What Are Acceptable Ranges?

For pH between: 7.2 - 7.8 is acceptable.
For Total Alkalinity between: 80 – 160 is acceptable

Sanitiser And PH Levels

It is important to test and adjust the sanitiser and pH levels of your spa on a frequent basis. These tests should be performed prior to each use of the spa. At a minimum it is recommended that you test the spa water 2-3 times a week, regardless of use.

Always test the pH level before you test the sanitiser level. If the pH level is not within the correct range (7.4-7.6),make the necessary adjustments.With each sanitiser test, use either granular Chlorine(Dichlor-type only) or granular Bromine to maintain the following levels:

Without Ozone
Chlorine Level 3.0-4.0 PPM
Bromine Level 2.0-4.0 PPM
Hydrogen Peroxide Level 80 – 100 PPM

With Ozone
Chlorine Level 1.0-3.0 PPM
Bromine Level 4.0-10.0 PPM
Hydrogen Peroxide Level 60-80 PPM

Changing Spa Water

As you use your spa, soap and detergent residues from your skin and bathing suits, along with other substances from maintaining the spa’s water chemistry will accumulate in the spa water and make maintaining the water more difficult.

How Can I maximise the Life of My Spa Water?

Rinsing your bathing suits, and showering without soap, prior to entering your spa will increase the life of your spa water. Depending upon usage, the spa water will need to be changed every 4-6 months or when the water chemical levels become difficult to manage.

When changing spa water, if your spa is fitted with JetPaks™. remove all JetPaks™. Clean the JetPod™ areas with a spa surface cleaner. See Spa Shell Care. Clean the plumbing areas on the back of the JetPaks with a spa surface cleaner and a long, soft bristle brush.

How do I Drain My Spa?

Step 1: Turn-off main electrical breaker to spa.

Step 2: Locate drain spout below equipment compartment door.

Step 3: Pull the drain spout out with a slight clockwise turn.
Note: Drain spout is fully extended at approximately 50mm. Use pliers if needed

Step 4: Remove drain cap.

Step 5: Attach a standard garden hose. Push the drain spout in halfway to actuate the drain.
Note: The Spa will drain about 20 litres per minute. Ensure that the drainage is in an area safely away from windowwells or basement entries.

Step 6: Once the spa is fully drained, pull the drain spout out all the way, remove hose, replace the drain cap and push drain in all the way.

How Do I Refill My Spa?

WARNING: When refilling the spa, always Super Sanitise the new water.

Step 1: To avoid air pockets in the pump(s), refill the spa with water by placing the hose into the filter compartment through the Weir door. Fill to the water level indication on the faceplate of the filter assembly.

Step 2:
Restore electrical power supply.

Step 3:
Press any button to reset the control system.

Step 4:
Following instructions in Starting the Spa with New Water.

IMPORTANT: Never fill the spa with soft water unless an appropriate mineral supplement is immediately added. If your water is extremely hard, it is preferable to either dilute the water’s hardness by blending the water with water from a water softener, or by the addition of a special water softening chemical. For more information, see your authorised Spa dealer.

NOTE:
The higher the water level in the spa, the fewer spa users it will be able to handle.

Starting The Spa With New Water

Never fill the spa with soft water unless an appropriate mineral supplement is immediately added. If your water is extremely hard, it is preferable to either dilute the water’s hardness by blending the water with water from a water softener, or by the addition of a special water softening chemical. For more information, contact your authorised Spa dealer.

Step 1: Add the prescribed dose of Stain and Scale Inhibitor while filling the spa. This will provide the initial protection against staining and scaling. Once the spa is filled, add the prescribed dose of Water Clarifier. This will clear the water of any micro-particulates that may be in the new water.

Step 2: If possible, have your authorised Spa dealer test the calcium hardness (CH) of your spa water. Adjust theCH to 150-200 parts per million (PPM).

Step 3: Test and adjust the Total Alkalinity (TA). TA should measure 100 to 120 PPM.

Step 4: Test and adjust the pH. Water pH should measure 7.4 to 7.6.

Step 5: After the spa water has circulated for 1 hour, Super Sanitise the water by adding 2 teaspoons (10cc) of Granular Chlorine (Dichlor-type only) or 4 teaspoons (20cc) of Granular Bromine per 200 gallons (909.2l) of spa water. (For complete details, refer to the Super Sanitation section.) After several hours, check sanitiser level and adjust, if necessary, to the following:

Step 6: Startup water chemistry is now complete. However, it may take several days for the filter to completely clear the water.

