Chemistry -Aquafinesse and Spa Frog Inline System

Hello All,

Purchased new Marquis Reward Hot Tub about 10 months ago.

My tub is 350 gallon with dual pumps and filters and has the SpaFrog inline cartridge feature for mineral and bromine or chlorine. I use the grey chlorine with the blue mineral cartridge (not bromine). On initial setup I brought my home water sample to my dealer and they tested it and gave me a printout that they marked up with the chemical regiment to use. I follow the amounts needed to maintain best effort and checked against the Ease Test Strips and monthly sample check at the dealer. Anyway the weekly chemicals (all Spa Guard-the brand they distribute) I use per there direction is and in this order weekly:

Enhanced Shock 1.5 TBS
Chlorinating granules 1 TBS
PH Increaser ~1-2 TSP as needed
Calcium Hardness Increaser as needed
Total Alkalinity as needed
Stain Control 2 TBS
Spa Enzyme 3 Oz.
AquaFinesse 7 Oz.
A different dealer at a recent home show asked me, "why are you putting all of those chemicals in if you have the Spa Frog inline with chlorine"? "You should only need the inline cartridges and monitor your PH, Alkalinity and Calcium. He also said he has never heard of anyone using chlorine AND the Aquafinesse salt solution.

Ive never had a tub before and my dealer states these are the chemicals i should be using.

What should i be adding with the Chlorine Mineral in line SpaFrog canisters?
Why are they instructing me to use a Chlorine and the Aquafinesse together?
Thanks FF

Ive had hot tubs since 2005 and have found over the years of dealing with water conditioning you really only need 4 items, chlorine, acid, baking soda, and a good water testing meter.

All these added filters and floating treatments are super expensive and once you get the basics down using the above products it's simple to maintain.

Wow, you have a much more intense routine than I do. I have ozone and a Natures's2 silver ion cartridge in my spa and I do occasionally shocks with MPS. I can understand a dealer telling you all those chemicals "might be needed" or can be added "as needed" but not all of them as a weekly routine.
