STARTING
YOUR SPA
WATER CHEMISTRY GUIDELINES
There are several methods available to sanitize the spa water. We recommend using
chlorine or bromine in conjucnction with your ozonator. No other oxidizing agents
are suggested. Use of other oxidizing agents may damage equipment and void the
warranty.
Shock Sanitation:
After filling your spa, shock sanitize the water before using the spa. This treatment
provides initial sterilization as well as kills any algae spores that may be present and
oxidize undesirable minerals and organic matter in the raw water. Repeat shock
treatment anytime the spa is refilled or the water has lost its chemical control due to
neglect.
We recommend the use of sodium dichloracyanurate (DyCloro) or lithium hypochlo-
rite. Calcium hypochlorite is used for swimming pools and is not recommended for
spas. Tri-Cloro is not recommended either.
It’s important that you read and follow the safety tips for chemical usage and storage
listed in the Water Treatment Guide. (Also see RECOMMENDED CHEMICAL LEVELS
under TROUBLESHOOTING.)