How Do I Test My Spa To Ensure It Is Ready To Use?

Correct water balance ensures that equipment and surfaces are protected and that water is comfortable for bathers. To test pH, alkalinity and calcium levels in the water, use the Spa Fresh 4 Way Test Strips.

Remove the strip from the vial and swirl beneath the surface of the spa water 2 to 3 times then line the strip up against the outside of the container.  (Do not shake water from the strip). ​​

Maintain alkalinity at 80 - 120 ppm and pH at 7.2 - 7.6. Using the label, determine the correct amount of Spa Fresh Alkalinity &pH Increaser required. Scoop up container of spa water and add the required dosage of Spa Fresh Alkalinity & pH Increaser. Dissolve  Spa Fresh Alkalinity & pH Increaser completely in the bucket & pour back into spa. Re-check pH & alkalinity using Test Strips. Repeat process if needed to attain correct level.

Water Quality Maintenance

Spas are the perfect way to unwind and relax in the comfort of your own home. A portable spa in your own backyard is a place to relax, spend time with family and friends, or soothe away aches and pains with a therapeutic massage.

Maintaining the quality of the spa water

Maintaining the quality of the spa water within specified limits will enhance your enjoyment of the spa and prolong the life of its equipment. It is a fairly simple task, but it requires regular maintaining because the water chemistry involved is a balance of several factors.

There is no simple formula and there is no avoiding it.

A careless attitude regarding water maintenance will result in poor and potentially unhealthy conditions for bathing and possible damage to your spa. For specific guidance on maintaining water quality, consult your authorised Spa dealer who can recommend appropriate chemical products for sanitising and maintaining your spa.

Sanitisation

Sanitisers kill bacteria and viruses and keep the water clean. A low sanitiser level will allow bacteria and viruses to grow quickly in the spa water. To raise the sanitiser level, simply add an approved sanitiser. A high sanitiser level can cause discomfort to eyes, lungs and skin. To lower the sanitiser level, simply wait – the sanitiser level will naturally drop over time. Effective and safe sanitisers include Granular Chlorine (Dichlor-type only), HydrogenPeroxide and Granular Bromine.

Super Sanitisation (Spa Shock)

Normal sanitation does not eliminate Chloramines (trapped Chlorine), Bromamines (trapped Bromine), along with other non-filterable wastes, such as perspiration, oils, hair sprays, etc. that can build up in the water. These substances make the water unattractive in appearance and odour, and can interfere with sanitiser effectiveness.

Super Sanitation is achieved by adding high levels of Spa Fresh Shock or equivalent which is a non-Chlorine shock(Potassium Peroxymonosulfate or equivalent). Contact your authorised Spa dealer for assistance.

When Super Sanitising your spa water, and providing that you are available to attend to the safety of any children present, you should allow the high level of oxidiser to off-gas by opening the spa cover at least half way for a minimum of 20 minutes. Failure to allow high concentrations of sanitiser to off-gas with the spa cover open will cause the underneath side of the cover to discolor and degrade. Such damage to the spa cover is not covered under the terms of your spa’s warranty.

pH Control (PH)

Proper pH balance is extremely important in providing water that is comfortable to the user, and preventing damage to the spa and equipment. The measure of acidity and basicity in the water is called pH. The pH scale ranges from 0-14. Levels of pH less than 7.0 are acidic while pH levels greater than 7.0 are basic. The proper pH range for a spa is 7.4-7.6. High pH levels (greater than 7.6) can cause scale build-up on the spa and its equipment, cloudy water, a prematurely dirty filter, and less effective sanitation. To correct high pH levels, add a pH decreaser. Low pH levels(less than 7.4): can cause discomfort to the spa users, rapid dissipation of sanitiser, and corrosion to the spa equipment. To increase pH levels, add a pH increaser.

