Thanks RDspaguy, I think I'll take your advice. I'll by a mineral something or other (probably the PoolRx) and buy a bunch of granular Dichlor. I have found dichlor handy for lots of things over the years. My 360 gallon Bullfrog spa does not have an ozonator. Being cheap to the bone, I figured I didn't want to replace a ($70 bulb every year). Thanks again!

Clorox responded: "Thank you for contacting Clorox® Pool & Spa™. Unfortunately our Shock XtraBlue, Shock Plus, Oxi Chlorine Free Shock Oxidizer and Salt Pool Shock Oxidizer are meant for Pools use only.The copper in our shock is for algae prevention, not mineral cartridge substitution. We do have our Clorox Spa All-in-One Sanitizer and Shock, which is meant for spa use." So even though their product is labeled as being for Pools and Spas, it isn't for spas! In my spa some years ago, I just used dichlor (plus adjusted for ph and alkalinity) and things seemed to go smoothly. I didn't know about cyanuric acid build-up back then. I'm years older now, but still not savvy enough to deal with that problem. I just can't use dichlor for my routine sanitizer and weekly shock. I wish it were as simple and cheap as it use be be (when I apparently was doing it wrong). The mineral/chlorine systems seem pricey to me, but they do check off the simple box for me. the mineral systems I see are Frog@ease, Nature2, and PoolRx. My spa came with frog@ease triangular cartridges that click into a holder besides the filters. I don't know where I can get these other than the dealer 35 miles away. Nature2 reportedly cant't be used if the cartridge won't fit in the filter, which is the case with my filters. PoolRX is the longest lasting and cheapest for the mineral part, but it seems like an unfamiliar option. I will have to study more about what they want for chlorine.

Thanks for the reply RDspaguy. I read the article, but I don't have a high enough IQ to follow all of those directions. Given the choice between cheap and easy, I'll have to opt for easy. My Bullfrog spa came with the frog system...smartchlor cartridges and a mineral cartridge. May just have to stay with that or Nature2.

Well, I too am confused. I bought 40 lbs of this stuff online from Costco. I thought that surely Clorox would provide instruction for spa usage since it it says "pool and spa". I don't recall the word "spa" ever appearing on the package other than in the name. Certainly no directions for spas and, like Eight0Eight, no response from Clorox to my email. I haven't used it and I guess I'll have to return it since there are zero instructions for spa use. I assume the copper would be in low levels so I wouldn't be worried about green hair. I'm running low on supplies and want to come up with something affordable and easy. Damn!
