Customer Questions & Answers

  • Question: What is Calcium Hardness Increaser, and why is it important for pools?

    Answer: Calcium Hardness Increaser is a granular product used to raise the calcium hardness levels in swimming pools and spas. It is crucial for preventing corrosion of pool surfaces and equipment, as low calcium levels can lead to problems like etching and pit marks. By maintaining proper calcium hardness levels, you also help stabilize pH levels and reduce water balance issues, contributing to a more enjoyable swimming environment.
  • Question: How do I use Calcium Hardness Increaser in my pool?

    Answer: To use Calcium Hardness Increaser, first, test your pool water to determine the current calcium hardness level. Then, according to package instructions, broadcast the granular product evenly across the pool surface. Circulate the water for several hours to allow the product to dissolve and mix thoroughly. Consistent testing after application will help you maintain optimal hardness levels.
  • Question: Can Calcium Hardness Increaser be used in hot tubs as well?

    Answer: Yes, Calcium Hardness Increaser is suitable for both pools and hot tubs. Maintaining appropriate calcium levels is essential for hot tubs in particular, as they experience higher temperatures and can be more prone to scale buildup or corrosion when calcium levels are too low. Adding this product can help keep the water safe and comfortable for soaking.
  • Question: What symptoms indicate that I need more calcium hardness in my pool?

    Answer: Signs that you need to increase calcium hardness include etching on plaster surfaces, metallic stains, and frequent pH fluctuations. If you notice cloudiness in your water or scaling on tiles, it might also indicate low calcium levels. Regular testing will help you proactively maintain water balance and prevent damage to your pool equipment and surfaces.
  • Question: Is Calcium Hardness Increaser safe for swimmers?

    Answer: Calcium Hardness Increaser is safe for swimmers when used as directed. The product helps create balanced water chemistry, which is essential for safe swimming. However, allow adequate circulation time after adding before swimming to ensure uniform distribution in the water, maintaining comfort and minimizing any temporary cloudiness.
  • Question: What water testing is necessary to determine calcium levels?

    Answer: To determine calcium hardness levels in your pool, use a reliable water testing kit or strips. Test the water for total hardness, with ideal levels generally ranging between 200-400 ppm (parts per million). Testing should be done regularly, especially after heavy rainfall or pool usage, to ensure proper calcium levels are maintained.
  • Question: Can I use other chemicals along with Calcium Hardness Increaser?

    Answer: Yes, you can use other pool chemicals along with Calcium Hardness Increaser. However, it is important to ensure proper timing when applying them. For instance, adjust pH and alkalinity levels before adding calcium increaser. Consult the product guidelines for specific recommendations since combining certain chemicals may require a waiting period to ensure safety and effectiveness.
  • Question: What happens if I add too much Calcium Hardness Increaser?

    Answer: Adding too much Calcium Hardness Increaser can lead to excessively high calcium levels, which can result in scaling on surfaces, cloudy water, and difficulty maintaining balanced water chemistry. If this occurs, you may need to partially drain and refill your pool with fresh water to dilute the calcium concentration back to advisable levels.
  • Question: How often should I add Calcium Hardness Increaser to my pool?

    Answer: The frequency of adding Calcium Hardness Increaser depends on your pool's usage, environmental factors, and water evaporation rates. Regular water tests will guide your decisions. Typically, adding it on a monthly basis or after heavy usage is sufficient to maintain the desired calcium hardness levels, ensuring a healthy swimming pool environment.
  • Question: Where can I buy Calcium Hardness Increaser, Granular, Pack of 2?

    Answer: You can conveniently purchase Calcium Hardness Increaser, Granular, Pack of 2 on Ubuy. They offer a range of products for pool maintenance, ensuring quality and availability. Simply visit their website and search for the product to find your needed supplies.
