Ok so I guess it would not hurt to use it wouldn't cause a gaseous affect. I think I may use it once and see how it works. I'll probably just stick to chlorine. So confusing all the di-chlor, tri- chlor and all the rest. Chlorine is the only thing that isn't too confusing. I was going to get a floater so when I go away for a week or two the floater could watch the pool until I get back. Honestly don't know a thing about floaters and since I have a fiberglass pool I already read to keep it tied off so it doesn't touch the side. I was thinking or two lines one line going from my ladder and the other to the skimmer lid on the deck that way it would be in the middle and couldn't move too far. Thank you for answering and thanks to watermom for setting up this conversation again thanks to you both
