Hi Dave My dealer gave me two jars of a product from "hth spa" One reads "SHOCK" and its made up of Calcium Hypoclorite-47.6% "Other ingredients" 52.4%, Mimimum available chlorine 45% The other jar is "chlorinating sanitizer" also from "hth spa" and the ingredients read exactly the same on the label. I called the company to ask what the difference was and the girl said that the differenc was in the "other ingredients" (Sounded like a croc to me. Thats why I am on this forum!) So these are the two products that I have. Having said that, I use either one of them to bring the chlorine level back up to 1-3ppm after use. Both seem to do the same thing. I am not using dichlor. My question is do I "need" the dichlor or can I just continue to add chlorine after each use? Thanks Jim

Hi all I just got a new small (280gal) spa and we love it. Now I am becoming educated on spa water and I am a slow learner. The dealer had me fill it with tap water and add shock and chlorinating sanitizer. I bought a good test kit and I started to test my numbers. The water is clear and clean, but I am adding 1/2 a cap full of chlorinating sanitizer after each use just to keep the chlorine level up. After reading these posts I suspect that the absence of CYA will cause this. Of course my CYA test shows zero CYA (It was never added in the first place)so why would it show anything else right? So my question is with a small spa, am I okay just adding sanatizer after each use and shock once a week or do I really have to introduce CYA to the spa? PH numbers are fine. We have used it for about a month, water smells clean and is crystal clear. No rashes reported and swimwear looks fine. Thanks for the help jim
