Chemicals for Marquis Hot Tubs

disinfectant dialChemicals used in Marquis Spas are basically the same chemicals as are used in many other hot tub brand spas.  It is important to have a sanitizer (bromine or chlorine) and monitor the pH.  Many Emerald Spas are outfitted with a disinfectant dispenser that uses bromine or trichloro-s-triazinetrione tablets (1 inch diameter).

Some Marquis Spas come standard with the Spa Frog In-Line system, so you just need to replace the bromine cartridge and mineral cartridge regularly and monitor the water chemistry with test strips.

There is a dial on the top that adjusts the sanitizerlevel for both dual and single filter systems.

The Spa Frog In-Line system consists of a removable Frog cap, a Cartridge holder, the Mineral Cartridge and the Bromine Cartridge.

Never open the Frog cap when the jets are running.  To open, remove the holder by pushing down and turning clockwise then pull out to access the holder. Remove and replace the mineral cartridge (top part) and the bromine cartridge (bottom part). 

The mineral cartridge can be adjusted and should be replaced every 3-4 months or so depending on spa use.