Total Alkalinity (TA)

TA is the quantitative measurement of alkaline components (carbonates and bicarbonates) present in water, which ifproperly adjusted, act as a buffer against rapid pH changes. Proper total alkalinity levels are important to ensureoptimal chemical balance in spas. Low TA can cause the pH to be unstable causing the water to be corrosive or scaleforming to the spa and its equipment. To correct low TA, add a Total Alkalinity Increaser. High TA can cause scalebuild-up, cloudy water, as well as other pH problems. If the spa water has high TA, contact your authorised Spadealer for assistance.

Calcium Hardness (CH)

CH is the measure of dissolved calcium in the water. Low CH (soft water) can stain the spa surface as well as cause corrosion to the spa and its equipment. To correct low CH, add a CH Increaser. High CH (hard water) can cause cloudy water as well as rough scale build-up on the spa surface and equipment. If the spa water has high CH, it is preferable to either dilute the water’s hardness by blending the water with water from a water softener, or by the addition of a special water softening chemical (contact your authorised Spa dealer).

Stain and Scale Control

Stain and scale problems are common in hot water environments. To help prevent and control staining and scaling, add a Stain and Scale Inhibitor.

Foam Control

Spa water that is polluted with body oils and lotions, combined with high water temperatures, can cause excessive surface foaming. For a temporary fix, add a Foam Remover. The best way to control foam is to Super Sanitise the water; this will destroy the soap agents that normal levels of sanitiser will not.

Cloudy Water Prevention and Control

There are two basic reasons that spa water becomes cloudy. Non-filterable liquid waste (e.g. perspiration) has contaminated the water. To remove these substances, Super Sanitise the water. Or, non-filterable micro-particulate waste (e.g. dust) has contaminated the water. To remove these substances use a Water Clarifier.

Ozone purification

Ozone purification is recommended only as a supplement to the above sanitisers. Ozone Purifiers greatlyenhance the quality of the spa water when used in conjunction with an industry standard spa chemical maintenanceprogram.

Some General Questions We Get All the Time

Ozone purification is recommended only as a supplement to the above sanitisers. Ozone Purifiers greatlyenhance the quality of the spa water when used in conjunction with an industry standard spa chemical maintenanceprogram.

Why is my water cloudy?

Cloudy spa water can result from a heavy bather load.   It can also be a result of dirty filter cartridges, clean with Spa Fresh Filter Scrub as per instructions.  Other causes can be insufficient filtering time, pH and alkalinity out of balance or incorrect dose rate and low levels of calcium hardness (particularly with tank water).  Sometimes it is simply time to dump the spa water.​

How often do I need to drain the spa?

This depends on the bathing load of your spa. Heavy usage  6-8 weeks. Regular usage  8-12 weeks. Light usage   12-20 weeks.

This is a guideline only, but should be done at a maximum of 20 weeks or when the Total Dissolved Solids (TDS) level exceeds 1000ppm. For convenience use the Spa Fresh 4 Way test strips.

Why does my water have a bad odour?

Smelly spa water can be the result of insufficient dose rate of Sanitiser, pH and alkalinity being out of balance, heavy bathing load or dirty filter cartridges.  If all have been checked and are fine, it can be that the spa has been covered for a period of time and a condensation smell can appear. Remove cover and wipe down with damp cloth and Spa Fresh Pipe Degreaser (using rubber gloves) rinse off and leave in the sun to dry. The Spa Fresh range has no smell, where others contain a chemical odour which masks the cause of the smell.

Why do I have to use a Pipe Degreaser when I dump my spa water?

An accumulation of 'body fats' builds up on the internal wall cavities of the pipework of your spa.  These body fats will absorb sanitizers causing excessive usage of product.  This can lead to a breeding ground for bacteria.  You need to eliminate this from your system to prevent any build up.  Use Spa Fresh Pipe Degreaser as per instructions prior to every water dump.

How often do I need to clean my Filter cartridge?

Spa filters should be cleaned every 3-6 weeks, or as required.  This depends on bather usage and surrounding elements.  Regular cleaning of filters will ensure maximum filtration of spa water and will prolong the life of your filter.  Just hosing down the filter will not clean it.  The filter traps body fats which are an oily build up that water will not disperse.  Use Spa Fresh Filter Scrub to dissolve these body fats, then hose down with a garden hose.

Do I need to Balance my Spa Water?

This depends on water quality, water will differ from area to area around the country.  It is recommended that regular testing using Spa Fresh 4 Way Test Strips, will enable you to test and adjust if required. See 'Balancing the Water'.

