I have the Techniclor and love it. It has made my Spa much easier to maintain, and I never worry about zero chlorine. I recently was gone for 10 days, came back to 4 PPM. Now that I have it, I will never be without it. And no, I have no interest in Technichor at all. I have 30 PPM CYA, 30 PPM Borates, Alkalinity at 50, PH at 7.4, and I basically add a ounce of Clorox after each soak.... If I don't use it, I don't touch it....Period. It maintains 2-4 PPM if I don't. EASY. I love it.
