Chemicals for Emerald Spas

disinfectant dialchemcal dispenser Emerald SpaHot tub chemicals used in Emerald Spas are basically the same chemicals that are used by many other spa brands.  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).

Need a replacement chemical dispenser?  We offer these integrated tablet chemical dispensers used in Emerald Spas.

FROG Bromine and Mineral Cartridge System

Some Emerald 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.

6pack bromine cartridges frog Emerald SpaWe offer the replacement mineral and bromine cartridges. Get the best deal on a multi-pack of the larger 200 gram bromine cartridges

We also offer Floating Frog for those that don't have the housing.  

200 Series spas may have a floating Frog rather than the in-line Frog mineral system.

The Spa Frog In-Line system consists of a removable Frog cap, a Cartridge holder, the Mineral Cartridge and the Bromine Cartridge. Need a replacement housing for the Frog Inline system? We offer those too.

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.

Emerald Spa Ozonators

Some Emerald Spas may be outfitted with an ozonator. We offer the APG replacement ozonator with either: DEL APG Ozonator with In.Link cord or DEL APG Ozonator with AMP cord.
Ozone generators come with the parts bag needed to install the ozone generator (including check valve, tubing and instructions).
