I think it's just a bunch of sales hype. The NSPI tech manual only recognizes PHMB (biguanide) as the active ingredient which is a biocide.Sun, 27 Apr 2008 14:33:09 GMTPoolManhttp://www.perfectpoolandspa.com/forum/Topic24-5-1.aspxMy local spa and pool retailer sells Baqua products for both spa and pool. While looking for ways to save a little money on chemistry supplies for my spa I noticed that the ingredients on most of Baqua's spa products are identical to those on their pool products. Yet, you can purchase pool products at a much better per unit weight price.</P><P>When I asked about the difference between two seemingly identical chemical formulations, the retailer conveyed his product rep's assertion that pool products are formulated for cool water temperatures while spa products are formulated for warm water temperatures. After some discussion about that, neither my retailer nor I are convinced that the difference is really about chemistry at all but more about marketing. Even the CAS Registry numbers (when available) are identical and the CAS Registry is a scientific standard independent of any industry or manufacturer.</P><P>In the meantime, I have begun to use some of Baqua's "pool-formulated" chemicals (namely Sanitizer and Calcium Hardness Increaser) in my spa and the water quality is very good. Further, I have not had to change anything else about my chemical regimen to accommodate a different dynamic between spa water and pool product.</P><P>Can any of you substantiate or refute my suspicions?</P><P>Thanks, Earl Scales</P><P>Gainesville, FLMon, 14 Apr 2008 23:55:50 GMTfodderwing
