Decontaminating a hot tub or Spa is a 3-day process and it requires that you use granular chlorine to Super chlorinate the water. A chlorine level of 30 parts per million must be maintained for 72 hours for the decontamination to be effective.<\/p>\n<p>Step One, add granular chlorine at the ratio of 5 tablespoons per 100 gallons of spa water for this treatment to be effective it is crucial that the chlorine is distributed throughout the entire plumbing system. Ensure that diverter valves are set Midway and that all Jets valves, waterfalls, water features and aerators are open and are subjected to the chlorine. If your tub has a floor drain open the drain to ensure that some of the chlorinated water is bled through the drain at the onset of this procedure, this is very important to do because built-in drains are a dead end in the plumbing and the chlorine will not naturally make its way down to that part of the plumbing but the contaminants will. Be sure to leave your filters and headrests in and the lid closed. Do not use the spa during the decontamination process.<\/p>\n<p>Step Two, check the chlorine reading after 24, 48 and 72 hours. If at any time these intervals the chlorine level is below 30 parts per million, treat the water again with the same amount of chlorine as you previously did and restart the 72-hour clock. Ensure that you have achieved 72 continuous hours of successful chlorination before proceeding to the next step.<\/p>\n<p>Step Three, remove your filter and clean it. For detailed instructions on how to clean your hot tub filters you can view our video on filter cleaning or email us for detailed instructions at Solutions@spamarvel.com.<\/p>\n<p>Step Four, use a plumbing cleaner or a purge product such as Spa Marvel Cleanser and then drain the spa.<\/p>\n<p>Step Five, fill the spa and install the clean filter as per your spa manufacturer&#8217;s directions and carry on enjoying your hot tub the way it&#8217;s meant to be enjoyed.<\/p>\n<p>If you need further assistance with your spa decontamination or have any questions related to Spa water care contact us at solution@marvel.com and one of our water Care Professionals will work with you to ensure that you are enjoying your hot tub experience.<\/p>\n<p>Keep your spa environment pristine with Spa Marvel.
