I was last year in Tijuana. There I learned to love spa and saltwater to relax. After the trip, I've decided to have salt water hot tub at home, so I could come home after a long and hard day and just laying there and relax in hot water. And it's easy to maintain it, like, I just replace cartridges every few months and clean the filter and that's it. I guess if I had a husband he would probably do all these things, but that's okay. Well, based on my experience I can say that a hot tub with salt water is the best way to calm down, relax and take some important decisions with a fresh mind.
