I've been using liquid chlorine in my tub very successfully since I purchased it. I have to say this tub is the best investment I've ever made. Every day that I come home from work, I get in it to help with the 45 years of aches and pains. There were only a handful of times that I did not use it during the winter months because it was so bitter cold outside. I absolutely love using it mostly in the colder months at 102°. I decided to turn the temp down to 95-97° for summer time use. I may turn it down a bit more when it gets really hot. I didn't use it as much my first summer. Needless to say, someone else loves it too! 
Im still so happy I did not put it down at the pool! LOL
