Benefits of Pool Water Test Kits

Best Pool Water Test KitWe all know that a pool kit has the purpose of bringing your pool water level at a decent balance – but what you need to understand here is how that balance is achieved. What does it do that makes it such an indispensable tool? Well, here are a few reasons why you might want to invest in a good test kit:

  • Will keep the water from your pool safe from the negative effects of UV rays, which have the ability to harm your body.
  • It allows you to identify the exact number of elements that are found at that point in your pool.
  • A test kit helps you keep the pool clean of bacteria and fungi, telling you exactly when you should add more water or change it completely.
  • It protects you from any allergies or bacterial infections that you may catch from the pool.

Pool water test kits will give you enough data to keep things nice and hygienic – so, make sure that you choose the one that can protect you from anything harmful. Along with the best pool shock and the best algaecide for pools, it will allow you to keep your pool squeaky clean of any harmful elements.

Drawbacks of Pool Water Test Kits

There aren’t as many drawbacks when it comes to pool water test kits – but unless you pick a high-quality unit, there is a chance that you won’t get any accurate results.

Plus, it can be very confusing, as these products are not exactly intuitive. Unless the instructions in the box are clear and straightforward, you might end up getting inaccurate results of your pool.

Last but not least, you need to know exactly what you are testing for: the bromine, the alkalinity, the pH – everything you might deem important at that moment. And once you have used a “tester,” you will not be able to reuse those tests. You’ll have to buy a new kit each time it runs out.

How to Lower the pH Level in Your Pool

No matter where you are living, the standard pH level of a pool is somewhere around 7.0 and 7.8 – but the ideal one (not just standard) sits around 7.35 and 7.45. This is the kind of level that will prevent problems such as red eyes or itchy skin. If you see that you are suffering after each swimming session, then you might want to consider fixing the pH level of your pool.

To lower the pH level of your pool, you will first need to test it. This is exactly where pool testing kits come in, as they will tell you what is wrong with your pool. Based on the results, you will know what step you have to take first.

If the pH level of your pool seems to be way too high (for example, going over 7.8), then you might want to begin adding pool acid. Do so until the number is as close to 7.4 as possible – the ideal pH level. These acids will vary on your possibilities and personal preferences – but you may go for sulphuric acid, hydrochloric acid, or sodium bisulphate.

If the opposite happens and your pool pH is very low (in need of being raised), then you will have to add a strong alkali until it goes all the way to 7.4. These alkalis may include the “buffer” (sodium bicarbonate), or the “soda ash,” (sodium carbonate).

Types of Pool Water Test Kits

Benefits of Pool Water Test KitIn order to make sure that the reading is accurate, you have to understand that there are various types of pool test kits available. All of them have various uses and features, and they will generally measure using different methods. Here is what you might want to look out for:

  • Digital Kits: These kits provide a number reading using a digital sensor – and are generally among the easiest to use.
  • Turbidimetric Kit: This kit allows you to measure the cloudiness of the water.
  • Photometric Kit: As its name suggests, this type of pool test kill will use a photometer to calculate the readings of the water.
  • Titrimetric Kit: With this kit, you measure the change in the color of the water.

It may seem like these pool testing kits have only one operation – but in fact, they are highly versatile. Usually, these items have the ability to show more than one calculation at the same time. You may find out more about these types of kits by browsing through our Pool Guides homepage, as we provide all the information that you need about maintaining your pool.

Features to Look for When Buying a Pool Water Test Kit

When it comes to buying a pool water test kit, we all know that it is not an easy task to do. Every manufacturer will swear by their product that it is the best on the market – but even a good product might not be enough if it does not have the features and qualities that you are looking for.

In order for its purpose to be fulfilled, here are the things that you might want to look out for. Most of them can be determined by reading reviews – but the product description might also be very useful in this regard.

  • Accuracy

The most important feature to look into a test kit for pool water is certainly its accuracy. If it does not provide good readings, you may end up leveling the pH wrong – which can be very bad for you.

For this reason, you might want to stick to a true and tested kit – one that has received all the good reviews. Look for a trusted manufacturer – because if it is popular, there is a reason for that. If the manufacturer has been active for a while – and still manages to keep its customer base – then it means that it is probably doing something right.

Depending on your preferences, you may use a liquid test kit (which tends to be more comprehensive), or a test strip (which is very quick and easy to use).

  • Ease of Use

Needless to say, when you buy a pool water testing kit, you need something that you can use easily – and not stare at it for hours, unaware of how you are even supposed to use it. No matter how good the kit is, if it’s just sitting on the shelf, then it’s just wasted money.

