MAINTAININg ThE SANITIzER lEvEl
A. Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted organisms from growing in the spa. At the same time, you don’t want
too high a sanitizer level, or it can irritate your skin, lungs, and eyes.
B. Always maintain the sanitizer level in your spa at the recommended level for each type of sanitizer.
C. Watkins recommends the following sanitizer:
• FrOG sanitizing system (mineral and bromine).
D. Watkins also approves the following sanitizers:
• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)
• Biguanide
• Bromine
WarNING: DO NOT use tri-chlor chlorine or any type of compressed bromine or chlorine, acid or any type of sanitizer which is not recommended by Watkins
Manufacturing Corporation.
FrOG wATER CARE SYSTEM
(ThE FrOG MINERAl CARTRIdgE IS NOT APPROvEd FOR USE IN CANAdA.)
The FrOG Water Care system is comprised of the following products:
THe FrOG MINeral CarTrIdGe . This cartridge introduces minerals into the spa water, inhibiting bacteria growth.
THe FrOG BrOMINe CarTrIdGe (BCdMH).
The only recommended sanitizer that will work in conjunction with the
FrOG
Mineral cartridge.
IMPOrTaNT: In addition to regularly testing and balancing your spa water, a weekly "shock treatment" is required. The shock treatment quickly destroys any remaining
contaminants while revitalizing the bromine in the water.
To weekly “shock treat” your spa, we recommend that you use either MONarCH MPS Plus or sodium dichlor (chlorine). Sodium dichlor may be a more appropriate
weekly shock for those users that experience heavy bather load conditions.
The following optional products can be used in conjunction with the
FrOG
Water Care system:
MONarCH MPS PlUS NON-CHlOrINe SHOCK (MPS/Monopersulfate) is an oxidizing chemical used to prevent the buildup of contaminants, maximize
sanitizer efficiency, and improve water clarity. When used in conjunction with the FrOG system it oxidizes particulates in the spa water.
IMPOrTaNT NOTe: MONarCH MPS Plus is an oxidizer, not a sanitizer.
MONarCH CHlOrINe is an efficient sanitizing chemical for spas and can be used for the required weekly “shock treatment” when using the FrOG water care
system. Watkins Manufacturing Corporation recommends the use of sodium dichlor-type granulated chlorine because it is totally soluble and nearly pH neutral.
MONarCH COrONa dISCHarGe (Cd) OzONe is a high output ozone system and is the only ozone purification system approved for installation in your
Caldera Spa. The MONarCH ozone system utilizes CD technology to produce a higher concentration of ozone than is produced by a competing
chip style CD or ultraviolet light ozone systems.
