Pristine Blue for Spas & Hot Tubs

PRISTINE BLUE

FREQUENTLY ASKED QUESTIONS

PristineBlue is a unique dual action bactericide and algaecide brought to the market as a completely chlorine and bromine-freealternative to traditional swimming pool and hot tub water disinfection systems. 

PristineBlue's active ingredient, Copper Sulphate. The bactericidal properties of copper have been known for centuries. It is one of the reasons why, in the UK, our houses have copper water pipes and copper hot water storage tanks. It is completely harmless to bathers and in fact it is so safe that it is often used as a drinking water additive in the USA!

What is PristineBlue?

PristineBlue is a completely different form of spa sanitiser to Chlorine or Bromine.  It sanitizes the spa water by destroying both algae and bacteria through the use of its unique copper based formula.

How does PristineBlue work?

The bactericidal properties of copper have been known for centuries. It is one of the reasons why, in the UK, our houses have copper water pipes and copper hot water storage tanks.  Some years ago, copper was tried in pools to control bacteria but this failed because the copper level could not be raised high enough to do the job without causing heavy staining to the pool equipment.  The technology has moved on significantly since then and by blending a unique proprietary base product (called ET3000) with copper salts, a biologically active structure is formed in which the copper ions are fully dissolved in the water.  The result is PristineBlue.

Once added to your spa water PristineBlue provides rapid, 100% disinfection by:

   Spreading rapidly throughout the spa water and pipe work.  (For the chemically minded, this is facilitated by the ions all being positively charged and so naturally repelling each other.)

   Killing the algae and bacteria on contact as they absorb the copper ions. (‘Debris’ from this action removed from the spa by the filtration system.)

This process continues until all the copper solution is used up.  Fortnightly ‘topping up’ of the PristineBlue to the required level keeps the disinfection process continuing safely.

What are the components of the Pristine Blue system?

PristineBlue is a complete ‘system' that comprises four essential and unique components that must be used together to convert and then keep your hot tub running with 100% safe and efficient disinfection.

The PristineBlue system comprises:

   PristineCheck - a hardness reducer to remove the calcium from your water before you start.

   PristineBlue - the copper based algae and bacteria inhibitor.

   PristinePower - a non-chlorine shock treatment to remove any non-filterable organic wastes.

   PristineClean - a scale formation and metal stain inhibitor

How is Pristine Blue supplied?

   PristineBlue comes in two forms:

   PristineBlue Starter Kit – everything you need to convert your spa to run on PristineBlue for up to 11 months of use!

Individual  bottled components to purchase as required

Can I use PristineBlue in any spa, old or new?

PristineBlue can be used in any spa, old or new, so long as it has an effective filtration system (removable/cleanable filters) and a means of providing water circulation through the filters for at least 4 hours a day.  We recommend the use of Spa Flush before you change to Pristine blue to remove  bio-film and calcium deposits from the plumbing and equipment without the use of harsh or toxic chemicals

Can I use PristineBlue in a spa with water that’s already got Chlorine or Bromine in it?

If the spa has just been filled with water and ‘shocked’ then you can switch to PristineBlue.  For a spa that has had Chlorine or Bromine in it for a week or more then you must drain the spa first and refill it with fresh water before using PristineBlue.

How do I start using use PristineBlue?

There are five easy steps to starting your tub on PristineBlue:

Step 1 – Drain your spa, clean and remove the hardness in your fresh water with PristineCheck

As with any sanitiser system you should make sure that your water is adequately balanced to protect your equipment and ensure that the water remains comfortable to bathe in.  When using PristineBlue the total alkalinity should be in the range 30 – 90 ppm and the pH should be in the range 7.0 – 7.4.   If your fresh water is outside this range you should use adjusters to first adjust the total alkalinity and then the pH.

PristineBlue works best when the calcium hardness of the fresh water in your spa is less than 250 ppm.  If the calcium hardness is above this level (as indeed it is in a lot of UK tap water) you then add PristineCheck at a rate of 25ml per 1000 litres of water.  Run your tub on the filtration cycle for 4 to 6 hours while PristineCheck sequesters the calcium out of the water and into the filter. 

[Note: With any disinfection system we recommend the use of Spa Flush at every water change to remove bio-film and other deposits from the plumbing and equipment without the use of harsh or toxic chemicals.]

Step 2 - Apply PristinePower non chlorine shock to remove any non-filterable organic wastes

Shock with 50g of PristinePower per 1000 litres of water and run the tub on the filtration cycle for a further hour to remove any non-filterable organic matter from the water.

Step 3 - Clean your filters

Step 4 – Apply an initial dose of PristineBlue  to stop the growth of algae and bacteria

The cornerstone of the PristineBlue system is the Pristine Blue liquid itself.  It is applied for control of algae and bacteria in initial and maintenance doses.  Add the initial does at a rate of 25 ml per 1000 litres of hot tub water.

Step 5 - Get in and enjoy yourself!

What regular water maintenance tasks do I have to perform?

With normal use you only need to maintain your tub once a fortnight.

Step 1 Check the water balance

Use a test kit to ensure that the total alkalinity is still within the range 30 – 90 ppm and the pH is in the range 7.0 - 7.4

Step 2- Test and maintain the PristineBlue concentration at the correct level

The PristineBlue concentration in the water must be maintained at 0.9 ppm, measured using the Copper Test Kit.  With normal use, it is only necessary to test the water once per fortnight since the liquid does not 'burn off', it stays in the water until it is used up by the demands of the tub.  The maintenance dose of PristineBlue liquid is likely to be between 2.5 ml and 25.0 ml per 1000 litres of hot tub water, depending on the size of your tub and the usage.

Step 3 – Apply the non-chlorine shock, PristinePower,  to remove non-filterable organic waste

Any non-filterable organic matter in your water may cause cloudiness.  In normal use add PristinePower to your water once per fortnight at the rate of 50g per 1000 litres of water.   Leave the water to circulate for 15 minutes before getting back into the tub.

Step 4– Apply the scale and metal stain inhibitor, PristineClean

The PristineBlue system includes a scale formation and metal stain inhibitor, PristineClean, which should be added at a rate of 15 ml per 1000 litres of water.

NB.It has become evident from the experience of some of our customers that when staring an older spa or converting from another sanitisation system, sometimes the first does of PristineBlue can be used up quite quickly, despite the water being properly in balance.  This may be due to biofilm in the pipework and filter.  Consequently we advise testing the copper level want water balance (pH, TA and Calcium Hardness) daily for the first week or so until the readings become stable.

Do I need to shock the spa water first?

Yes you should shock the water after you’ve filled the spa and removed the hardness from the water, and before using PristineBlue, using a non-chlorine shock. PristinePower, supplied in the starter kit, is best.  When using PristineBlue, you should also shock water fortnightly with PristinePower to destroy organic wastes, body fats and oils that the filter is unable to remove.  This will help to keep the water crystal clear and ensure that you use less of the PristineBlue liquid.

back to top

How often should I clean the filters in the spa?

Your filters should be cleaned every 2 to 4 weeks depending on use, as with any other sanitizer. The best way to clean the filters is usually in your dishwasher, on a 50oC wash cycle, with a proprietary filter cleaner poured into the soap dispenser.  If you don’t have a dishwasher then soak the filter(s) in water in a clean bucket with the filter cleaner and rinse off.  Always dry the filters first before reinserting them in the tub.

Howlong will PristineBlue last in my tub?

Each 250 ml bottle of PristineBlue lasts 4-11 months, depending on the size of your spa.  The table below shows how long one bottle will last in your hot tub.
