HOT TUB WATER BALANCE – GENERAL OVERVIEW
NOTABLE POINTS
• The reliability and longevity of your hot tub support equipment
are directly related to how well water quality is maintained!
• The small volume of water in your hot tub is easily affected by
the introduction of oils, lotions, perspiration and chemicals. It is
imperative that you give your hot tub regular attention to main-
tain clean, safe and balanced water to prevent premature dam-
age and/or failure (corrosion/calcification) to the support equip-
ment. Maintaining proper hot tub water balance and sanitizer
levels is extremely important. Neglected hot water will allow
bacteria to quickly spread.
• The mineral content of hot tub water increases due to water
evaporation, sanitizers and other chemicals. If the mineral con-
centration, particularly calcium, becomes too high, the minerals
will literally “drop” or precipitate out of the water and deposit on
the hot tub walls, plumbing, jets, in the filter and on the heater
element.
• It is very important that pH be checked frequently and main-
tained in the recommended range as indicated in the chart
WA-
TER BALANCE
SUMMARY FOR YOUR HOT TUB
• It is also very important that Total Alkalinity (the ability of the
water to resist a change in pH) be maintained in the recom-
mended range as indicated in the chart
WATER BALANCE
SUMMARY FOR YOUR
HOT TUB
• Although there may be two identical hot tub models right next
door to each other, the maintenance requirements will be differ-
ent, dependant on such factors as:
– bather load
– frequency of use/quantity of bathers
– different body chemistry
– sun vs. shade
– temperature
For these reasons, it is very important to develop proper hot tub
water maintenance habits and follow your Hydropool retailer’s
recommended water maintenance procedures.
• Never pre-mix chemicals with each other
prior to adding to hot tub water.
• Add only one chemical to the water at a time.
• Always add chemicals to water and not vice-versa.
• Chemicals may be corrosive, so handle with care and
store in a cool dark place.
• Never smoke near chemicals as most are flammable
• Ensure any spilled chemicals are carefully cleaned up
immediately.
• Always have the POISON CONTROL telephone number
handy in the event of an emergency.
• Keep chemicals out of children‘s reach
• Wear safety glasses and gloves when handling chemi-
cals.
Heater and other component failure due to
improperly maintained pH or Total Alkalinity
is not covered under warranty.
CHEMICAL HANDLING SAFETY HINTS
INITIAL WATER FILL & BALANCE
1
Make sure the hot tub water is circulating and above 20°C
(68°F)
2
Add a sequesterant (stain and scale controller). Allow water
to circulate for an hour before adding anything else to the hot
tub water.
3
Add a Shock / oxidizing agent .
4
Add sanitizing tablets (Bromine or Chlorine) to the dispenser:
Built in dispenser
: if your Hydropool hot tub was ordered with
the optional built in bromine/chlorine dispenser, (located under
the basket of the cartridge filter housing),
refer to section
CARTRIDGE FILTER for details on removing and re-
installing the lid.
Once the filter lid is removed, you’ll notice a
clear 2.5 cm (1 in.) tube extending from the bottom of the bas-
ket. Expose the large Refill hole at the end of the tube and add
5 or 6 tablets. Do not overfill dispenser as performance will be
affected. Turn to expose the most number of smaller holes and
allow water to circulate for 3 to 4 hours
before testing level. Adjust to lesser num-
ber of holes as necessary to maintain a
level of 2-4 PPM Sanitizer.
Floating dispenser
: As above, add 6 or 7
tablets, adjust initially to ‘5’, allow water to
circulate for 3 to 4 hours, then test. The
tablets will dissolve slowly over a 10-14
day period, depending on dial setting, and
use of the hot tub.
5) Test pH and Total Alkalinity and adjust
accordingly.
