Hi there, I found your site searching for help with my spa. We recently purchased a Bull Frog Spa. We are very happy with it, however can't seem, even with help from the store, to get the chemicals right. We used Chlorine. I can get good PH, Alkalinity and Stabalizer numbers, but will have no chlorine, or chlorine, alkalinity and stabalizer are good, but low PH. Anyone else had this problem??
