Top 10 Pool Test Kits Reviews and Buying Guide – 2020

When you think swimming pools, what comes to most people’s minds is fun and lots of it! A swimming pool is an excellent place to spend time with family and friends. With lots of games to play and that awesome weightless feeling, you get while just floating on water.

To continue enjoying the immense pleasures that come with owning a swimming pool, you need to not only clean it regularly but also keep the water healthy. Regular testing is required to achieve this.

You might think that testing your pool is a difficult task that requires professionals, but on the contrary, it is a pretty easy task. Anyone can do it. It takes about half an hour or so; then you’re all done.

To fully appreciate the value of testing your pool, you need to know the advantages that come with doing it and the types of chemicals in your swimming pool that require regular testing and control over.

Chemicals found in swimming pools

In ensuring safety, it is crucial to ensure your swimming pool remains balanced. The following compounds are found in your pool:

I. Bromine

The purpose of bromine is to stabilize the PH level and acidic level by ensuring the water does not become too acidic.

II. Sodium bicarbonate

Sodium bicarbonate raises the level of alkalinity in your swimming pool.

III. Calcium hardener

It increases the level of hardness of calcium in your pool.

IV. Chlorine

Chlorine often comes as a trichlor or dichlor. Their purpose is to chlorinate your swimming pool. Their main difference is that trichlor has to be attached to a chlorinator while dichlor doesn’t.

V. Cyanuric acid

Its primary purpose of cyanuric acid is to stabilize the level of chlorine in the pool and to protect it from UV rays.

Advantages of testing your pool

1. It increases the lifespan of your pools equipment

Swimming pool equipment such as hot tubs and the pool itself are expensive investments. Being as expensive as it is, it is essential to make it last as long as possible. After all, you wouldn’t like to see your hard-earned money go down the drain, would you?

After a while of usage and with the frequent addition of chemicals, pool water becomes corrosive. Corrosive water rusts metal (pumps and heaters); it degrades rubber o-rings, causes the plastic to become brittle, and can even cause hits to form in the concrete finish of swimming pools.

Scale forming water may also reduce the efficiency of your heater leading to higher electric bills as it takes more time for water to heat when scaling forms on the surface of water heaters.

2. Leads to more comfortable bathing water

Itchy skin and red, irritated eyes are common indicators of poor water PH balance. The PH of swimming pool water needs to be maintained at 7.5 PH value; this is the PH of the human eye. Keeping it at this level reduces eye irritation.

Excessive amounts of chlorine and bromine cause skin to itch. It is therefore critical to test the water and add a bromine/chlorine neutralizer to bring down the sanitizer level to the recommended level of 1-3 ppm of chlorine and 3-5 ppm of bromine.

3. Makes the water safer to swim in

Untested water is very unsafe as it may result in the development of rashes and other water-borne infections. The health and safety of those close to you are of utmost importance.

Regular testing prevents the accumulation of toxins that would harm those swimming in the pool.

4. Regular water testing saves you money

It makes you glad to hear that, right? Everyone loves their money, and every chance to take to keep it ensures you don’t go broke anytime soon. The cost of testing and treating water is greatly outweighed by the expenses associated with unbalanced water.

The extra expenses that could be incurred as a result of unbalanced water are; reduced equipment life and treating problem water, like green water, which could take hundreds of dollars.

5. Maintains water balance

Proper water balance results in zero problems with your pool. Water balance and testing are essential because:

I. It enables the sanitizing chemicals to work effectively.
II. Lessens the chance of water problems including cloudiness and algae.
III. lengthens the lifespan of your equipment.

Ideal chemical levels for your pool

  • PH: 7.4 to 7.6.
  • Alkalinity: 80 ppm to 140 ppm.
  • Chlorine: 1.0 to 3.0 ppm.
  • Calcium hardness: 200 – 400.
  • Cyanuric acid: 25 – 50 ppm.

Types of pool test kits

There are three types of toolkits available. All have advantages and limitations, though. They are:

  • Liquid
  • Digital
  • Strips
  • Combination meters

1. Liquid

Liquid test kits use reagents that come in dropper bottles.
To use Liquid test kits, first, take a vile of pool water to be tested then add the prescribed amount of reagent.

All test kits come with instructions on how to take readings. Taking readings is quite simple and takes very little time.


  • Easy to use
  • Provide accurate results when used properly


  • If not handled properly, they can give inaccurate results
  • Takes time to test all chemicals
  • They can expire

2. Strip tests

These are by far the most accessible tool Kitts to use. To test the water, you simply dip them directly into the pool water hence eliminating the need to take samples.

The next step in the testing process is to wait for them to change color then read instructions given on how to take readings.


  • Very simple to use
  • Faster to use than liquid tests
  • Fairly accurate when used correctly


  • Can get easily contaminated by moisture
  • Can expire

3. Digital

Like the liquid types, they use reagents. They are much easier to read as the electronic device displays the readings on a small screen.


  • Easy to use and read
  • High level of accuracy when used correctly


  • They require regular calibration
  • Are more expensive than other testers

4. Combination meters

The use of combination meters is the most accurate way of testing your pool. They use a combination of the test strip and liquid with computerized tests and readout.


  • Are very accurate


  • Are expensive

Tips on how to effectively test your pool.

1. Integrating technology into your water testing routine

Advance in technology has led to the innovation of many techniques that assist in pool testing, including digital test kits and Smartphone apps that read your testing stripes, provide treatment plans, and track water readings.

Integrating technology into water testing routines is the best option for beginners who need further instructions or for seasoned pool owners who don’t want t waste time.

2. Don’t use strips from a different season

Testing strips generally have a service time of one season as they are damaged by moisture. Continued use of old testing strips leads to false, inaccurate results.

Old testing strips should be appropriately disposed of and replaced with new ones.

3. Wait a few seconds before reading the test strip

Although test strips change color almost instantly when placed in pool water, you should wait for at least 20 – 30 seconds before reading your test strip. The extra time allows for levels and colors to properly develop, thus eliminating the possibility of false reading and wrong water treatment.

You should also make sure you correspond the colors to their correct match. If the color is unclear, do the test again and wait for the suggested time before taking your new readings.

4. Test level of chlorine in the morning

During the day, UV light causes chlorine to dissipate, thus altering its levels and affecting results. The chlorine levels should be tested in early morning hours. If that is not possible, adding cyanuric acid will stabilize chlorine and minimize the harmful effects of sunlight.
