In this blog post on how to increase water hardness in hot tub, we’ll discuss a variety of options available so that you can get your hot tub back up and running swiftly! Keep reading for tips on how to raise the hardiness of your spa safely and effectively.
Needed Materials
Given below are the necessary materials that you need to have before increasing the water hardness in your hot tub:
- Calcium Chloride
- Baking Soda
- Borax
- Ph Increaser (Soda Ash)
- Test Strips or Kit
10 Simple Step-by-step Guidelines on How to Increase Water Hardness in Hot Tub:
Step 1: Test the Water
The first step in increasing water hardness is to test the current levels using a test strip or kit. This will give you an idea of how much hardness needs to be added to achieve the ideal level. It is recommended to keep the water hardness level between 150-250 ppm (parts per million). You can also consult your hot tub manufacturer for specific hardness level recommendations. But generally, the optimal level falls between 200-400 ppm.
Step 2: Use Calcium Chloride
Calcium chloride is a popular and effective way to increase water hardness in hot tubs. It is available in granular form and can be easily dissolved in warm water before adding it to your spa. When using calcium chloride, make sure to follow the manufacturer’s instructions for the correct dosage. You can also use a test strip to check the hardness level and add more if needed.
Step 3: Add Baking Soda
Another easy way to increase water hardness in your hot tub is by adding baking soda. It contains sodium bicarbonate, which helps raise both total alkalinity and pH levels in the water. Start by adding half a cup of baking soda and then test the water to see if the hardness level has increased. You may need to add more baking soda depending on your hot tub’s size and the current hardness levels.
Step 4: Use Borax
Bora is a slightly controversial method for increasing water hardness in hot tubs. Some experts recommend it, while others do not due to its potential to cause cloudiness in the water. However, if used correctly and in moderation, borax can be an effective way to increase water hardness. Follow the manufacturer’s instructions carefully and make sure to test the water after adding borax. It is also recommended to wait for 24 hours before using the hot tub.
Step 5: Check Alkalinity Levels
Before adding any chemicals, it is essential to check the total alkalinity levels in your hot tub. If the alkalinity level is low, it can affect water hardness and pH levels. Use a pH increaser or soda ash to raise alkalinity levels before proceeding with increasing water hardness. But make sure not to add too much as it can cause cloudy water. It is recommended to add small amounts and then test the water before adding more.
Step 6: Use Hot Tub Water Balance Products
Some hot tub water balance products are specifically designed to increase water hardness. These products contain a blend of essential minerals that can help raise the hardness level to the optimal range. Follow the manufacturer’s instructions carefully and test the water after adding any product. You can also consult with a hot tub professional for recommendations on the best product to use.
Step 7: Use Liquid Hardness Increaser
Another easy way to increase water hardness in your hot tub is by using a liquid hardness increaser. These products are readily available at most hot tub supply stores and can be easily added to your spa. Make sure to read the instructions and use a test strip to check the hardness levels before and after adding the product.
Step 8: Do Not Use Too Much
It is essential to maintain a balance when increasing water hardness in your hot tub. Adding too many chemicals or using too much of a specific product can lead to adverse effects such as cloudy water or skin irritation. Use small amounts, test the water regularly, and consult with a hot tub professional if needed. You can also refer to the manufacturer’s instructions for specific dosage recommendations.
Step 9: Wait for 24 Hours
After adding any chemicals or products to increase water hardness, it is essential to wait at least 24 hours before using your hot tub. This will allow the chemicals to circulate and stabilize in the water, ensuring safe use for bathers. You can also test the water again after 24 hours to make sure the hardness level is at an optimal range. But generally, it is recommended to wait for at least a day before using the hot tub.
Step 10: Regular Maintenance
Increasing water hardness in your hot tub is not a one-time process. It is essential to regularly test and maintain the hardness level to ensure a safe and comfortable bathing experience. Use test strips or kits regularly, follow the manufacturer’s instructions when adding chemicals, and consult with a professional if needed. With proper maintenance, you can keep your hot tub’s water hardness at an optimal range for an enjoyable soaking session every time.
Following these simple and easy steps on how to increase water hardness in hot tub, you can effectively increase water hardness in your hot tub. Remember to always prioritize safety and consult with a professional if needed. So go ahead, get your spa back up and running, and enjoy a relaxing soak in perfectly balanced water! Happy soaking!
Additional Tips on Maintaining Water Hardness
- Keep the Hot Tub Covered When Not in Use to Prevent Evaporation and Maintain Water Hardness Levels.
- Regularly Clean and Replace Filters to Ensure Proper Circulation of Chemicals and Minerals.
- Avoid Using Soft Water, as It Has a Low Mineral Content and Can Cause Corrosion in the Hot Tub’s Plumbing System.
- Consider Investing in a Mineral Cartridge That Can Help Maintain Water Hardness Levels in Between Chemical Treatments.
- Always Test the Water Before Using the Hot Tub to Ensure It is Safe and Comfortable for Bathers. Overall, Maintaining Proper Water Hardness Levels is Crucial for the Longevity of Your Hot Tub and a Pleasant Soaking Experience.
Do You Need to Use Professional Support?
If you are not comfortable with adding chemicals or maintaining your hot tub’s water hardness level, it is always best to seek professional support. A hot tub expert can assist you in testing and maintaining the optimal hardness level for your spa. They can also recommend specific products or give advice on how to increase water hardness safely and efficiently.
So do not hesitate to reach out for help if needed. Remember, keeping your hot tub’s water balanced is essential for a clean and enjoyable soaking experience. So take care of your hot tub, and it will take care of you!
Frequently Asked Questions
Q1: How Often Should I Test the Water Hardness in My Hot Tub?
