An important part of hot tub maintenance is to ensure the water in it has the correct pH. It makes for a more pleasurable and therapeutic experience, as the water is healthier and more hygienic.
You can test the pH using test strips or tablets. If your pH level indicates a reading above 7.6, it means the water is poorly sanitized. It leads to cloudy water and flaky scale building up on your spa surfaces, so you need to add a Spa pH Reducer that brings down the pH value to the accurate level.
On the other hand if the pH level has dropped below 7.2, it means the water in your hot tub is extremely acidic. Thus it becomes tougher for your sanitizer to work effectively, so people in the hot tub are exposed to potentially harmful contaminants, while metal parts and fittings get corroded. A Spa pH Increaser takes care of the problem!
