Water Purification & Maintenance
You Deserve Pure, Crystal Clear Water...
Pure, crystal clear water is part of the reward you
receive for owning your very own spa.And maintaining
water quality is a simple matter when a Use/Maintenance
Routine is established early on in ownership.
Use/Maintenance Routine...
The tasks required to maintain superior water quality are divid-
ed into two categories, Regular and Special.“Regular” tasks
included those that should be routinely performed regardless of
use pattern. For example, the spa filter should be cleaned at a
minimum monthly, even if the spa is used only occasionally.
“Special” tasks are those performed to compensate for increase
in spa use. For example, the filter on a spa that has experienced
a heavy bather load resulting from vacation time and visiting
friends or relatives might need cleaning on a weekly basis or
more. Planning and establishing a routine of Regular and Special
maintenance as required by time and bather load will signifi-
cantly simplify your spa maintenance.
Starting Point For Developing A Use/Maintenance Routine...
No hard set rules can be established for creation of a spa mainte-
nance program since each individual spa has its own unique loca-
tion conditions and bather patterns.The following chart of regular
and special maintenance tasks is meant to provide a starting
point.Water testing and experience will be the final indicators of
what your routine should be.
Water Balance Is Critical
Unlike ordinary drinking water, spa water is held captive in your spa and
is used over and over.All water contains minerals, metals and other dis-
solved solids. In the case of spa water these materials tend to concentrate
due to normal usage and evaporation.Therefore it is critical that you test
and treat your spa water to maintain proper balance.

pH
pH is the measure of the degree of pH acidity or Alkalinity of pool water. Practically
speaking, it tells if water is neutral or how far away from neutral.
pH is a measure on a scale, to which numbers have been assigned, from 1 to 14, 7 is
the middle of the scale and is considered exactly neutral. Readings below 7 are increas-
ingly acidic, above 7 are increasingly basic or alkaline. Under normal conditions, it has
been found that the proper pH for spa water is approximately 7.5 with pH 7.2-7.7
being an acceptable range.The chart above indicates different tendencies at assigned
pH readings and what chemical to add.
Total Alkalinity
Alkalinity represents the amount of alkaline minerals in water. It is the measure of the
buffering capacity or resistance to a change in pH of water. It minimizes changes in pH,
making pH easier to control.Alkalinity and pH are sometimes confused. pH is a measure
of DEGREE of acidity of water.Alkalinity is a QUANTITATIVE measure, telling you the
total amount or quality of alkaline minerals present.The proper alkalinity range is 80-
120 ppm. If alkalinity is allowed to drift, corrosion or scaling may result. Have your spa
water tested periodically for alkalinity by a qualified dealer.
Calcium Hardness
Total Hardness is used to describe the total amount of dissolved calcium and magne-
sium bicarbonates, as well as smaller quantities of other minerals, in water. Unbalanced
water, high in hardness, can cause water to become cloudy. Scale can form inside pipes
restricting water flow reducing their efficiency. Scale can also discolor a spa's
interior.On the other hand, low hardness and unbalanced water can contribute to corro-
sive water conditions.Therefore, a certain amount of hardness is desirable.The desired
range is between 100-200 ppm. Once again, your water should be tested periodically
for hardness.
