If you plan to buy any of the aforementioned products, then ensure going through the instruction sheet and the user manual as they may fail at delivering accurate results if not used properly. The suggested lineup is honed by many and has enabled its audience to have a safer, fuss-free, and pleasant experience while making use of them at pools and spas. However, many of them from the list are self-diagnosing automated machines that make life easier. Yet, it is best suggested that you buy only the ones that fulfill your criterion and meet the requirements of pool water treatment, drinking water treatment, or checking salt content in it. Remember, the best is the one which is properly utilized.


Q.1) How Often Should I Test My Pool Water?

Ans. Commercial pools tend to test chlorine content every hour. For home pools, testing twice or thrice a week is more-than-enough. Owners must test for both acidity and chlorine content as these two factors depend on each other. Checking for calcium hardness and cyanuric acid can be done less frequently, as their levels don’t vary much.

Q.2) How Do I Maintain Balanced Chemical Levels?

Ans. First, you must check the acidity levels. This must be between 7.2 pH and 7.8 pH, ideally 7.6 pH. If your levels are beyond the limits, you can contact a swimming pool chemical dealer and add or remove the required chemicals. You can then add a certain amount of chlorine to maintain the desired level of residual chlorine, which is required to kill algae or germs.

Q.3) Can I Use Other Reagents for a Certain Tester?

Ans. In most cases, you cannot. The instruments only work with the reagents/strips that come in the package. Manufacturers generally produce the reagents in certain concentrations, and differing concentrations may be incompatible with your instrument. Your readings would be unreliable if used in such a manner.
