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 only the following sanitizers:
• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)
• Brominating Concentrate
™
(one step granular bromine)
• Baqua Spa
™
(please consult your Baqua Spa
™
manual for instructions on the use of this product).
WARNING:
DO NOT use tri-chlor chlorine, bromo-chloro-dimethyl-hydantoin (BCDMH), or any type of compressed bromine or chlorine, acid or
any type of sanitizer which is not recommended by Watkins Manufacturing Corporation.
EVERFRESH
®
WATER CARE SYSTEM
The EverFresh
®
water care system is comprised of the following products:
• FreshStart
®
10,000
Pre-filter
• Sodium Dichlor
• Monopersulfate (MPS)
• FreshWater
®
III high output ozone system
• FreshWater
Ag+
®
silver ion purifier
FreshStart
10,000
Pre-filter
is used when filling a spa for the first time or at refill. It attaches to a garden hose and filters out rust, dirt, detergents, algae
and chemicals.
Sodium Dichlor (chlorine)
is the only recommended sanitizer that will work in conjunction with all of the other products in this system.
FreshWater III high output ozone system
uses Corona Discharge technology to produce a high concentration of ozone which is injected into the
spa water.
Monopersulfate (MPS)
is an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined
chlorine, and improve water clarity.
FreshWater
Ag+
silver ion purifier
introduces silver ions into the spa water, inhibiting bacteria growth. When combined with MPS, or chlorine,
oxidizes particulates in the spa water.
It is important to follow the recommended application and maintenance programs outlined for each product’s use.
If the spa is being used over an extended period of time, such as a whole afternoon or evening, additional sanitizer will be needed.
