SWIM SPA WATER BALANCE – GENERAL OVERVIEW
NOTABLE POINTS
• The reliability and longevity of your swim spa support equip-
ment are directly related to how well water quality is maintained!
• The small volume of water in your swim spa is easily affected
by the introduction of oils, lotions, perspiration and chemicals. It
is imperative that you give your swim spa regular attention to
maintain clean, safe and balanced water to prevent premature
damage and/or failure (corrosion/calcification) to the support
equipment. Maintaining proper swim spa water balance and
sanitizer levels is extremely important. Neglected hot water will
allow bacteria to quickly spread.
• The mineral content of swim spa 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 swim spa 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-
WATER BALANCE SUMMARY FOR YOUR SWIM SPA
• 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 SWIM SPA
• Although there may be two identical swim spa 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 swim
spa water maintenance habits and follow your Hydropool re-
tailer’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.
INITIAL WATER FILL & BALANCE
1 Make sure the swim spa is circulating.
2 Add a sequesterant (stain and scale controller). Allow water
to circulate for an hour before adding anything else to the swim
spa water.
3 Add a Shock / oxidizing agent .
4 Add sanitizing tablets (Bromine or Chlorine) to the dispenser:
Your Hydropool swim spa
comes with a built in bromine/
chlorine dispenser, (located in
the lid 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”) di-
ameter tube extending from
the bottom of the lid.

WARNING
CHEMICAL HANDLING SAFETY HINTS
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 largest area and allow water to circulate for 3 or
4 hours before testing level. Adjust to lesser area 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 setting, and use of the hot tub.
5 Test pH and Total Alkalinity and also adjust accordingly.
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 largest area and allow water to circulate for 3 to 4 hours
before testing level. Adjust to lesser area as necessary to maintain a
level of 2-4 PPM Sanitizer.
