Welcome to our forum.
The frog is an automatic feeder for your sanitizer. Here is how most people sanitize a spa; pick any day of the week, lets say Sunday. You test your spa and throw in some sanitizer (i.e. bromine, chlorine, ect.), Monday you have to much, Tuesday still pretty strong, Wed getting better, Thursday the water is starting to go south a bit, Friday low sanitizer, Saturday nasty water. What the frog system does here is give you a constant feed of bromine and minerals to keep the spa clean all week with babysitting it. Everyone gets into their own system of taking care of (or not) their spa. The Frog system just makes that a bit easier.
