CHANGING THE HOT TUb WATER
A hot tub should be drained every 8-12 weeks, depending on
size and amount of use. If your hot tub is used daily or by a
large number of bathers, the water should be drained more
often. One method to determine the approximate length of
time between water changes is to divide the water volume
(in liters) of your hot tub by 13.5 and then divide by the
average number of bathers each day.
( ) (
Formula ________ ÷ 13.5 ÷
Volume of water
in litres
) ( )
__________ = __________
Average Days
daily bathers between
water
changes
ExAMPLE:
1000 liters divided by 13.5 divided by 2 = 37 days.
The hot tub water must be changed when the amount of
dissolved solids becomes excessive, and is usually
indicated by "gray" or dull looking water.

WATER SOFTENERS

Never fill a hot tub with water from a water softener, as
it could adversely effect the water chemistry, making it
difficult to maintain proper water balance. If you live in
an area with hard or soft water, give careful attention to
your Calcium Hardness level. Topping Up with soft water
is acceptable.
