We recommend following these care and maintenance guidlines.
All the chemicals you need in order to keep your hot tub in pristine condition can be purchased here
Hot Tub water Chemicals
Daily:
Test chlorine levels to see if they are between 2-5 mg/l (ppm) and dose
according to the instructions on the 'Stabilised Chorine Granules'.
Or
Test Bromine levels to see if they are between 3-4 mg/l ppm. Adjust
brominator accordingly.
Test Hot Tub/Spa Water PH levels to see if they fall between 7.2 and 7.6. If
not within these parameters use Pure-Spa pH Increase or Decrease according
to instructions.
If water is foaming use Pure-Spa Anti Foam.
Weekly
Shock Hot tub with suitable oxidising agent such as Non chlorine shock
(Oxygen Shock) or Spa Granular Shock (Calcium Hypochlorite).
Due to the build up of Total Dissolved Solids (TDS) the Hot Tub/Spa may need
draining & refilling, this helps to protect against bacteria that can build
up.
Monthly:
Clean Filter using Pure-Spa Filter Cleaner.
If you live in an area with hard water (high Calcium) add Hot Tub Scale
Remover.(coming soon)
Periodically (Once every 3 months):
Clean hot tub cover with week solution of chlorine (3-5mg/litre)
Replace hot tub filter
Water Balance
It is important to maintain the correct water balance to create the perfect
conditions for you to relax in.
Sanitiser: A substance or process which kills or inhibits the muliplication
of pathogenic organisms such as bacteria and moulds.
Sanitising of your hot tubs water is vital to kill bacteria and prevent
algae growth. Levels should be checked regularly using Hot Tub Test Strips
or pool tester kits. You can use either Chlorine or Bromine to adjust
the levels.
Bromine: Using Bromine is a very effective Hot Tub/ Spa Water sanitiser. It
comes in tablet forms making it easy to apply to the water.
The ideal Bromine level is between 3 - 6mg/l
Chlorine: Using Stabilised Chlorine granules is another effective Hot
Tub/Spa sanitiser. It comes in granule forms which dissolve very quickly in
the hot tubs.
The ideal Chlorine level is between 2 - 5mg/l
Shock Treatment
This term describes adding additional oxidising agent for the purpose of
destroying chloramines and algae. It should be carried out when bathers are
not in the pool.
Oxidising
Oxidisation is essential to eliminate organic contaminants introduced by
bathers.
We recommend that you oxidise your Spa regularly using either Pure-Spa Non
Chlorine Shock, or Spa granular Shock. Oxidisation destroys odours and other
organic contaminents such as perspiration, cosmetics and body oils.
By doing this at least monthly it improves the comfort and hygiene for hot
tubs users.
Non Chlorine Shock -Oxygen shock
A non chlorine shock designed as an alternative to using chlorine based
materials. It does not over stabilise the Chlorine and is particularly
recommended for Bromine systems where its use will reactivate the sanitiser.
Add OXYGEN SHOCK at the rate of 12 grammes per 1000 litres of water.
Predissolve in water and add to the Spa. Due to its fast dissolution,
bathers can return to the water in 30 minutes
Shock Chlorine - Spa Granular shock
If pool water has problems of an algea build up or chlorine odour it may be
necessary to increase the chlorine level from its normal 1 to 3 p.p.m to
between 5 an 10 p.p.m. This treatment should be carried out without bathers
in the pool and they should not be permitted to return until the chlorine
level has dropped to its normal level. This process should kill
microorganisms and algae and break down the Chloramines which are
responsible for the undesirable chlorine odour. Use Spa Granular shock (
Calcium Hypochlorite) as this is unstabilised and will release Chlorine
quickly.
Calcium Hardness: It is important to achieve the correct level of calcium in
your water, the levels of which will vary depending on where you live and
where your water supply comes from. Soft water tends to be low in calcium
and hard water tends to be higher. Every time you top up or refill your hot
tub with fresh water you need to check levels of calcium.
The ideal calcium hardness level for a hot tub is between 100 -200mg/l If
the level in your hot tub is below this it could lead to corrosion damage.
If you do find the level is low, then use Pure-Spa Hardness Increase to
bring it up to the correct level. If the level in your hot tub is above this
it can lead to the water appearing cloudy. As a result, calcium can be
deposited on the tub shell, heater element, filter cartridge element and the
pipe work within.
Total Alkalinity
This is a measure of all the alkaline materials in the pool water , it is
present as a pH "buffer"
Total Alkalinity depends on your water source and should be checked every
time fresh water is added. The ideal Total Alkalinity for your Spa water is
between 125 - 150mg/l If it stays between this it will prevent the pH of the
water fluctuating and make the addition of chemicals easier to control
TA lower than 100 p.p.m will cause the pH to fluctuate in an uncontrolled
manner, we suggest using Pure-Spa pH Increase to raise levels.
Levels higher that 200 p.p.m causes the pool water to resist pH changes due
to "overbuffering". water can become poor in clarity and scale will form. To
reduce this use Pure-Spa pH decrease.
pH Levels
If the pH of your water is too high, the efficiency of your Chlorine
sanitiser will be reduced and you may have problems with scaling and cloudy
water.
It is essential you regularly check the pH of your Spa water using Test
Strips or test kits. The ideal pH range is between 7.4 -7.6, this is
slightly alkaline which protects the hot tub and equipment. It also provides
the most comfortable condition for hot tub users and has a good sanitising
efficiency. If the pH level is below 7.4 use Pure-Spa pH Increase to raise
the level and if the pH level is above 7.6 use Pure-Spa pH Decrease to
reduce the level.
It is always better to make several small corrections and retest between
additions.
ph Decrease ("pH minus") An acidic material added to water to lower the pH.
ph Increase ("pH plus") An alkaline material added to water to raise the pH.
pH measurement
This may be carried out by test sticks or papers, colourimeter test or by
using a pH meter.
Control of Foam
Due to the vigorous circulation and aeration of spa water unsightly foam can
appear on the surface of the water, especially when oils and lotions are in
the water.
To reduce the foam use Pure-Spa Anti foam regularly to prevent and control
foaming. If the problem of foam continues after using Pure-Spa Anti Foam we
recommend that you drain and refill with fresh water.
Cleaning your Hot Tub - At the waterline, grease and rubbish can build up
that creates a line around the tub which provides an ideal ground for
bacteria and algae to breed. To remove these lines easily and prevent them
appearing use a Spa Water Line Cleaning Paste daily. (coming soon)
Cleaning the Filter Cartridge - You will be able to tell when the filter
needs cleaning as the circulation within the hot tub will be reduced and the
water cleanliness will change.
To avoid the inconvenience of the filter not working we recommend that it
should be cleaned at monthly intervals or more if you use your hot tub
heavily. Hot Tub Cartridge Cleaner helps clean and restores filters to their
full efficiency.
Fragrances - It always a nice touch to add a fragrance to your hot tub water
but never use ordinary bubble bath fragrance as this will create foam which
is not good for your tub. Only ever use Non foaming Spa Fragrances that have
been designed for use in Hot Tubs.
KEY SPA CHEMICAL PARAMETERS
Sanitiser (Chlorine) 2-5 mg/l (ppm)
(Bromine) 3-6 mg/l (ppm)
pH 7.2 - 7.6
Total Alkalinity 80 - 160 mg/l (ppm)
Calcium Hardness Min 100 mg/l (ppm)
N.B. Spas fitted with devices such as ozonators will still need a residual
sanitiser (Chlorine/Bromine) for treating ongoing spa pollution.
