Customer Questions & Answers

Question:
What is the main purpose of Leisure Time CB-02 Calcium Booster?
Answer: The Leisure Time CB-02 Calcium Booster is designed to enhance the calcium levels in your spa and hot tub water. Proper calcium levels are crucial for preventing corrosion of metal components and reducing scale buildup in your system. By maintaining balanced water chemistry, you ensure a safer and more enjoyable soaking experience. This booster is particularly beneficial in areas with soft water, as it prevents damage to spa surfaces and equipment. -
Question:
How do I use the Calcium Booster in my hot tub?
Answer: To use Leisure Time CB-02 Calcium Booster, first ensure your hot tub water is balanced. Add the recommended amount of booster directly to your hot tub water while it is circulating. Allow it to mix thoroughly, which usually takes about 15 minutes. Regular testing of water chemistry is advised, especially after heavy usage, to ensure the calcium levels are optimal. This practice helps in maintaining overall spa health and user comfort. -
Question:
Is Leisure Time CB-02 safe for all types of hot tubs?
Answer: Yes, Leisure Time CB-02 Calcium Booster is safe for all types of hot tubs, including acrylic and fiberglass. Its formulation is designed to be gentle on surfaces while effectively boosting calcium levels. This makes it a versatile option for spa owners looking to maintain water quality without risking damage to their hot tubs. Just remember to follow the mixing instructions to ensure optimal results. -
Question:
How often should I add calcium booster to my spa?
Answer: The frequency of adding Leisure Time CB-02 Calcium Booster depends on your specific water chemistry and usage patterns. Typically, it is advisable to check calcium levels regularly, especially after refilling your hot tub. You may need to add the booster every few weeks or whenever your tests indicate low calcium. Keeping up with the maintenance schedule not only enhances water clarity and comfort but also prolongs the life of your spa's equipment. -
Question:
What are the symptoms of low calcium in hot tub water?
Answer: Symptoms of low calcium levels include itchy skin, cloudy water, and corrosion of metal fixtures. If you notice these issues, it’s essential to check your water chemistry. Low calcium can lead to damage to the spa's structural integrity and heating elements over time. By using Leisure Time Calcium Booster, you can help prevent these problems and ensure that your hot tub remains a relaxing retreat. -
Question:
Can I use this product if I have a saltwater hot tub?
Answer: Yes, Leisure Time CB-02 Calcium Booster can be used with saltwater hot tubs. While saltwater systems typically require different maintenance, maintaining proper calcium levels remains essential to prevent corrosion and scaling. Using this calcium booster will help ensure balanced water chemistry, contributing to the longevity of both your hot tub and its components. Always consult your hot tub manufacturer’s guidelines for specific recommendations. -
Question:
What should I do if I accidentally add too much calcium booster?
Answer: If you add too much Leisure Time CB-02 Calcium Booster, it’s essential to check your water chemistry immediately. Higher calcium levels can lead to scaling on surfaces and diminished water clarity. If excessive calcium is detected, you may need to drain some water and replace it with fresh water to dilute the levels. Regular testing will help maintain balance and ensure your hot tub remains enjoyable. -
Question:
Is there any special storage requirement for this product?
Answer: Leisure Time CB-02 Calcium Booster should be stored in a cool, dry place away from direct sunlight and extreme temperatures. Keeping the product sealed when not in use will help ensure its effectiveness and longevity. Proper storage protects the integrity of the chemicals, making it ready for use whenever you need to maintain your hot tub's water balance. -
Question:
How does Leisure Time CB-02 compare to other calcium boosters?
Answer: Leisure Time CB-02 stands out among calcium boosters due to its specialized formulation that ensures maximum effectiveness in maintaining proper calcium levels while being easy to use. Compared to other brands, CB-02 is recognized for its reliability and consistent performance, helping spa owners achieve clear and balanced water chemistry more effortlessly. Many users find that regular use of CB-02 simplifies their water maintenance routine. -

SpaChoice Chlorine 472-3-3061-02-K Editorial Review
The Leisure Time CB-04 Calcium Booster is a great product for spas and hot tubs. It is a 1-quart pack with 4 bottles, each being 32 ounces. The calcium booster helps increase the calcium hardness in your spa, and it is easy to use and apply. Leisure Time Calcium Booster contains 31-41% calcium chloride and other inert ingredients that make it effective in raising water hardness levels. Note that this product is only ideal for spas and hot tubs, and not pools. According to customer reviews, this product works much better than the granular version of calcium booster. It keeps filter cleaner than the granular type, and it works like a charm. Once it's within range, it stays in range. Customers also mentioned that it is more fiscally prudent and performs as advertised.
