I was more than a little apprehensive about buying this for my hot tub. When i put one in my spa, the next day I almost fell over from the chlorine smell, but the water was chrystal clear. This is made for a 10,000 gal pool, so I knew I had to slow the interaction of water and pill, no problem !I ended up making a floater for it out of some high density shipping foam, I also had to put it in a plastic bag with two 1/4" holes in it so the water has a very slow flow thru the bag, which eliminated the chlorine odor completely. Its been a month and the pill is still 3" big. And my water is oderlessly crystal clear.
