Frog Ease Junk?

I have the ease on level 4. We are heavy bathers. The hot tub is used 4 times a day by 4 different people. It seems the frog system is designed for someone that used the hot tub only 3 to 4 times a week. My question is would I be better off with a floater and 1 inch bromine tablets for a 330 gallon hot tub? Right now I am finding myself shocking the tub every two days and cleaning the filter twice a week adding both pH down and alkalinity increased just to keep the levels balanced.

Can someone please provide me with advice to keep a hot tub well maintained for heavy and frequent use?

Temp is between 101F and 103F

Thanks!
