Why is my pH so high in my spa?
Hot tubs in particular generate a lot of bubbles and tend to have higher temperatures. This combination creates a gas called carbon dioxide very quickly. Carbon dioxide builds up and makes the pH go up. This is why hot tub owners, on a regular basis, need to add something to lower their pH and alkalinity.
When should I check my hot tub chemicals?
To make sure the water stays sanitized and that alkalinity and pH are always in balance, perform hot tub water testing at least once a week. If your spa gets a lot of use, it’s been rained on, test it more often. And of course, test it whenever you add chemicals.
What is the correct pH of a hot tub?
between 7.2 and 7.8
The safe pH range for a hot tub is between 7.2 and 7.8—very slightly alkaline. At this pH, chlorine in the water will work effectively to keep the water clean, and, therefore, not harmful to you. Minerals in the water and sanitizers you add all affect the pH level; you should check it twice per week.
How do I adjust the pH in my hot tub?
To increase the pH levels in your hot tub, add a pH increaser to bring the levels back to normal. It’s important to monitor the total alkalinity levels as the pH increaser will raise the TA level. Keep retesting the water to ensure the water is balanced.
How to test chemicals for hot tub start up?
In this episode of Master Spas TV, Shane will provide step-by-step, hot tub start up chemical instructions including how to test hot tub water, what chemicals to add to the hot tub, and the importance of adding chemicals in a specific order.
Why is the pH of hot tub chlorine important?
Alkalinity is a measurement of how well your water neutralizes acid. The higher the alkalinity, the more acid it will take to lower your water’s pH. The pH of spa water is important because chlorine works best at eliminating bacteria at a certain pH level (more on this below).
Where can I buy chlorine test strips for my hot tub?
Once your spa is up and running, use test strips regularly to check your levels of alkalinity, pH, calcium or water hardness, and chlorine. Color-coded test strips can be purchased from your local hot tub dealer.
What to do if your spa water is high in calcium?
Using Spa Defender gives the best preventive maintenance against scale formation. Also, if your water is high in calcium this is where you may want to use water that is treated by a softener to fill your spa. In many cases you will find a low calcium reading that can be adjusted by using Calcium Booster .
What should the pH level in spa water be?
If your total alkalinity is too high, your pH level will be almost impossible to change. If your total alkalinity is too low, your pH will be very volatile. The total alkalinity should be between 60 and 120 PPM (PPM = parts per million). What is pH? pH indicates how acidic or alkaline your spa water is.

What do you need to know about spa chemistry?
This means balancing the chemical properties of our spa water so that it is neither too alkaline nor too acidic. It also means maintaining a sanitizing system to keep the water healthy and free of harmful microbes. After reading this section, go to Preparation & Maintenance for complete directions.
What happens when the alkalinity in a spa is low?
Low total Alkalinity can result in the following problems: Corrosion of metal parts (hearters, steps, other equipment) Etching of the plaster, marcite, marbelite, or grouting. Staining of the spa shell or pool surface. Rapid fluctuations in pH. Burning eyes/nose. Itchy skin. Green water.
