When To Test Your Pool More Often

How to test your pool water the right way

You may need to test your pool water more often depending on how much you swim, who uses the pool and what the weather is like. When youre going for a dip or swimming laps more than once a day, measure the free chlorine four to five times each week.;

If pets or little kids use your pool, you should also be testing the free chlorine four or five times each week. Pets and kids are more likely to go to the bathroom in the pool, which affects the chemical levels greatly.;

Having a pool party? Test the pool water before your guests arrive and after they leave. The more people who use the pool, the more the chemical balance will be affected. Taking measurements prior to the party and afterward will help you see exactly how the numbers change.

When it rains, a lot of fresh water can end up in your pool, which can make the water more acidic. After a storm passes, test your pool waters free chlorine and pH as soon as possible.

Regular pool water testing lets you know which chemicals need to be adjusted. Keeping the right chemical balance may require you to check your pool water as often as every few days.;

Have plenty of pool test kits or pool test strips ready to use throughout the swimming season. The Home Depot delivers online orders when and where you need them.;


How To Test Pool Water Accurately

It doesnt seem like it should be a complicated endeavor, and its really not. You even have a few testing options:

  • Use test strips; quick and easy
  • Take a water sample to your local pool store; the most thorough and accurate

How hard can it be, right? Theres just one key to making sure youre testing pool water accurately: the water sample.

Check For A Leak In The Electrical And Filtration Systems

Its easy to check the electrical and plumbing systems for leaks. Look at the electrical conduit lines that lead from the pools lights for moisture or leaks. There shouldnt be any water on the wires. If there is, call a professional to determine the precise location of the leak and repair it — you dont want to get shocked.

To see whether your pools water system is leaking, turn off the filtration. Look around all pipes, fittings and the pump for moisture. If you see any, this is likely the location of your leak. Depending on the exact location of the leak, you may be able to replace a pipe yourself, or, for more complex issues like a failing pump,;you might need to have a professional service your pools filtration system.

How To Test Your Pool Water For Iron

Usually, the same strips or kit that test for copper will also test for iron. It just makes sense as both are metal elements.

The only difference will be that once youve filled the test tube with a sample of your pool water, youll add a special solution made to test for iron. Then compare the water color to the color coded chart included with the kit.

Types Of Pool Testing Kits

How To Test Your Pool pH

There are 3 types of pool water testing kits: The liquid testing kit, test strip, and digital test kit. Each of these kits should effectively check for different pool chemical levels, including pH, alkalinity, Calcium hardness, Bromine, Calcium hypochlorite, Chlorine levels, Cyanuric acid, and Sodium bicarbonate.

The liquid pool test kit

This type makes use of liquid reagents that come in dropper bottles, and require you to scoop some water samples from the pool and drop some reagents into the water. It is quick and easy to do with fairly accurate results.

Test strips

It involves dipping the test strip directly into the swimming pool water and checking the colors on the strip to determine the chemical levels. Although test strips are super easy to use, their results are sometimes inaccurate.

Digital test kits

The digital pool tester is an electronic device that also uses reagents but with the electronic device doing all the readings and displaying the chemical levels for you to read. Considering test accuracy, digital pool testers have accurate readings but are much more expensive than the others and require periodic calibration.

What Do I Test The Pool Water For

As a pool owner, youll keep track of 5 main areas:

  • pH

pH is how we measure how acidic or basic/alkaline the pool water is.

The scale ranges from 1 to 14 . Pure water is right in the middle, at 7.

Why is incorrect pH bad for your pool?

Whether too high or too low, improper pH levels can damage your pool and its equipment.

The Importance Of Regular Pool Maintenance

Just like with your home, regular maintenance is an important part of preventing damage to your pool. Proactive maintenance can help extend your pool liner and pool equipments longevity to help you and your family enjoy your backyard pool for longer. Your regular maintenance routine should include cleaning, water quality testing, and equipment testing. To purchase pool supplies in Toronto, find local pool companies like Seaway Pools & Hot Tubs.

Why Testing Your Pool Water Is Essential

If you have a pool, it is essential to test the water and sanitize it regularly. If chlorine levels are not maintained properly, bacteria and algae can grow inside the pool, causing health problems for swimmers who come into contact with it. Chloramines cause odors and also cause skin irritations such as dermatitis or eczema.

Without regularly testing your pool water, you may not realize that something is wrong until serious problems arise. Test kit results are much more reliable than just guessing when to add chemicals based on appearance alone. It also ensures that swimmers in your pool dont come into contact with dangerous bacteria or viruses.

Testing For Copper: Getting Rid Of The Green

Testing Your Pool Water

If your pool water is cloudy, or you have greenish or black stains on your liner, copper is a prime suspect. Copper buildup usually happens for one of two main reasons.

First, the tap water you use to fill your pool may contain trace amounts of copper. As water evaporates from your pool, it leaves the copper behind. The less water in the pool, the higher the copper levels.

To counter evaporation, youll add more water, which means you add more copper, and then more water evaporates, and that leavesyou guessed itmore copper in your pool.

Second, low pH levels can cause copper elements in your pool filter or plumbing to corrode. The corrosion will then make its way into your pool water. The longer the corrosion is left unaddressed, the more copper buildup youll have in your water.

Greenish stains on the pool walls and floors may be an indication of too much copper in your pool water.

How To Shock A Swimming Pool

Do you want to know how to shock a swimming pool? well..

