What to consider when choosing hot tub test strips

A regular check on the water with a test strip will ensure the safety of you and your family members when using the hot tub. Here is a quick guide to help you choose a proper test strip kit for your equipment.

1. Material

The first impression of many people about the hot tub test strips is that they are very fragile. As a result, they think these test strips fail quickly and can only be used for only one time.

Hot tub test strips are designed to be used only once, however, they are made of quality materials that will be durable.

2. Multiple readings

Apart from the pH, you must also check the concentrations of many other elements in the water such as chlorine, total alkalinity, calcium hardness, or bromine. Hot tub test strips with multiple readings will allow you to check the concentrations of many substances at the same time.

There are many different types of swimming pool test strips on the market. But choosing a test strip with multiple readings will bring a lot of conveniences as you only need to try it once to check the density of all substances. Otherwise, you have to make multiple checks to test each type of chemical.

3. Fast reading

Fast reading is the deciding factor for the time that the hot tub test strips give the results. Typically, qualified test strips only take a few seconds to produce results after dipping into the water.

In today’s life, no one wants to wait too long for a simple task like checking the water of the hot tub. So, the faster hot tub test strips have results, the more they will be loved and selected by customers.

4. Value

Hot tub test strips are designed for single use only. As experts recommend that you should check the water in the hot tub regularly, a product that has a reasonable number of test strips is a wise choice.

You should choose products with at least 50 test strips in one box. With this quantity, you can use it for at least 1 month. This will save you money as well as time because you do not need to buy the same product many times.

5. Reading range

Hot tub test strips usually have a separate reading range. The reading range will let you know if there is any potential volatility in the water.

Reading ranges also tell you what level of chemicals safety indices in the water should be maintained.

Frequently Asked Questions

1. How often do you have to test the water in the hot tub?

Many people think that we should test the water in the hot tub every day. However, you can hardly maintain this because it will take you a lot of time.

The best way is to have hot tub test strips in the house so that you can check the water whenever needed.

2. Does the hot temperature affect the analyses?

Temperature affects both the volume and the speed of the reaction chemicals. So, the analysis may be not accurate under the impact of hot temperature.

Usually, a high temperature can make the result higher than usual.

3. How long do you immerse the check strips in the water?

Now, all hot tub test strips produce results within a short period. You only need to immerse the test strip in water for 15 to 20 seconds then it will change color and show results.

4. Are pool test strips accurate?

The accuracy of pool test strips is quite high. However, we cannot be sure that the results of pool test strips are always correct because some possible errors may occur whenever they can.

5. What will happen if I do not test my pool water?

If you do not test your hot tub water regularly, you cannot know what concentrations of chemicals in the water are. Also, you cannot know whether this level of chemicals is safe or not.

If there are not enough chemicals, algae and bacteria will easily grow and harm you. Conversely, immersion in water with high concentrations of chemicals can also cause skin diseases or other health problems.

6. Are all pool test strips the same?

Most types of hot tub test strips have the same basic features. However, each product will have its characteristics in terms of material, multiple readings, fast reading, value, and reading range.

This makes hot tub test strips diverse. You will have many choices. However, you should consider it more carefully to get the best choice.

7. Can you reuse spa test strips?

Most of the test strips are designed for only single use. So, you can not reuse them many times. Test strips usually include from 25 to 100 packs which you can use many times.

8. How to use hot tub test strips?

  • Run the pump in the pool for at least an hour before you start to test the concentration of chemicals in your pool water.
  • Soak the test strip in the water, then wait a while to see the results. Usually, it only takes 10 – 20 seconds for the test strip to change color.
  • Read the results by comparing the color on the test strip against the color chart on the bottle or the product’s packaging.

Storing the hot tub test strip after use carefully in a dry place for future use. You should also pay attention to the product’s expiry date. Expired test strips will not give accurate results.

9. What does free chlorine mean on the test strip?

If chlorine is not combined with chlorinated water, it is called “free chlorine”. Like combined chlorine, free chlorine is the chemical that helps to kill harmful microorganisms in water. This is the most important kind of chlorine because of its responsibility for cleaning your pool.

10. How do you put the right chemicals?

You can learn about the chemicals as well as how to treat them before you put them into the pool water.

Currently, there are many books, documents, and instructional videos on the Internet that you can refer to. You can also ask directly to the chemical sellers when buying them in the store.
