Customer Questions & Answers

  • Question: What is HTH Spa 86135 Non Chlorine Shock Oxidizer used for?

    Answer: HTH Spa 86135 Non Chlorine Shock Oxidizer is specifically designed to clarify spa and hot tub water by effectively removing organic contaminants. This product works by oxidizing impurities such as oils, lotions, and bacteria, which can cause water to become cloudy. Regular use of this oxidizer helps maintain crystal-clear water, enhancing your enjoyment and providing a sanitary environment for soaking.
  • Question: How does non-chlorine shock differ from traditional chlorine shock?

    Answer: Non-chlorine shock, like HTH Spa 86135, utilizes potassium peroxymonosulfate to effectively oxidize contaminants without adding chlorine to the water. This is particularly beneficial for users who are sensitive to chlorine or seek to avoid strong chemical odors. Non-chlorine shock treats water quickly and allows for immediate use of the spa after application, making it a convenient choice for regular maintenance.
  • Question: How often should I use HTH Non Chlorine Shock in my hot tub?

    Answer: For optimal performance, it's recommended to use HTH Non Chlorine Shock at least once a week, particularly if the hot tub is used frequently. Additionally, upon heavy usage or after hosting guests, a post-use shock treatment can be beneficial. Regular use ensures clear water and helps prevent the buildup of contaminants, thus providing a consistently enjoyable spa experience.
  • Question: Can I use HTH Non Chlorine Shock with other spa chemicals?

    Answer: Yes, HTH Non Chlorine Shock is compatible with most other spa chemicals, including sanitizers like bromine or chlorine. However, it is crucial to follow the manufacturer's guidelines and ensure that the water's pH and alkalinity levels are balanced prior to application. Using in conjunction with other chemicals can enhance overall water quality and performance.
  • Question: Is HTH Spa 86135 Non Chlorine Shock safe for all types of spas?

    Answer: HTH Spa 86135 Non Chlorine Shock is safe for use in all types of spas and hot tubs, including inflatable and traditional models. Its pH-neutral formula minimizes potential negative effects on spa materials, making it suitable for regular use. However, always consult your spa's guidelines to confirm that the products you use are compatible.
  • Question: How do you apply HTH Non Chlorine Shock to your spa?

    Answer: To apply HTH Non Chlorine Shock, start by removing any debris from the water surface. Then, distribute the recommended amount evenly across the spa water while the pump is running to ensure proper mixing. This method helps enhance the oxidizing effect, providing a thorough treatment that clears cloudy water and elevates your spa experience.
  • Question: What should I do if the water remains cloudy after using HTH Non Chlorine Shock?

    Answer: If the water remains cloudy after treatment, it could be due to a high level of debris or imbalanced water chemistry. First, check and adjust the pH and alkalinity levels. Additionally, ensure proper filtration by cleaning or replacing your filter if necessary. Sometimes, combining this oxidizer with flocculants can help clear stubborn cloudiness.
  • Question: Can I use HTH Spa 86135 Non Chlorine Shock for outdoor spas?

    Answer: Certainly! HTH Spa 86135 Non Chlorine Shock is ideal for outdoor spas as it effectively deals with contaminants often found in outdoor settings, such as leaves and pollen. Regular use ensures that outdoor spas maintain clarity and cleanliness, promoting a safe and pleasant soaking environment for you and your guests.
  • Question: Will HTH Non Chlorine Shock affect the spa's chemical balance?

    Answer: HTH Non Chlorine Shock is formulated to be pH-neutral, meaning it minimizes disruption to the overall chemical balance of the spa. However, it’s important to monitor the water chemistry regularly. Regular use will facilitate clearer water without significantly altering the chemical levels, ensuring a pleasant soaking experience.
  • Question: Where can I buy HTH Spa 86135 Non Chlorine Shock Oxidizer?

    Answer: You can purchase HTH Spa 86135 Non Chlorine Shock Oxidizer at Ubuy, which offers a convenient shopping experience for spa and hot tub chemicals. Ubuy not only provides a variety of options tailored to your needs but also ensures that you have access to reliable products for maintaining your spa's water clarity.
