chart or guide to provide target range recommendations
  • More expensive than a traditional color-matching kit

4. Easiest to Use: SafeDip 6-In-1 Electronic Pool And Spa Water Tester

6-in-1 Electronic Pool and Spa Water Tester

see-it-on-amazon

The SafeDip electronic water tester works differently from digital testers. It uses probes instead of a photometer to test various water parameters.

You don’t need to add reagents to the water. Just scoop pool water into the sample cup and dip the tester inside.

The SafeDip measures all parameters at once, making this the easiest pool testing kit we know of.

As a bonus, you never have to worry about replacing reagents.

Here’s a video showing how it works.

The SafeDip electronic pool water tester measures six things:

  • pH
  • Salt
  • Chlorine
  • Total dissolved solids (TDS)
  • Temperature
  • ORP (oxidation-reduction potential)

The SafeDip tester does a great job measuring pH, salt, temperature, and TDS (total dissolved solids).

But it is not the best for measuring chlorine.

For one, it does not give precise chlorine level numbers; only a reading of low, good or high.

That’s because it measures chlorine levels indirectly by measuring ORP, which is the ability of chlorine to oxidize pool contaminants. Higher ORP correlates to higher chlorine levels.

But this method is indirect and not as accurate as measuring the chlorine itself.

Another downside is that it doesn’t measure alkalinity, one of the most important parameters in pool maintenance.

For these two reasons, we recommend the SafeDip only for those who want a quick and easy way to measure pool pH, chlorine salt, temperature, and TDS.

Once you get your measurements, go to safedip.com and enter your values in the calculator to get recommendations on how to balance your pool’s chemistry.

6. Most Accurate: LaMotte ColorQ Pro 11 Digital Pool Water Testing Kit

LaMotte 2060 ColorQ Pro 11 TesTabs Swimming Pool Water Test Meter Kit

see-it-on-amazon

Seven tests not enough for you?

The LaMotte ColorQ Pro 11 lets you test 11 parameters.

  • Free and total chlorine
  • Bromine
  • pH
  • Total alkalinity
  • Calcium Hardness
  • Cyanuric acid
  • Iron
  • Copper
  • Biguanide
  • Biguanide Shock

The last two apply only to Biguanide pools. These are pools that use Biguanide instead of chlorine to disinfect the water.

The kit also tests for iron and copper, two tests you cannot find in most pool water test kits.

The LaMotte ColorQ Pro 11 is designed mostly for professional pool services and pool managers. But there is no reason you cannot use it for your home pool, especially if you want in-depth testing.

As with ColorQPro 7, the Pro 11 is a digital tester. It uses a photometer to measure changes in water after you add a reagent and then provides a digital readout.

This digital test kit is great for those who are colorblind or find color charts confusing, inconvenient or time consuming.

ColorQ Pro 11 is one of the best pool testing kits sold anywhere. The only reason we hesitate to recommend it wholeheartedly is a common complaint from many users.

After a while, the kit tends to display an “Err 7” message. The company says this is caused by a dirty lens.

After cleaning the lens, the error usually goes away, but the kit may then begin giving inconsistent results.

If you decide to buy this kit, you might want to talk to the manufacturer for advice on how to avoid this error and how to resolve it.  There is a solution – but again, this one is for more advanced users.

The warranty is also fairly short – only six months – so you may have to pay a fee to get the error resolved if it occurs after six months.

Pros

  • Easy to use – no confusing color matching
  • Ideal for colorblind persons
  • Comes with a hardy carrying case
  • Does more tests than any other kit

Cons

  • A problematic error code may occur after several months.
  • Short warranty period

Types of Water Testing Kits

Poolmaster Essential Collection Chemistry Case (22260) 5-Way Swimming Pool & Spa Water Test Kit, Small, Neutral

Pool Test Strips

Pool test strips are the easiest, quickest and cheapest way to test your pool water. They are fairly accurate but not as precise as liquid and digital test kits.

Test strips come with a color chart that you match the strips to.

This gives you the pH, alkalinity or acidity level. You can also use strips to test for specific chemicals like chlorine, bromine or water hardness.

