Just got a new to me hot tub delivered today. I got it from a buddy of mine. He drained it about a year ago, because he and his wife purchased a lake house a couple years ago. They just never had time to use it anymore, so he said if I wanted it I could have it. all I had to do was pay to have it moved. He said everything was working perfectly when he drained it. So now I have it, and I have never had a hot tub. I did read enough to know to purchase some Ahh-Some cleaner from Amazon. The Tub should be wired in the next couple of days. Should I go ahead and fill it prior to it being wired? What is the best process for cleaning a tub that has not been used in over a year? Thanks in advance for the help. You guys were a life saver after I bought this house last year with an in ground pool. Your help, and the education i got here was priceless. My pool ended up being easy to take care of after following the directions I received here. I even went from using liquid Chlorine to installing a SWG myself, but that is a whole different story. Now I need advice on how to get this thing going. Its an older Leisure Bay Spa. I have attached a few pics.
