Swimming pool and SPA testers: A must have!
27.01.2022

Water testing is essential to keep your pool or spa water from becoming hazardous. Swimming pool chlorine can become harmful to the skin, eyes, and internal organs if it is ingested by swimmers in the water if the right chemical levels are not carefully maintained.

What is the recommended frequency for conducting pool and spa water tests? How often?

To ensure the health and safety of swimmers of your pool and spa facilities, it must undergo routine testing.

To successfully monitor pH levels and disinfection residuals like chlorine and reduce swimmer sensitivity to chemicals, daily pool water testing is required. Weekly testing must be conducted to check for elements including alkalinity, total dissolved solids, calcium hardness, and water balance in order to maintain water quality.

Additionally, water testing is critical for safeguarding your pool's framework. Your treatment plan can be optimized by having effective water management, which also helps to keep disinfection under control and preserve water balance.

Fortunately, there are a lot of water testers in the market nowadays, which are convenient and reasonably priced.

It can be as simple as the traditional test tube kit that includes an eyedropper, litmus paper, and a few chemicals. Those can do a good job of measuring pH, determining chlorine concentration, and so forth. In many testing kits, you can also measure cyanuric acid, urine and ammonia products, as well as calcium, to determine the hardness of water.

That being said, let's find out which water testing kit is best and accurate!

Test Strips

The strips change color when certain compounds are present, and you can then compare the strip to a chart to determine the concentration of the particular chemical. These tests are frequently used to calculate the pH or quantity of chlorine in the water.

The Total Alkalinity (TA) and pH levels of your swimming pool or spa are measured by even the simplest pool and hot tub test strips. Others, including those that monitor cyanuric acid and nitrite, can measure up to seven elements. Which type of sanitizer a test strip measures—chlorine, bromine, or both—is a crucial distinction to watch out for.

Though they are the cheapest, simplest and quickest way to test your spa/pool water, strips are the least accurate method.

Reagent Test Kits

Reagents are substances that can be identified in test kits used to examine the chemical composition and water balance of your spa or swimming pool water. They are intended to cause a chemical reaction that will reveal these components' concentrations.

It is said to be the next most precise technique for testing your water. There are two different testing procedures for chlorine: OTO and DPD. OTO is the test result in the yellow color. You cannot calculate the level of Combined Chlorine in your pool because it only calculates Free Available Chlorine and does not test for Total Chlorine. DPD is more exact.

Reagents are used in test kits, which you systematically add to your water sample. Since pH and chlorine tests are comparison tests, we must rely on the tester's vision to establish a precise color analysis. Tests for total alkalinity, calcium hardness, and cyanuric acid (a stabilizer) are "Titration Tests," meaning that we count the drops put up until a color change is seen. The reading in ppm (parts per million) is then calculated by multiplying the total number of drops by a specific amount, typically 10.

Digital Test Kits

They are excellent for anyone who struggles to read colors because they are quick and precise. They are more expensive than other test kits, however, they offer the ultimate accuracy and the testing method chosen by most spa/pool owner. Some digital test kits do away with the need to use look-up tables or visually assess minute color variations.

The user is given the following steps, or what to add to the spa water, via an internal photometer after it has measured the sample. An internal photometer evaluates the extract and tells the user what to add to the spa water in the next phases.

Final Thoughts

Even the smallest pool or spa needs to be maintained. There is no easier way for pool owners to determine whether their water haven has the right pH value and chlorine content than with the help of the pool and spa testers.

It is vital to be mindful of how often your swimming pool and spa is used so you can organize your cleaning routine appropriately.

Test strips are typically the cheapest and simplest way to test water. Nevertheless, they screen for fewer substances than liquid test kits, although being generally quite accurate. Compared to test strips, liquid test kits cost more. However, your results will be quite accurate when utilized properly, which means adding the proper quantity of each reagent to your vial of pool water.

Select the best water testing kit according to your circumstances.

Always use fresh reagents; the majority have a shelf life of around a year. When it comes to swimming pool maintenance, make sure you don't let guesswork get in the way. Utilize current chemical and technological innovation to take control of your pool's fate and protect the wellbeing of your family.
