THank you all. I ended up finding some at the pool store. They said it’s not the same stuff that came in my kit “First Aid Kit”, but it should work the same. THey said prety much the same thing Jordan C said. You DO have to put some chemicals, but most of them you dont have to use. The guy at the pool store said becuase of the ozone system we have in our Barefoot Spa, we dont hav eto use many chemicals, and they include the first aid kit just as a precaution. All I ended up buyin gwas more pH Up and more chlorine shock. He said I can prety much throw the rest of the stuff away becuase I wont need it.
