appear to be cloudy. This indicates that your
filter may be fouled and should be cleaned
immediately. If after cleaning the filter, the
water remains cloudy, check pH and TA. If
cloudiness still persists, introduce water
clarifier. This J)roduct is formulated to suspend
part iClJ late matter to form large enough
particles to be trapped by your filter. Also
you will use less chlorine or bromine because
the water clarifier removes and neutralizes the
particles before the chlorine or bromine has
time to oxidize them.
The pH scale runs from 0 to 14, with 7.0
being the neutral or mid-point. any pH less
than 7.0 is on the acid side of the scale: the
closer one comes to a pH of 0.0 the more
corrosive th~ water. Any rH greater than 7.0
is on the bi)sic or alkaline sirle of tIle scale; the
closer one comes to a pH of 14.0 the more
caustic tl)e water. It is generally agreed that a
f)H in the range of 7.4 to 7.8 is the most
comfortable and desirable level.
If frequent dosages are indicated and the
water continues to remain cloudy, you will
need to drain and refill you spa.

4.3.7 FOAMING:
Foaming is caused by shampoo and soap
residues, hair sprays, cleansers and even "soft"
water -low total alkalinity and calcium
hardness. When air is bubbled through water,
surface tension tends to create a film on top
of the water which, in fact, does not allow the
air bubbles to pop. These bubbles begin to
form on the surface and have the appearance
of foam.
In order to reduce the foam, the use of No
Foam is recommended. This product
immediately reduces surface tension by
breaking down the oils and removing them
through filtration. Squirt a small amount of
No Foam across the surface of your spa water.
If you find that it does not accomplish
defoaming of the water within one hour,
repeat the dosage. If several applications are
required, this is an indication that the spa
should be drained and refilled with fresh
water .
4.3.4 ALKALINITY:
Total ulkalinity, as opposed to pH, is the
rlllantitative measllrement of the alkaline
material, bicarbonates, hydroxides, etc.
rresent in the water which acts as a buffer
against rapid pH chan(]e. Slla water should be
tested regularly to determine the total alkali-
nity which should be in the ran!le of 90 to 120
ppm. -90 bein~J the ideal. To raise T A, use
SodilJm Bicarbonate (baking soda) which
raises the alkalinity rapidly. It also will raise
the pl-f slowly.
ACID OR TRI-CHLOR MUST NOT BE
USED. IT WILL RUIN YOUR SPA FINISH.
4.3.5 CALCIUM I-IARDNESS:
Total hardness is made up of pissolved calcium
IJlus smaller quantities of other mi~eral salts
including Inagnesium. It must be noted that
the amour It of calcium hardness present will
vilry from one spa to another and is what
dictates water balance. The higher the calcium
hardness level the lower total, Cjllkalinity;
conversely the higher the TA the ,lower the
cillcium hardness one should maintain. Water
will tend to halance itself hy leaching calcium

4.3.8 COLORED WATER/SCALE FORMATION:
Colored water is generally caused by: the
presence of metals such as iron, copper and
manganese. They can be present as metallic
ions in solution or as finely divided particles
of metallic compounds in suspension. Each
metal imparts its own characteristic color to
the water when oxidized by chlorine or
bromin~. Iron produces a reddish brown tint.
Copper causes the water to appear blue-green
and when manganese is present, the water
takes on a dark brownish black hue.
Because minerals and metals are generally
present ill the fill or make-up water, a proper
chelating agent should be used to hold these
minerals and metals in suspension to prevent
scaling ilnd corrosion.