You can buy strips for a single test or a pack for multiple tests.

Liquid Test Kits

Liquid test kits are more reliable than test strips.

Instead of dipping a strip in the water, you add a chemical reagent to water in a test tube and match the color change to the color chart.

For some tests, you count the number of drops required for a complete color change.

A liquid test kit will have several reagents for multiple tests.

There are two types of liquid test kits.

Liquid test kits with the color chart: These are basic kits where you have to match color changes to a chart. These kits are cheap but can be difficult to use for people who suffer from bad eyesight or color blindness.

Digital liquid test kits: Instead of matching colors, digital liquid test kits do the reading for you. After you add the reagent to the water in a test tube, you insert it into the digital unit that has a photometer which detects changes in the water. It then provides a precise digital reading on a screen.

Electronic Test Kits

An electronic test kit does not use reagents. Instead, you insert probes into a water sample to get instant readings.

Most electronic test kits provide accurate measurements for pH, TDS, salt, and temperature but tend to be less precise when it comes to measuring chlorine.

Electronic pool testers are the easiest to use. You do not have to add reagents, and you can get multiple readings at once.

Of course, they are more expensive than other types of pool testing kits.

The best choice among these three depends on your needs.

If you want a fast and cheap way to test your pool, get test strips.

If you want a more accurate but affordable testing method, get a liquid test kit.

If you are color blind or have trouble matching colors, get a digital liquid test kit or an electronic test kit. The latter is also the best if you want the most accurate readings (except chlorine – a liquid test kit is the best for chlorine testing).


How to Use a Pool Test Kit to Get the Most Accurate Results

Poolmaster Essential Collection Chemistry Case (22260) 5-Way Swimming Pool & Spa Water Test Kit, Small, Neutral

Here are some tips on how to use a pool test kit to get the most accurate results.

  • Read the instructions before you do anything. Focus especially on how to use the reagents. Adding the wrong reagent or using more than the recommended drops will give you the wrong readings.
  • When taking a water sample from the pool, dip your hand up to the elbow. Do not scoop water from the surface, near the skimmer or the return line.
  • If you are using a liquid digital test kit, wash the tube between tests or use a new tube to avoid contaminating the water.
  • Use the white placard included in your liquid test kit to better see the watercolor and match it to the chart. If your kit does not have the card, use anything else you have on hand like a white sheet of paper to create a white background.
  • If you are color blind or are not sure about the color, get a second opinion. If you are color blind, we highly recommend buying a digital liquid test kit or an electronic test kit.
  • Do not use fingers to cover the tubes when mixing water with the reagent. Oils from your skin can affect the readings. Either jiggle the comparator to get a good mix or, if you are using a digital tester, use the included caps to seal the tube then mix.

Frequently Asked Questions

pool chemical test kit

How long are pool test kits good for?

Check the expiry date on the reagent bottles. Most test kits last between 1-2 seasons after which they lose their strength.

Store reagents in a cool, dry place away from sunlight or temperature extremes.  Don’t store them in your pool box.

Can I use reagent from another company with my test kit?

No. Different companies formulate reagents differently. Only use reagents from the kit manufacturer to get accurate readings.

What is the best pool test kit?

A liquid pool test kit is usually the best choice for most people. It’s affordable, reliable and fairly easy to use.

Which is the best pool test kit for color blind people?

A digital liquid test kit like LaMotte or an electronic test kit like SafeDip is the best choice for colorblind people because it does not require you to match colors.

What is the best salt water pool test kit?

All pool test kits work the same for both freshwater and saltwater pools. If you want to monitor salt levels, get a pool test kit that tests for salts such as the SafeDip 6-in-1 tester.

How many drops do you put into a pool test kit?

It depends on what you are testing for.

For chlorine, you usually add five drops of the chlorine indicator reagent.

For pH, you first add one drop of chlorine neutralizer, then five drops of red phenol indicator.

For the acid demand test, you add drops until you get a permanent color change.

Check the instructions for the precise number of drops you should add for each test.