If your pool water is starting to look cloudy or unsanitary rather than crystal clear, it may be time to shock your pool.;

Pool shocking is essential to keep your water free from chloramines and reduce algae growth. Every pool owner understands the importance of preventing algae and keeping the water healthy to swim in. It not only causes your pool to look unpleasant and unwelcoming, but it can produce an odour and create a slippery surface.;

;The purpose of pool shocking is to raise the chlorine level to breakpoint chlorination and remove all the chloramines. So, essentially there is little to no bacteria in the pool and the pool or spa is safe to swim in.

What Order Do You Balance Chemicals In

The order you balance your chemicals in is just as important as the quantities you use. For safe and accurate results, you should always test in the following order:

  • Start by testing alkalinity and making adjustments as needed
  • Next, test and adjust pH levels as needed
  • Third, test and adjust calcium hardness as needed
  • After taking these three steps, you can add sanitizer, test CYA levels, measure TDS levels, and shock the pool, as described above.

    How Often Should You Test Your Water

    Pool water testing is important in order to achieve and maintain a sanitary and well-functioning pool. The timespan for testing your pool water depends on how heavily or how lightly your pool is being used along with the daily air and water temperature. It also depends on the specific test being done. As a pool owner, you should be testing for:

    • Chlorine
    • ;Chlorine sanitizes your pool water and should be checked between 2 to 3 times a week. Free chlorine is the most important test as this tells you available chlorine for sanitizing
  • pH
  • Check your pH just as frequent as you check your chlorine balance, 2 to 3 times a week. By keeping your pH balanced your chlorine will stay at its highest level of effectiveness
  • Total Alkalinity
  • This should be tested once a week as the stability of this test influences the stability of your pH levels
  • Calcium Hardness
  • Calcium harness should be tested once a month. ;This tends to fluctuate due to local water and chemicals added to your pool.
  • Total Dissolved Solids
  • If this level is too high, it can disturb the efficiency of your pool chemicals. This is why these levels should be checked on a monthly basis as well.
  • Metals
  • How Often To Test For Copper

    What should I use to test my pool water?

    While its ideal to conduct pool water testing for chlorine and pH levels weekly, its sufficient to test for copper once a month. Testing your water on a regular basis will keep copper levels at bay before you even see its effects. This will mean less work for you as you wont have to remove liner stains on top of addressing the copper in your water.

    In addition, because low pH levels can contribute to high copper levels, its essential to test them weekly. Keep them under control, and you may be able to avoid copper buildup altogether.

    Signs You Have A Leak In Your Plumbing System Include

    • Low Water Pressure The more air in your lines, the less room there is for water. Be sure to check your filters pressure gauge and if the PSI rating is lower than your normal reading, use the filters air relief to release air pressure.
    • Unable to Prime If your pump suddenly is unable to be primed, it could be as simple as a closed valve or a blocked impeller. Be sure to check a few other things to really single out this issue.
    • Losing Prime If the pump runs dry after manually priming the pump with a hose, it could be a sign of a more severe air leak.
    • Air Bubbles The most common sign you have air in your lines, air bubbles throughout your pool during the runtime of the pump shows an issue that needs further diving into.

    How Do I Test Pool Water

    There are several types of testing supplies available on the market varying in price and accuracy.;Since I work for a company that sells pool supplies, it was fairly easy for me to get customer input via our amazing review program, and I was able to narrow down the bestselling water testing supplies to make it easier for you to make the selection to your liking.

    Time Between Sample And Result

    One of the biggest reasons for inaccurate water testing results, besides where you take the water sample from, is time. Leaving your water sample exposed for too long before testing it can lead to inaccurate results.

    Similarly, when using a solution-based test, leaving the final solution for too long can lead to changes in the colour, giving inaccurate readings. Thankfully, simply performing the test as instructed without unintended breaks will remove this issue.

    Is Your Cya Too High

    How To Test Your Pool 4

    Also known as stabilizer or conditioner, CYA binds to the chlorine to keep it from evaporating. Youll find it in trichlor or dichlor tabs, and any kind of stabilized chlorine on the market for your pool. Its also sold separately as a stand-alone product that you can add yourself.

    Just because CYA is in lots of pools doesnt mean all pool owners understand it, though.

    Adding more stabilized chlorine means adding more CYA. Over time, this can lead to a problematic buildup. Experts recommend between 30 and 50 ppm CYA for the right balance, and regulation requires less than 100 ppm CYA. But what happens when your pools levels rise above this?

    The chlorine cant do its job its bound to the CYA, instead of being free and available to sanitize and oxidize. That makes for a germy pool. It can also mean algae growth. The only way to know if you have too much CYA is to test for it.

    Electronic Tester To Test Swimming Pool Ph

    Another way to test swimming pool pH is by the use of an electronic tester. Compared to test strips, electronic pH testers have three advantages. First, electronic pH testers will give you an exact number. This is an advantage over strip testing, because with strip tests, youll have to guess what your pools pH is based on the color of a strip. Electronic pH testers, however, will give you an exact read out of your pools pH so theres no guess work involved.

    Second, electronic pH testers will save you money in the long run. While electronic testers can cost up to $100 dollars or more, theres no need to refill them. Theyre a one-time purchase! The last advantage of an electronic tester is related to the second advantage. With an electronic tester, youll never find yourself without a way to test your pools pH. That means youll never be caught off-guard again! If the investment of an electronic pH tester seems appealing to you, it should definitely be the go-to option because of its many advantages.

    What Chemicals Do You Need For A Pool

    Certain items on the list below are essential to keep on hand, such as pool shock chemicals, which are used to sanitize contaminated water. Others, such as stain removers, may not be necessary for every pool owner. You should consult with a pool care and maintenance expert, like the pool service technicians at Latham Pool Products, to determine which chemical products are right for your swimming pool needs. With that in mind, here are a few common pool chemicals you might want to learn about:
