Bromine:Chemical used to sanitize
water. A level of 3.0 to 5.0 ppm should be maintained.
pH (potential Hydrogen): A scale of
1 to 14 that measure the alkalinity of the water. A reading below 7.0 equals
acidic water and will cause etching of the plaster, staining and corrosion to
the metal pipes and heater and could be irritating to swimmers. If the pH is
above 8.0 the water will be cloudy, scale will build up along the tile and in
the pipes. The filter will become clogged and circulation will diminish. A high
pH also makes chlorine less efficient but Bromine works OK at a pH of 8.0. In
A Fiberglass spa keep the pH at 8.0 or above.
Demand: If the
pH is above 7.8, use the #3 test solution 1-drop at a time to determine how
much acid is required to bring the pH down to the ideal range of 7.4 to 7.6.
Count the number of drops and compare against the chart in the test kit to
determine how much acid. NOTE*** Dry acid is preferred when adjusting spa water.
is a buffer for the pH. The ideal range is 80 to 120 ppm. If the Total
Alkalinity is above 120ppm the pH will drift up (above 7.8) and the demand for
acid will be higher. If the Total Alkalinity is below 80ppm the pH will drift
below 7.4 and Base will be needed to raise the pH on a regular basis. The pool
will also be prone to blue stains.
Base: When the pH is below 7.4, a
Basic (opposite of acidic) product will be added to the pool to raise the pH.
The name of this product is Soda Ash. This should not be needed and only used
if the chemicals are allowed to be out of range for extended periods of time.
T.D.S.: Total Dissolved Solids can be
tested at the local pool store. Check every other month. The maximum reading is
2000 to 2500 ppm, if above 2500 ppm drain pool. T.D.S. is a measurement of ALL
dissolved particles in the pool. Everything leaves some particles behind.
Chemicals, dirt, people etc. all leave some TDS and over time the measurement
rises. Liquid chlorine is the biggest contributor to this reading. When the
pool has a high T.D.S. level people may complain the pool “tastes salty”. A
high T.D.S. level won’t cause damage but will make the chlorine a lot less
efficient and the cost of chemicals will be more.
Conditioner:Made from Cyanuric acid and is
used to preserve chlorine levels in the water. The ideal range is 40 to 80 ppm.
This chemical is added when the pool is filled and on a periodic basis. Test
for this chemical with a Cyanuric acid test kit. Not used with Bromine
Algaecides: Kills algae. Identify the color
of the algae and the location of the algae. Common colors in California are
Green algae, Yellow (mustard) algae, and Black algae.
Scale: Deposits of calcium on the tile
and plaster, caused by high pH.
How to maintain Spa Water Chemistry –
Using Bromine Tablets
Floating Bromine Dispenser
Bromide (1 oz added each time spa is drained and re-filled)
Time “Metal Gon” (Add 1 pint bottle each time the spa is re-filled)
Shock (often sold as Renew) (individual 1oz packets or 2lb bottle)
increaser (Raises Ph. Often sold as Spa Up)
·Spa clarifier (Look for a product that is a 4 in 1 and contains enzymes)
Buy: Purchase these items from a POOL SUPPLY…..NEVER PURCHASE SPA CHEMICALSFROM HARDWARE STORES!!!Their products are terrible.
water with test strips (designed for use with Bromine)
test strip in water and hold flat for 15 seconds and compare colors to chart
best results do this out of direct sunlight)
Check the reading of the pH and Total
Measurement of 7.4 to 8.4 is ideal for Bromine. If it is higher don’t worry. If
it is lower add 1 cap-full of Spa Up, allow water to circulate for 15 minutes
and re-test. Repeat if necessary (up to 3 times. If you cant get it to come up
either drain spa and re-start or bring sample of water about 1 pint to your
local pool supply and ask them to test it for free). If the water tends to be
lower than 7.0 each time you test the water it is probably time to drain the
spa water and start fresh.
Alkalinity:Readings of 110ppm and above
are desired. If the readings are below
80ppm drain the spa.
If the pH
and Total Alkalinity are OK then proceed.
With a Bromine sanitized spa it will
be very simple to maintain fresh clean water.
Bromine has a reading of 5.0 or better you have plenty of sanitizer.
Bromine Level is too high just
remove floating bromine dispenser (the floater).
Bromine level is below 3.0, Verify
that the floater has tablets (3 to 4 (or the equivalent of lots of little
pieces of bromine)) and the floater is set to # 3 or # 4. (On the side of the
floater are numbers, Close the floater until these numbers are exposed. Lock in
place with locking ring.) Add tablets if necessary.
of Non-Chlorine Shock (Renew) will instantly activate the Bromine in the water
and you will have a healthy Bromine Reading (above 3.0).
Always wait 15 minutes before you add
additional chemicals and always add chemicals with the filter on.
a bathing suit to the spa and NEVER
wash it. Laundry soap causes foaming.
just a small shot of Foam Down if spa has Excessive foam (may cause cloudiness)
Spa Cover is ESSENTIAL…. It prevents
the sun from burning out the Bromine
the water 1 time per week and again before
1 oz of Spa Clarifier each week to help the filter (preventative maintenance).
high pressure garden hose clean filter pleats each month
Spa 3 to 4 times per year (it’s just a big bath tub).
add the chemicals to the water…never add the water to the chemicals!!!
at a 2lb. container of Spa Up on-hand and hope the ph just stays high and that
you do not need to add it at all.
the spa for approx. 3 hours per day
try to balance the pH. Its just too hard to do. Just keep it at 7.4 to 8.4 and
if it goes higher don’t worry. Only pH BELOW 6.8 is bad for both your skin and
the spa equipment
·Trust your instincts…. If the water
looks good and SMELLS good then you are probably OK. But if it SMELLS bad or is
Cloudy or Discolored there is definitely a problem!
may be strong fumes when you remove the cover if the spa is heated but that
should go away immediately. Choking and coughing are not normal.
should be LESS of an irritant than Chlorine.
