How Does Hard Water Affect My Hot Tub?

hard water in the hot tub

The perfect way to spend fall and winter evenings is relaxing in your very own hot tub. As you spend time in your hot tub, you will start to notice things about the hot tub itself as well as about the water you are enjoying. Pennsylvania is known for its hard water, and spa water is not an exception to the rule. This fact might bring up the question: “How does hard water affect my hot tub?” 

Goodall Pools & Spas can help you with the answer to this question.

Affected Water

Inviting hot tub water is clear and clean. The first thing that could indicate that hard water is affecting your hot tub is if the water is cloudy. Our high-quality products are here to help clear up this problem. We carry SpaGuard® chemicals that will keep your spa water healthy and ready for enjoyment. 

Calcium and other similar minerals are what make water hard. If the spa water becomes oversaturated with these substances, they don’t always get a chance to dissolve in the hot water. The minerals then drop out of the solution, leaving behind rough deposits of scale.

SpaGuard® Stain & Scale Control is a great preventative for keeping unwanted contaminants from building up. It is easy to add this to your weekly chemical maintenance list. If you are already seeing scale deposits, Off the Wall® Surface Cleaner is a good product to use with a brush on any surfaces of the hot tub that need attention. This helpful information directly from SpaGuard® talks about how to troubleshoot scale issues.

Unbalanced Water

Hard water can alter the chemistry of the hot tub water as well. Regular water tests will help you check the calcium hardness level. If the calcium is over 300 ppm, problems can occur. The chemistry can change quickly, which is why you want to do frequent tests to keep the spa water safe.

Damaged Hot Tub

Hard water that is left unattended will leave scale deposits on your hot tub. It can start settling in places that you will not see, such as deeper jets or heating elements. The hot tub and its equipment can be damaged if this issue does not get resolved. You also might start to see the effects of hard water around the waterline of the hot tub as stains appear.

Experienced Help

How does hard water affect my hot tub? Now you know the answers. The water can be affected and then become unsafe. The spa can also be damaged if the issue is not resolved.

Our Prestige Spa Maintenance teams service spas all across central Pennsylvania. We are happy to help you care for your spa if you don’t have time to troubleshoot issues like this. Let us prepare your spa for you and keep it running smoothly for your ultimate enjoyment.
