How To Test The Water In Your Inflatable Hot Tub

how-to-test-the-water-in-your-inflatable-hot-tub-ph-stripsAs we saw in our article How To Keep The Water Clean In Your Inflatable Hot Tub, it is important to check the quality of the water in your inflatable hot tub once a week.

This is to ensure that the chemicals you must add, to prevent the water harboring bacteria and algae, are at the correct levels.  It also means you can rest assured that your inflatable hot tub is safe and hygienic for you and your family to use. Plus, it keeps the hot tub clean and helps prolong its life.

The chemistry of testing the water can seem a little confusing if you are new to the world of portable hot tubs, so we will try to make it as simple as possible.

Basically, you need to test the pH level of the water in your inflatable hot tub. If this is fine, then no problem. Your hot tub is ready to use.

If the pH level is too low or too high, however, you will need to alter it.

Let’s look at the process you’ll need to follow, from the beginning.

Testing The pH Of The Water

how-to-test-the-water-in-your-inflatable-hot-tub-ta-stripsThe pH level of your water is a measure of how acidic or alkaline the water is in your hot tub.

If the pH balance is too low, the water will be acidic and you might experience some discomfort, such as itchy skin and stinging eyes. If the pH of the water is too high, then the water is too akaline. This will allow scale to build up on the surfaces of the hot tub, and in the water filter and massage jets.

In order to test the water, use hot tub pH test strips, which are easily available on sites such as Amazon.

Dip one of the strips in the water, hold it there for a few seconds, and remove it.  Wait for 20 seconds, and it will change color according to the pH of the water. You then compare the strip to the scale on the back of the container your pH strips come in.

The pH level of your water should ideally be between 7.4 and 7.6. However, the acceptable and safe range is between 7.2 and 7.8. If it is not within this range, you will need to adjust it.

Before you do that, however, you need to check the Total Alkalinity of the water.

Testing The Total Alkalinity Of The Water

The key to altering the pH level of your inflatable hot tub water lies in what is called the Total Alkalinity (TA) of the water.

You don’t need to go into the chemistry of Total Alkalinity, other than to know that it allows you to control the pH level of your hot tub water. So without getting the Total Alkalinity level right to start with, you won’t be able to get the pH level right.

Therefore, you need to test the Total Alkalinity level of your inflatable hot tub water, using TA test strips. Again, these are available from Amazon and other online stores.

Ideally, the TA of your hot tub water should be between 80 and 120 parts per million (ppm).

If it is within this range, you can then adjust the pH level as required, If the TA is outside of this range, though, you will need to alter the TA level before you work on the pH level.

It can seem confusing to owners of inflatable hot tubs exactly how to balance these levels. That’s because there can be a number of scenarios. So here is everything you need to know in its simplest form.

Don’t Worry

While all of this may sound difficult, you’ll quickly find that it is easier than you think.

The key is to carry out regular pH level checks, and keep your pH and TA levels at acceptable levels. Just a few minutes once a week doing this, and you and your family will have hours of fun enjoying the clean, safe, sparkly waters of your inflatable hot tub.

Remember: you should be spending more time enjoying your inflatable hot tub than working on it.
