How to Maintain a
Hot Tub

Recommended Hot Tub Care
Maintenance Routine

This guide has been written with the
view of making you hot tub water extremely safe, you may find some
guides online that are less stringent. However, we recommend that this
guide is followed as to make sure all risks involved with water care
will be reduced to a minimum, so that you and your family can enjoy your
hot tub in safety.

All the chemicals you need in order to
keep your hot tub in pristine condition can be purchased from
Chemicals Stores.

Daily (before use):
2 minute.

  • Test chlorine levels to see if they
    fall between 3-5 mg/l (ppm) and dose according to the attached
    instructions on the Hot Tub Chorine container.

  • Test Hot tub PH levels to see if
    they fall between 7.2 and 7.6. If not within these parameters use
    Hot Tub pH Plus or Minis according to instructions.

  • If water is foaming use Hot Tub Anti
    Foam. (TIP – Dilute no foam according to instructions into spray
    bottle and spray onto surface of water [do not use bottle for any
    other purposes])

Weekly: Time: 10 minute.

  • Shock Hot tub with suitable
    oxidising agent such as Non chlorine shock or Calcium Hypochlorite.

  • Clean Filter using Hot Tub Filter
    Cleaner and swap with spare. (you should always have a spare filter
    as filters have to be allowed to dry first so that the fibres can
    bind together after cleaning).

Monthly: Time: 5 minutes.

  • If you live in an area with hard
    water (high Calcium) add Hot Tub Scale Remover.

Periodically (Once every 2
months): Time: 90 minutes.

  • Clean hot tub cover with week
    solution of chlorine (3-5mg/litre)

  • Replace hot tub filters (6 months –
    1 year)

  • Change water

Water Balance

It is important to maintain the correct
water balance to create the perfect conditions for you to relax in. We
recommend that you follow the guide below in order to achieve this.

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/lIf 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 Hot Tubs Hardness Plus 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. To reduce this use Hot Tub No Scale to correct the level.
Total Alkalinity
This also depends on your water source
and should be checked every time fresh water is added. The ideal Total
Alkalinity for your hot tub is between 125 – 150mg/l If it stays
between this it will prevent the pH of the water fluctuating. If the
level falls below the recommend amount the water can become corrosive
causing damage to the hot tub equipment. This being the case, we
suggest using Hot Tub pH Plus to raise levels.
If the level is too high, the water can
become poor in clarity and scale will form. To reduce this use Hot
Tubs pH Minus.

pH Levels
It is essential you
regularly check the pH of your hot tub water using Hot Tub Test
Strips. 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 Hot Tub pH
Plus to raise the level and if the pH level is above 7.6 use Hot Tubs
pH Minus to reduce the level.

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. You can use either Chlorine
or Bromine to adjust the levels. Most people use Chlorine, preferring the
smell to Bromine.


Using Hot Tubs Bromine is a very effective
hot tub sanitizer. It comes in tablet forms making it easy to apply to the
The ideal Bromine level is between 3 – 6mg/l


Using Hot Tubs Chlorine is another
effective hot tub sanitizer. It comes in granule forms which dissolve very
quickly in the hot tubs.
The ideal Chlorine level is between 3 – 5mg/l

We recommend that you oxidise your hot tubs
monthly using Hot Tub Non Chlorine Shock. This destroys odours and other
undesirable additions such as perspiration, cosmetics and body oils.
By doing this monthly it improves the comfort and hygiene for hot tubs

Other products also help keep your hot tub
clean, clear and enhance your bathing pleasure.

Control of Foam
to the circulation and aeration of hot tub water, foam can appear on the
water surface which looks unsightly; this is caused by oils and lotions
within the water. To reduce the foam use Hot Tub No Foam regularly to prevent and control
foaming. If the problem of foam continues after using Hot Tub No 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 Hot Tub Water Line Cleaning Paste


Hot Tub Water Line Cleaning Paste should
also be used every time prior to refilling. 

Cleaning the Filter
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


It always a nice touch to add a fragrance
to your hot tub water but never use bath fragrance as this will create
foam which is not good for your tub. Only ever use Hot Tub Fragrances
that have been designed for use in Hot Tubs. Our Online shop sells a
wide range of fragrance.
