You should know that testing the pH in the jacuzzi is extremely important when it comes to professional hot tubs.
Check the pH level weekly. The pH can be affected by the number of users, the addition of water and other spa substances, as well as the type of disinfectant used.
Maintaining an appropriate pH level is important for:
– Optimizing the effects of disinfectants
- Keeping the water at a comfortable level
– Preventing equipment damage
Next, we present you the effects that an outside pH can have range 7.2-7.6 and instructions for adjusting its appropriate level.
If the pH level in the jacuzzi is too low:
• The disinfectant will dissipate quickly;
• Water can become irritating for users;
• Spa equipment can corrode.
If the pH level in the jacuzzi is too high:
• The disinfectant is no longer as effective;
• Deposits will form on the spa tub and equipment;
• The water is no longer clear;
• Can lead to filter blockage.
Because you understood from the above why it is important to test the pH level in the jacuzzi, we will present you the steps to follow so that this stage does not seem so difficult:
1. Testing the water
We recommend two testing methods which, from our point of view, are the most effective:
– Testing using a test kit with reagents. This is considered the optimal testing method;
– Test strips, the method most used by spa owners. Keep in mind that these strips are sensitive to heat and humidity, which can lead to incorrect readings, so store them according to the instructions.
The pH in the jacuzzi must be within the range 7.2-7.6.
2. Use only recommended substances.
If, after testing, you find that the pH in the jacuzzi is high, add sodium bisulfate (also known as acid sodium sulfate): pH minus. Otherwise, if the pH is low, add sodium bicarbonate to the spa water: pH plus.
3. Dilute the substances in water before adding them to the jacuzzi. With a bucket, take the water from the spa and add sodium bisulfate to lower the pH or sodium bicarbonate to increase the pH. Always respect the amounts recommended on the product label so that the pH in the jacuzzi can be adjusted properly.
4. Start the pumps (activate the self-cleaning cycle) when you add the substances to the jacuzzi. It is important not to use the spa when adjusting the pH.
5. Gradually add the diluted substances to the spa. Follow this step strictly so as not to damage the tub or the equipment in the jacuzzi.
6. After adding sodium bicarbonate or sodium bisulfate, wait 2 hours to test the spa water. Failure to observe this indication may lead to inconclusive measurements. If the pH adjustment in the jacuzzi has not been achieved even after the recommended time interval has passed, repeat the previously described steps and repeat the water testing.
7. Periodically empty the water from the jacuzzi. Once every 4 or 6 months you should do this. The need to change the spa water is all the more obvious the more difficult it will be to bring the pH level into the recommended range.
