Spa Chemicals and Sanitisers
At West Coast Spas we have the biggest range of spa chemicals
in WA. Below you will find information on a few of the different
types of pool sanitisers, including, Nature 2, Spa poppitts, Ozone
Accelerator (Hydrogen peroxide) Spa Chlorine, Bromine and Spa
Here we will cover the basic operation of each of these chemicals,
based on a 1000 litre spa. You have a choice of the four below
systems to choose from when sanitising your spa. Nature 2, Bromine,
Chlorine or Spa poppits. Please note; you can not use ozonator
as the only sanitiser in your spa, you must use a combination
of other sanitisers.
Nature 2 is a mineral sanitiser; it uses silver to kill bacteria,
the sticks last 3 to 4 months and should be changed when the water
is changed. Chlorine and spa shock is used with this system
Start up instructions
Add the stick to the middle of the filter
Fill water to just below the head rests
Adjust ph and alkalinity (usually add about 100g of Alkalinity
increaser) this is in the Perth metro area
Add 1 tablespoon of granulated spa chlorine (then check on a regular
Add 1 tablespoon of spa shock 15 minutes each time before entering
Make sure you clean your filter weekly
Chlorine disappears fast in a warm spa, so make sure you check
it often e.g. add a tablespoon every two days.
Fill spa to just below the head rests
Balance pH and alkalinity
Add 2 tablets to a bromine dispenser and place dispenser in pool.
Add one tablespoon of chlorine (as it takes a day or so for the
bromine tablet to start dissolving and working)
Add 3 tablespoons of spa shock once per week.
If bromine levels are low, open up the dispenser, if levels are
too high, close the windows on the dispenser. Whenever the levels
are low and the spa is to be used, top up with a tablespoon of
spa chlorine, this will boost the sanitiser level and give you
a better reading. Test all levels at least once per week.
A spa can be run just on spa chlorine, note: if you are using
spa chlorine and no other sanitiser, then you will need to keep
the levels pretty high i.e. above 4 parts per million, many people
use a mixture of sanitisers, this helps keep chlorine to a minimum,
helps eliminate the smell of chlorine and also helps get rid of
the used chlorine. Spa shock is reccomended to use with spa chlorine.
Do not use pool chlorine, this can damage your acrylic shell and
Do not use liquid chlorine.
Spa Poppits and Ozone Activator (Hydrogen
Peroxide) This works very well with Ozonators, it allows a total
chlorine free system.
General dosage amounts per 1000 liters water
· Ozone accelerator -this is the main sanitiser- 200 mls
weekly or when needed according to ozone test strips, keep level
at maximum 100 ppm - 10 ppm minimum. Spa Poppits use 400ml per
On the average spas require dosing every 2/3 or 4 days just depending
on spa usage. This routine will depend on spa usage. Always use
gloves. This product can be used in double dosages if required.
· Ozone activator or Quick Fix- used as a shock- 20 to
40 gm weekly or after heavy loading.
Total alkalinity levels must read between 80 - 120 ppm if ta levels
are below 60 ppm do not add ozone activator till total alkalinity
levels have been corrected with alkaline increaser.
· Ozone clear -algae stat- 5 mls per fortnight only do
not overdose this product.
· Ozone Isaac technologies test strips - these strips are
used to test accelerator levels. Test weekly before entering spa
(all dosage amounts are stated on the labels)
(It is safe to enter spa 30 mins after dosing)
Clean filter cartridge once per week with your garden hose, soak
filter cartridge once per month. When using Spa Poppits of Ozone
activator empty your spa every 8 to 12 weeks, use spa pipe degreaser
before emptying the spa.
Ozone machines (ozonators)
These work quite well, not only do they kill bacteria they are
also good at eliminating used chloramines and a number of other
unwanted spa water inhabitants. Ozone machines require little
or no maintenance and some people argue that you do not need to
add as many chemicals.
