Welcome to our forum.
...I am using the spa frog system that came with the spa. I have the Bromine opened all the way (setting six). Our PH is very high here...it is PH 8 right out of the tap. I have been adding what the dealer gave me to get the PH down. Ph is now 7.8 and Total Alkalinity is between 120 and 180. With the bromine opened all the way my reading is still between 0 and 1. The water has a haze to it...
If that isn't the problem, I'd try a 2-3 TBS dichlor shock treatment, and see if you still have a residual of 1ppm or better the next day. If not, you probably have something growing in the tub, so keep dosing until you clean it up and are able to maintain a residual. Then figure out the feeder problem. Regarding your regular shock routine: you didn't state what you are using or the dose. Depending on your usage, you may need to shock more frequently.
