Lantern88,
Our SpaNaturally product is compatible with ozone and UV (Clearray) although most of our customers find they do not need them once they have starting using SpaNaturally. Neither SpaNaturally or PoolNaturally are sanitizers and therefore need to be used with an approved sanitizer. Besides significantly reducing the overall chemical demand of your spa (sanitizer, de-foamer, acid, bi-carb, etc), SpaNaturally also binds positively charged ions such as heavy metals and calcium which in turn keeps maintenance down on your spa and your UV running more efficiently. If you have questions about biofilm and how it works I encourage you to take a look at Montana State University's - Center for Biofilm Engineering Webiste. Once you know how biofilm works -traditional sanitizers cannot penetrate through the protective coating biofilm secretes - it starts to explain so many of the issues spa/pool owners have with water chemistry imbalance and the ever growing need for more chemicals to try to achieve water balance.
If you have any additional question, please free to ask. Thank you in advance.
