M.) Quick Chart Model SPA-1R
1.) Maintain Water Chemistry as Normal
Keep pH between 7.2 and 7.6 This is very important!
Never allow the pH to get
above 7.8, as the copper and silver
ions fall out of solution and the water will get cloudy. If possible, keep the pH on the lower end of the scale. If the pH is too
high, use an acid demand test with your regular test kit to determine the amount of dry or muriatic acid needed to lower the
pH down to 7.2. If the pH is too low, use a base demand test to determine the amount of soda ash needed to raise the pH to
7.2.
– Test at least once a week or after heavy usage of the spa/hot tub or a heavy rain –
Keep Total Alkalinity between 80-120 ppm
Using a normal Total Alkalinity tester, determine the reading and adjust.
If the reading is below 80ppm, add the proper amount of sodium bicarbonate (baking soda). If the reading is above
120ppm, lower it by adding the proper amount of muriatic acid.
– Test at least once a month –
2.) Maintain Ion level between .15 and .20 ppm
Follow directions located inside the “Ion Test Kit” that is included with the
SPA-1R
to determine the ion level in your spa/hot tub. If the reading is too high, lower the
SPA-1R
ionizer output level by
turning the control knob counter-clockwise. Wait a few hours before testing again. If the reading is too low, raise the
SPA-
1R
ionizer output level by turning the control knob clockwise. Always keep the Ion Test Kit indoors and out of direct
sunlight.
– Test once a week –
Test Kit Reordering Information:
Replacement Ion Test Kit - Part # CLA-41
- Includes new complete test kit as supplied with
SPA-1R
.
Replacement Reagents - Part # CLA-42
- Includes new reagent bottles of “A” and “B” only.
3.) Add an Occasional Oxidizer
An occasional oxidizer is necessary to burn off body oils, suntan lotions, and particles that get
into the water and can cause cloudiness. Always add an oxidizer whenever the water loses its “sparkle”. Don't wait for the
water to get cloudy, or an extra dose will be required.
There are several oxidizer options:
Non-chlorine shock
- Add one (1) ounce of potassium monopersulfate (non-chlorine shock) per 300 gallons once a
week during the warm weather season, less frequently during the cooler weather, or when the water loses its “sparkle”. You
may also want to add some non-chlorine shock after a rainstorm if the spa/hot tub was left uncovered. These are available
in most spa/pool stores, or at
Leslie's Swimming Pool Supplies
(1-800-537-5437) and ask for “
Fresh 'N Clear
”.
Household bleach
- Add two (2) ounces of regular household bleach per 300 gallons once a week. You may also use
liquid chlorine – but only ½ the amount. This small amount will dissolve rapidly and you will have chlorine-free water in a
few minutes.
Add ozone to your system
- By adding the
Clearwater Pool Systems’ OZ-SPA
, you will be able to lower your
chlorine/bromine use even more dramatically! You still may need to add an occasional oxidizer, but with a less amount and
frequency.
4.) Maintain Normal Spa/Hot Tub Maintenance
Always maintain the spa/hot tub like you normally would. Keep the filter
cleaned and backwash on a regular basis. Empty the skimmer and strainer baskets as needed and keep the spa/hot tub
vacuumed. Good circulation is extremely important especially since you are no longer using a lot of chlorine/bromine to
keep the water clear.
5.) Add a Sequestering Agent for Marcite/Gunite Spa/Hot Tub
If your spa/hot tub is made of a white marcite or gunite
finish, we strongly recommend you add a sequestering agent to prevent any type of staining in the spa/hot tub. There are
two types we recommend:
-
Pool Stain Treat
by
United Chemical
(800) 524-5550
-
The Ionizer Stuff
by
Jacks Magic
(800) 348-1656
These products or ones similar are available in all spa/pool stores worldwide. If using another brand,
ensure it does not work by removing copper from the water!
6.) Cleaning and/or Replacing the Electrodes
- The only part of the
MineralPURE SPA-1R
that will need maintenance or
replacement is the electrodes. They should last 10 years depending on your spa/hot tub size, length of swimming season,
water temperature and how well the water was balanced (ion level, pH, etc.). To inspect the electrodes, simply unscrew the
electrode chamber with your hands and visually inspect the electrode bars. A blue greenish coating is normal, however, if
there is a heavy build-up, you may need to clean the electrode. Using an old toothbrush and lemon juice or a muriatic
acid/water solution, scrub the build-up off the electrode. If the electrodes are thin and worn out, they will need to be
replaced.
