TechniChlor and ColorChlor manuals recommend a salt level of close to 3,000 ppm. The amount of salt required will depend greatly on the size of you tub in gallons. Most applications will require about 5 pounds, but please refer to the users guide instructions for the specific amount of salt for your particular tub.

These are simplified equations here.

• Cups of Salt = Spa Gallons * (3000 – Current Concentration) / 81,000
• Pounds of Salt = Spa Gallons * (3000 – Current Concentration) / 120,000

The current concentration can be found using the included test strips. It will take your tub some time to dissolve all the added salt. If the water is hot this should take 30 minutes to an hour. if the water is cold, it may take overnight.

It is always recommended you start the conversion to salt water chlorine generation with a complete flush, rinse and cleaning of your tub or spa to remove any contaminates and residual.

While your TechniChlor or ColorChlor is oxidizing bacteria and other reductants, the chlorine reverts back to chloride ions to maintain the salt concentration in the pool. Top-off salt needs to be added when fresh water is added to the pool due to water losses from splash out, pump outs or filter backwashing. In northern climates, pools are usually drained and “winterized” at the end of the swimming season and new salt is necessary when the pool is re-filled the following spring.

If your tub is used year-round, it is also recommended to drain and refill every six months.

Chlorine Generators are changing how Americans, Canadians and Europeans are managing their hot tubs and spas.  The technology was first implemented in Australia years back, but has now come to this side of the world.

Salt water Chlorine Generators are the natural way to keep your hot tub or spa water sparkling clear, fragrant  and fresh.  Spa owners are turning to this natural way to keep their tub clean and healthy,  rather than continually dumping harmful chemicals into the water.

How a salt water chlorinator works

The first component is, of course, salt. Instead of the hash chemicals, you put a small amount of salt in the water - less than the salinity of your tears. The salt, dissolved completely in the water, is made up of sodium and chlorine.

The chlorine generator contains a series of plates with opposing electrical charges.  These charges start a very small chemical reaction called electrolysis which releases chlorine from the salt.  This is the most pure form of chlorine and since it is already in the flowing water, there is never any residue or by-products.

Note: Saltwater from the ocean has approx 20,000ppm (parts per million) of salt. Saltwater chlorinators require around 3000ppm, which generally can’t even be tasted.
