Chemical Start-Up Instructions

Once you have filled your Spa with water, you will need to add your preferred Sanitiser.  Ideally wait until the Spa is above 20 degrees Celsius so the chemicals will dissolve quicker.  Add chemicals as instructed below with pumps on, leave for 5-10 mins before replacing cover.  

The most commonly use sanitiser and an effective way to kill bacteria in your water. If you have skin reactions to Chlorine then you can use Bromine, the only downside to Bromine is that it is a slower reacting chemical and not as effective at killing bacteria.
Chlorine Granules                                                                                            Level 3-5 PPM
If you are using Chlorine Granules you need to keep your level of Chlorine between 3-5 ppm (parts per million). Simply sprinkle the granules into the water with the pumps on, leave for 5-10 minutes then turn off the pumps and replace the cover.
Favoured and recommended by many Spa and Hot Tub suppliers, as it is kinder on the skin particularly if you have children, it is also less volatile at high temperatures.

Bromine Granules                                                                                           Level 4-6 PPM
If you are using Bromine Granules you need to keep your level of Bromine between 4-6 ppm (parts per million). Simply sprinkle the granules into the water with the pumps on, leave for 5-10 minutes then turn off the pumps and replace the cover.

Dosage Instructions for Chlorine/Bromine Granules
Commissioning &
New Water (Shock)
Add Chlorine
600-800 1 & ½ Teaspoons ¾ Teaspoon ¾ Teaspoon
900-1200 3 Teaspoons 1 & ½ Teaspoons 1 & ½ Teaspoons
1300-1500 4 Teaspoons 2 Teaspoons 2 Teaspoons
1600-1800 6 Teaspoons 3 Teaspoons 3 Teaspoons
One level teaspoon holds approx. 5g of dry product.  For commissioning and new water, you will need to shock dose to establish your water.  Leave for 24 hours and check your levels with the Test Strips, maintain the pH balance between 7.4 and 7.6 and alkalinity level of 125ppm – 150ppm.

IMPORTANT NOTE: On first start-up of fresh water you will use more sanitiser, after 24 hours once heated check levels with test strips and add more sanitiser as required.  Also note, the more people using the Spa the more sanitiser you will need to add.  Lack of sanister can cause your water to go cloudy.
Bromine Tablets
A very easy to use and cost effective sanitiser, simply put 3-5 tablets in a floating dispenser and adjust the collar accordingly. Allow 24 hours for the tablets to take effect and check bromine levels with ph Test Strips, maintaining a bromine level of 4-6 mg/l.  Tablets will take 10-14 days to dissolve, check regularly and keep between 3-5 tablets in dispenser always.


Chlorine tablets regardless of the brand, contains a chemical called Trichlor (Trichloroisocyanuric Acid) which is highly corrosive and when used in an acrylic hot tub, they can cause severe damage to the shell and its components.

If you have ordered the Chemical Start Kit, you will also receive the following items:-

Pool Clean (Water Clarifier)

Small particulates of dirt or foreign matter that are below 20 microns usually pass through the filtration systems of spas and can leave the water looking cloudy. Pool clean is a liquid product that flocculates (coagulates) these particles into larger clusters so they can be filtered out of the water. Once you have used Pool Clean make sure you jet wash your filters. Add as instructed on bottle.

Non-Chlorine Shock

Non-Chlorine Shock is an oxidiser that will directly oxidise the waste itself.  This is ideal to use in Spas with heavy usages, it does not use chlorine, it does not smell as strong as chlorine and it eliminates waste and odour in the water before it takes hold.  You can also use this with new water and/or add a dose on a weekly basis to prevent your water from deteriorating.  Add after bathing as instructed on the bottle with the circulation pump running.  To be used in conjunction with your preferred sanitiser.

PH Minus (reducer)

The effectiveness of all chlorine based sanitisers decreases as the pH level of the water increases. pH reducer can be added directly to the water to reduce the pH to a desirable level. For the chlorine to remain effective, the pH level should be kept below 7.6. However, if the pH level drops too low then the water can start to degrade pumps and liners, so aim to keep the pH level between 7.4 and 7.6 pH.  Add as instructed on bottle.

PH Plus (Increaser)

Bathing water that is low in pH can be corrosive to pool pumps, heat exchangers and damage the pool lining. pH plus can be used to raise the pH to a desirable level. However, too high a pH level and the effectiveness of all chlorine sanitisers starts to decrease. Always aim for a pH level of between 7.4 and 7.6. pH. Add as instructed on bottle.


Antifoam will eliminate foam which is built up from such products like sun cream, fake tan, oils and many cosmetics. This chemical will disperse foam build up instantly. Disperse over the water at the rate of 25ml per 1000 litres. Once you have used Antifoam, make sure you clean your filters.

3 in 1 test strips

These test strips test the levels of Free Chlorine/Bromine, pH & Total Alkalinity to keep you and your family safe.  To use dip a strip into water and remove immediately, hold strip level for 15 seconds (do not shake excess water from strip).  Compare Free Chlorine/Bromine, pH and Total Alkalinity pads (in that order) to colour chart on label.
