How To Properly Balance the pH Level in Your Hot Tub

check pH balance weekly
Why should you know how to properly balance the pH level in your hot tub? It turns out that an improper pH balance in your hot tub water can lead to issues that could cause skin and eye irritation to bathers or even make them ill.  An imbalance in the pH can also cause scale and corrosion of your spa equipment. How do you tell if your pH level is off? More importantly, how do you correct it?

What’s pH Anyway?

Determining the pH level of your hot tub water tells you how acidic or basic your water is. pH levels range from 0 to 14, with 7.4-7.6 being ideal for a hot tub. If the level is too low (acidic), your sanitizer will not work effectively, and your water could develop bacteria. Too high a pH level (basic) and your sanitizer will also not work well. Plus, your spa could develop scale and cloudy water. 

How to Measure pH

To get an accurate pH reading, use test strips or a liquid test kit. Get in the habit of testing your spa water weekly, at a minimum. Your test results will also tell you what the “Total Alkalinity” of your water is. 

Why Total Alkalinity is Important

To get to the perfect pH level, you need to first start with a check of your water’s total alkalinity and make any necessary adjustments. Total alkalinity is a buffer to pH, keeping it stable. The ideal range of total alkalinity is 80-120 ppm. Your total alkalinity must be in the proper range before you attempt to adjust the pH. Getting your total alkalinity in balance may be enough to fix your pH issues. 

How to Adjust Chemical Levels in Your Hot Tub

If the total alkalinity is too low, you can raise it with an alkalinity increaser product. If your pH level is too high, your alkalinity will be high also. Both can be lowered with a pH decreaser product. It is essential to pay attention to the dosage directions on the package of your products. Only once your total alkalinity is balanced should you move on to adjusting the pH.
