Thank you again for the advice. I wasn't sure which cleaner to use, I will give the Spa System flush a try. Not sure if I am looking forward to seeing all the gunk or not. Sure will be nice to know that the tub is clean though, even in the pipes. Bill

Hillbilly Hot Tub, I think you have something here. I had wiped down the inside of the cover when I got it (only about a year old). There was black (mold, mildew) on it. I thought this would be enough. After educating myself better here, I decided to dig deaper. On Monday I took the cover off and took it into the garage where I could pull the foam. The plastic is in good shape. I wiped the plastic and also turned the cover inside out and cleaned with a heavy bleach solution (there was mold in the seams), rinsed and put back together. Put the cover back on and shocked the tub. Took a soak last night and I believe my musty smell is gone. Yea! I still want to superchlorinate and bioclean on my next water change for good measure if nothing else. Thank you, Bill

Jerimiah, Thanks for the reply. I am using a new filter and I am using Bromine. If I understand correctly, you are saying that I need to drain the tub before doing any sanitizing? Also I would superchlorinate before biocleaning, but I can do this in the same water? It may be incorrect, but I plan on using dichlor (or possibly even bleach -clorox) for my superchlorinating. What would it do to the tub if I superclorinate with the bromine currently in there? And then bioclean all with the water currently have in there? Thanks again, Bill

I am a first time spa owner and have a new-to-me sundance spa. Approx 400 gal. I am using bromine and following the 3 day system. I wanted to start with a clean tub and asked the local dealer what to do with a used tub. I was told to add about 4 gal of vinegar to the tub and run it for at least a day or longer maybe even a week, drain and I'm good. I'm pretty sure I wasted my time. I am learning about this and am fairly happy with my bromine, PH, and TA levels. And like I said, I am following the 3 day Leisure Time program. After soaking and dried off I can smell bromine and what seems like a musty smell on my skin. I expect the bromine, but musty no. I would like to do a deep cleaning and wondering what the best practice is. I would like to superchlorinate (to chemically cleanse) and bioclean (using Swirl Away, Spa Purge, or Spa Flush). Which should I do first and can I use the same water for both or should it be changed for each procedure? I would think that I should bioclean first and then superchlorinate. Thanks for the advice, Bill