My Spa has an Ozonator fitted, should I still use Sanitiser?

Ozone maintains a healthy environment for your spa, and kills bacteria that is external to the spas. However, the main body of water still needs to be sanitised to provide a healthy spa environment. Spa Fresh Spa Sanitiser is compatible with ozone.  Using Spa Fresh Spa Sanitiser in conjunction with ozone maintains a 'chlorine free' environment.  This also ensures that a registered bactericide is used within the spa water.

What should I do with my spa when I am away?

Portable spas may be emptied and left covered. An in-ground spa should be degreased, dumped and then upon return, follow start up directions. This is to be done if away for a lengthy period of time. If you are only going away for a few days or up to a week, test water to ensure balance is fine and add 500mls/1000litre of Spa Fresh Spa Sanitiser, and retest upon return. If going away for a long time, add a Start-up Dose of Spa Fresh on return (see Start-up instruction)

I have Algae in my spa - how do I get rid of it?

On occasions a spa will become infected with algae. This is more common with tank water, Should this occur we would recommend the following:Visit your local Spa retailer and purchase a packet of Spa Fresh Algicide.

​Make a premix with one half of the contents of each colour sachet in some water and when dissolved pour the blend into the spa. Try to have the pH at 6.8 -7 as this will assist the algicide to be more effective.​

Circulate and filter for 8-12 hours. (The spa will initially go cloudy however do not let that worry you), turn air jets on and off several times during this time. At the same time, using a damp cloth with Spa Fresh pipe degreaser on it, wipe inside of spa and around jets, under head rests and the underside of the spa cover. Rinse off the spa cover and leave exposed to the sun.

(If the infestation is severe and when the water is ready to be dumped, remove the filter cartridges, add Spa Fresh pipe degreaser and circulate for 30 minutes and then dump at this point)​Burn off dead algae with Spa Fresh Spa Shock at 60grams/1000 litres and filter for 4 hours, then clean filter cartridges, thoroughly rinse and flush the filter cartridges until water runs clear through the filter cartridges. If required, balance water with Spa Fresh Balance (alkalinity 120ppm, pH 7.6.)Finally, dose the spa with Spa Fresh Spa Sanitiser at the rate of 1 litre/1000 litres of water.

What is the purpose of a circulation pump?

A circulation pump maximises water filtration in your spa, with the greatest energy efficiency. The high movement and low wattage circulation pumps used in our range of spas has the highest 10 Star Energy efficiency rating and has been rated as the best performing filtration system in the industry.

How long does it take to heat the spa?

With the Hybrid Spa System option, you can have your spa heated and ready to use in under 30 minutes. With a spa’s standard heating system, the spa will heat 1,000 litres by 3 degrees per hour.

What is Ozone Sanitisation?

Ozone Sanitisation does not replace the need for chemicals but works to maintain clean, clear water and reduce the chemical load by 50-60% (dependant on use). The ozone generator runs and sanitises the water when the filtration pump is running. As Ozone is one of nature’s most powerful oxidizers for purifying water and other substances, it creates no dangerous by-products, corrosion or disposal issues. For these reasons, it is fast becoming the preferred eco-friendly method.

For these reasons, it is fast becoming the preferred eco-friendly method.

Ozonators work by forcing ozone to dissolve in the water, instantly neutralising or killing a wider range of contaminants. As with ozone from the protective layer of the atmosphere, ozone produced from the ozone generator oxidises the substances it encounters, including bacteria, viruses, algae, oils, human fluids, fungus, chlorine by-products like chloramines, and some metallic elements.

Ozone oxidises contaminants so rapidly that leaving nothing behind but ordinary oxygen (O2). For commercial pool disinfection, ozone is one of the two secondary sanitizers to be included in the Model Aquatic Health Code’s uniform guidelines for alternative pool sanitation. This inclusion may provide the endorsement ozone needs to move well past competing technologies among both residential and commercial customers.

What is UV Sanitisation?

 UV Sanitisation is a non-chemical process that uses germicidal UV light rays to sanitise the spas water. The highly concentrated electromagnetic energy also destroys organic matter found in spas, eliminating the formation of dangerous chlorine biproducts. To obtain the best results from a UV Sanitisation system, it is recommended that it be used along side an Ozone Sanitisation System.
