1. Copper Ion Test: Using the included copper test kit, ensure ions

are between 0.2 - 0.6 ppm; Test the ion level once a week until you

have found the proper Ion/Action setting for your spa. Increase

or decrease the Ion/Action setting as required. Carefully read and

follow the instructions for your copper test kit. Check the expiry date

of the copper test kit as test results may be inaccurate if used after

that date.

2. Mineral Cell: The mineral cell that delivers minerals to the water

must be checked every 6 months and will last roughly 2 years

under normal use conditions. You can purchase additional cells

from your authorized dealer. To replace your cell, simply turn old

cell counterclockwise to release it from the tee. Use your hand to

turn the cell clockwise into the tee until it is secure. To ensure even

wearing of electrodes, turn until the two prongs are oriented such

that water flows between them.

3. You will need to oxidize the water to break down excess organic

matter (i.e. sweat, urine, makeup, suntan oils). Chlorine or bromine

tablets are recommended over liquid shock as they are extremely

stable and slow releasing. You may prefer a non-chlorine oxidizer

such as Spaboss Energize (or equivalent brand) which is pH neutral.

Your spa may be equipped with an Ozone generator which is also an

effective oxidizer.

4. Keep the total alkalinity between 80 and 120 ppm.

5. Keep pH between 7.2 -7.8.

6. Keep calcium hardness between 200 and 300 ppm.

7. Keep total dissolved solids (TDS) between 500 and 2,000 ppm.

8. Ensure phosphates are at 100ppb or less by testing phosphates

on an algae free spa (chlorine must be below 5ppm). If phosphates

are above 100ppb use PHOSfree or similar product to remove the

phosphates. Once the phosphates are below 100ppb, maintain

with Pool Perfect+PHOSfree or similar. If phosphate levels continue

to rise, the following may be the cause: fertilizers, organics, metal

sequestering products, scale products, or extreme rainfall. The

above will cause phosphates to continue to rise above what Pool
