It is the combined chlorine that creates the chlorine odours that are often associated with spas.<\/p>\n<p>Adding more free chlorine will break down the combined chlorine and become depleted. As such, it is difficult to maintain a respectable level of free chlorine when combined chlorine levels are high, allowing for decreased sanitizer efficacy.<\/p>\n<p>Without shocking the water to remove the combined chlorine, the sanitizing ability will continue to diminish, leading to unhealthy hot tub conditions.<\/p>\n<p>Hot tub shock also:<\/p>\n<ul>\n<li>Breaks down organic and inorganic waste in the water that can cause cloudy water and other problems<\/li>\n<li>Breaks the bonds that form in combined chlorine and combined bromine so that they can easily be removed from the water<\/li>\n<\/ul>\n<\/div>\n<h2 align=\"LEFT\"><span id=\"hsht-section-2\"><b>Different Hot Tub Shock Treatments<\/b><\/span><\/h2>\n<p>There are two main hot tub shock treatments: chlorine-based and non-chlorine shock.<span class=\"anchor\"  id=\"htcp-section-3\" style=\"font-family: Arial, serif;\"><\/span><\/p>\n<h4><span  id=\"hsht-section-3\"><strong>Chlorine-Based Shock<\/strong><\/span><span><strong><\/strong><\/span><\/h4>\n<p><a href=\"https:\/\/www.masterspas.com\/blog\/oxidizer-or-chlorine-for-hot-tub\/#:~:text=Dichlor%20for%20your%20spa,that%20it%20dissolves%20more%20quickly.\" target=\"_blank\" rel=\"noopener\"><strong>Dichlor shock<\/strong><\/a> (a type of chlorine called sodium dichloro-s-triazinetrione, often shortened to sodium dichlor or just dichlor) acts as a sanitizer and an oxidizer.

In addition, you should shock your hot tub whenever you refill the water to oxidize any combined chlorine and minerals<\/span><span style=\"color: #000000;\"><span lang=\"en-CA\"> in your tap water. <\/span><\/span><\/p>\n<p class=\"western\" lang=\"en-US\"><span lang=\"en-CA\">If your hot tub is used frequently, consider shocking it twice weekly.<\/span><\/p>\n<h2 align=\"LEFT\"><span  id=\"hsht-section-9\"><b>How Much Shock For Hot Tubs Should You Use?<\/b><\/span><\/h2>\n<p class=\"western\" lang=\"en-US\">If you\u2019re using chlorine or bromine as your shock treatment, you typically use 20 grams per 1,000 litres (4 teaspoons per 250 gallons) if the water is clear. If the water is cloudy, use 30 grams per 1,000 litres (6 teaspoons per 250 gallons if cloudy). Always follow the directions on the package to ensure proper dosage and application methods.<\/p>\n<p class=\"western\" lang=\"en-US\">For non-chlorine shock, apply the shock carefully according to the manufacturer\u2019s directions.<\/p>\n<p class=\"western\" lang=\"en-US\">You can choose a chlorine or non-chlorine-based shock treatment if you use a bromine sanitizer. However, never mix the dry chemicals, as this can create a dangerous chemical reaction.<\/p>\n<h2 align=\"LEFT\"><span  id=\"hsht-section-10\"><b>How To Shock A Hot Tub For The First Time<\/b><\/span><\/h2>\n<p class=\"western\" lang=\"en-US\">1. Remove your spa cover and leave it off for at least 20 minutes following the shock treatment.<br \/>2. Remove any accessories from the water.<br \/>3. Test your alkalinity and adjust if necessary. Ensure it\u2019s between 80-150, where 120-150 is ideal.<br \/>4. Test your pH and adjust if necessary. To maximize effectiveness, ensure it\u2019s between 7.2 to 7.8 unless you\u2019re using <strong><a href=\"https:\/\/spamarvel.com\/\" target=\"_blank\" rel=\"noopener\">Spa Marvel Water Treatment &amp; Conditioner<\/a><\/strong>, in which case the acceptable pH range is 7.2 to 8.2.<br \/>5. Turn off your blower and jets but leave your circulation pump operating.<br \/>6. Read the warning labels on the shock product packaging.<br \/>7. Measure your shock correctly following the directions on the package.<br \/>8. Carefully add your shock into your hot tub, following the instructions. Typically, you can add your shock product directly into the water. If any shock spills during treatment, clean it up promptly and dispose of it safely.<br \/>9. Wait 20-30 minutes following a shock treatment.<br \/>10. Retest your water. Once your sanitizer levels are back in acceptable ranges, it\u2019s safe to use your hot tub.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cShocking\u201d your hot tub is a term that describes adding a large quantity of an oxidizing agent to a hot tub or spa.
