We recommend that you purchase your chemicals from your authorized L.A. Spas dealer. The dealer
can also advise you on alternative methods for water sanitation.
Use of the wrong chemicals can be
dangerous and may void the warranty on your spa.

pH CONTROL
All water has a pH value determined by a scale of 0-14, which is a measure of the acid to alkaline
relationship. While a pH reading of 7.0 is considered neutral, a lower reading is considered acidic and a
higher reading is alkaline. The proper pH for spa water is between 7.2-7.6. High pH (above 7.8) can
reduce sanitizer efficiency, cloud the water, promote scale formation on spa surface and equipment and
interfere with filter operations. When pH is too high, add a pH decreaser. Low pH (below 7.2) is equally
damaging and can cause equipment corrosion, water that is irritating, and rapid sanitizer dissipation.
Add pH increaser to adjust the level. Follow the chemical manufacturer’s directions and procedures
when adding chemicals to spa water.
NOTE: Always add pH adjuster with jets operating and circulate all chemicals for at least 30 minutes.
Remember that good pH control and sanitation are absolutely essential for proper spa water treatment.
TOTAL ALKALINITY
Total alkalinity is the amount of carbonate, bicarbonate, and hydroxyl ions in the water. Total alkalinity
affects and buffers the pH of the water. With high total alkalinity (above 160), pH resists adjustment.
With low total alkalinity (below 130), pH is unstable and difficult to keep in the ideal range. Proper total
alkalinity levels allow other spa chemicals to work effectively.
WATER TREATMENT
SANITIZERS
The importance of maintaining an adequate level of sanitizer in your spa cannot be overemphasized.
Warm water presents a fertile environment for the growth of bacteria and viruses. This growth is
prevented when adequate sanitizer levels are continuously maintained.
WARNING – Sanitizers such as tri-chlor (tablets or sticks), calcium hypochlorite, sodium hypochlorite,
and any chemical that dissolves on or remains un-dissolved in contact with the spa surface will damage
your spa surface and will void the warranty completely.
BROMINE
Bromine is the most common sanitizer used in spas. Adjust the floater to maintain a total bromine level
of 3.0-5.0 ppm. If the reading is below the minimum, raise the level before using the spa. If the reading
is above 5.0 ppm, allow ppm to drop to the proper range before using the spa. Brominating tablets are a
convenient and effective source of bromine for your spa. Do not drop bromine tablets directly into the
water as this may damage the spa surface. A chemical “floater” safely and properly dispenses the
tablets into the spa water. When used properly, brominating tablets will keep you water clean, clear,
and odor-free. To ensure maximum effectiveness, add ½ oz. of sodium bromide per 100 gallons of
water every time you fill your spa. This will establish a bromide reserve.
