I just bought a 4 year old Jacuzzi spa, and can't wait to use it. This is my 1st spa. I'm picking it up this week, but my site isn't quite ready, so I'll be storing it in my garage for a week or two. The spa has already been drained. I've been told that some nasty bacteria can develop if it sits long enough, because it's difficult to drain all the water (someone told me a friend and his wife got some sort of rash or skin condition from bacteria in water after storing theirs before set up) I can flush it in my garage into a floor drain. Are there any chemicals I should put in it while I store it? High dose of chlorine? Also since the spa is used, I'd like to sanitize it pretty thoroughly.
Thanks in advance for any info
