It‘s important to test the water in your pool on a regular basis to make sure the chemistry is balanced.
How often you need to test depends on a few factors, including how often the pool is used, what type of pool you have, and what type of filtration system you use.
If you have a residential pool that is used regularly, it‘s a good idea to test the water at least once a week. If the pool is used less often, you can test it every other week.
If you have a commercial pool or one with a lot of swimmers, you should test the water daily or even multiple times per day.
There are a few different ways to test pool water.
You can use test strips, which are dipped into the water and then compared to a chart to determine the chlorine, pH, and alkalinity levels.
Test kits that use liquid chemicals are also available. These kits give more accurate results but take longer to use.