  • Completeness

The basic test kit will contain a sanitizer test, a pH level test, an instruction slip, and the recommended range for every measurement. However, better tests will include alkalinity tests and calcium hardness tests. This will make your testing session as accurate as possible.

You can also opt for chlorine tablets for pools and the best way to pick them is by reading our complete guide and reviews. Cloudy water in your pool will be no more.

  • Durability

Can your testing kit withstand consistent use in the pool? To determine whether it can or not, you should check if it has waterproof instructions, and whether it has vinyl reagent labels or not.

  • Availability

You may be using a fancy pool testing kit that provides all the right data – but if it’s next to impossible to find refills in your area, then this might not be the right product for you. No matter if you buy from a local shop or online, make sure that you have where to buy your refill from or where to buy any potential replacement parts.

  • Results Consistency

The primary purpose of buying a pH level water testing kit is to catch a problem before it even gets a chance to develop. Therefore, it should be able to provide accurate, consistent results even after months of use. This is not something that you’ll be told by the manufacturer, as everyone will boast fair consistency. However, you should be able to get a good idea of its consistency by reading through the reviews.

  • Design

You might think that design is actually not as important – but in truth, it is. If the design is not right, not only may it provide inaccurate results, but it will also be very troublesome to deal with. The smarter the design, the less hassle it will cause.

For example, liquid reagents will have to leave no waste, nor should there be other materials that you need to dispose of afterward. The color standards should also be protected from scratching or bleaching.

Make sure that the fill marks aren’t painted – and are instead molded on. Plus, since you will likely be carrying that test kit around, you should ensure that it is portable. Look for ergonomic handles on the case to ensure easy transportation.

  • Value

Like with any type of purchase, you need to ensure that it provides value for the price that it is sold at. No matter if it is sold at a budget price or it is slightly more expensive, make sure that it has all that you need and that you get your money’s worth from its features.

Moreover, such a kit does not have to be expensive. There are many reputable manufacturers that are selling their products at a good price – while providing great efficiency in return.

How to Test a Pool with a Pool Water Test Kit

Pool Water Test Kit ReviewsThe testing should depend on exactly what you are planning to test. Chlorine and pH levels require a daily test, temperature and alkalinity need a weekly test, and calcium hardness needs a monthly test.

To test the water, you will first have to get the correct vials and strips for your pool. Sure, you may dip that strip into the pool – but it’s much easier to simply collect it in the vial and do the testing in a safe environment. This will ensure that the readings you get are actually constant. You either dip the strip in the vial or you add a few drops from the reagent necessary to conduct the test – the result being a change in color that will tell you what is wrong.

Make sure that the water you test is taken from an elbow-deep level. You don’t want to take it straight from the surface, as the results might end up being inaccurate. With a strip test, in about 15 seconds, you should have your results.

Maintaining Your Pool pH Level

You can automatically control the pH level in your pool by opting for the best pool saltwater chlorinator systems. These will be fitted to your pool and will add either pool acid or chlorine at a regular interval.

Most of the older models are pre-programmed by users after they have conducted various strip tests. However, newer models can automatically detect these levels – and will send the chemicals accordingly.

These systems have the ability to make this balancing act a much easier process – but you should not rely on it completely. To keep yourself and everyone else safe, you should still do a weekly regular check of the pH level of your pool.

Safety Tips to Consider when Using the Kit

When it comes to safety tips, there are not many things to cover – at least nothing that does not involve common sense. First things first, when taking out the water from the pool, make sure that you do not lean in too much on the edge of the pool. It’s great if you jump properly for a swim – but if you fall awkwardly while “fishing” for water, you might end up injuring yourself.

This goes without saying, but you should not let the substances for testing the water level touch anything near your face. Do not swallow or lick, and do not let the liquids anywhere near your eyes. If you are feeling particularly clumsy, then it might be a good idea to add some safety goggles in the mix.

Gloves can be good, too, particularly if you have sensitive skin – but make sure that they are not too thick. Otherwise, you might have difficulty in handling the vials.

Wrap Up

Many brands promise to offer the moon and the stars, but not all of them provide the same efficiency. The more complete a testing kit is, the more value you should be able to reap from it.

The best pool water test kit should be easy to use and should provide accurate readings. It should also come with clear instructions so that you can immediately understand the readings. This applies particularly to color-based tests since each test will have its own color code.

Hopefully, our pool water test kit reviews have allowed you to make a calculated decision over which set is more appropriate for you. As you can see, they are sold in various mixes – and all that matters is that you pick out the one that is most convenient for you.
