According to the suggestion of APSP, the adjustment should be continued as needed, and the interval between each
adjustment should be 24 hours until the free chlorine level in the pool water is stable at 1.0-4.0 ppm.
Precautions:
Don't fertilize your swimming pool. Fertilizer contains nitrate, which will lead to a high
demand for chlorine.
Never use dry acid to adjust pH value in arid areas, where evaporation is excessive and fresh
water rarely dilutes pool water. The accumulation of by-products will damage CMARCIC.
Do not add any pool water balancing chemicals (including salt) unless CMARCIC is turned off.
Do not let the cyanuric acid content in the outdoor swimming pool drop below 30 ppm.
Note:
DO NOT USE CYANURIC ACID IN INDOOR POOLS.
Maintenance
Every salt system requires maintenance after use, which is the focus of this section.
Weekly Service
PH level test: 7.4 to 7.6, although 7.2 to 7.8 is an acceptable range under the APSP guidelines.
Note:
Never use dry acid (Sodium bisulfate) to adjust pH value in arid areas, where evaporation is excessive and
fresh water rarely dilutes pool water. The accumulation of by-products will damage CMARCIC.
Total Alkalinity Test:
Use a reliable test method to test the total alkalinity of the pool water. Adjust according to the
advice of swimming pool professionals. The ideal range of total alkalinity is 80-100 ppm.
Chlorine Test:
Use a reliable test method to test the free chlorine of the pool water. Maintain the ideal range by
adjusting the CMARCIC cell sanitize output setting. Free chlorine needed: 1.0-4.0.
Note:
Chlorine exceeding 4.0 ppm may cause excessive corrosion of metal parts and may damage related swimming
pool equipment.
Monthly Service
To ensure that your swimming pool maintains the correct chemical balance, it is very important to perform the
following recommended salt and pool water tests every month with reliable test methods.
Adjust salinity according to LED warning and LED display.
Test salinity:
Press the salinity key to check the reading or take the pool water samples to the local pool
shop for testing.
Cyanuric Acid:
The pool water is sampled, and the content of cyanuric acid is detected by reliable detection
method. When CMARCIC is used, the recommended ideal cyanuric acid level is 30-50 ppm.
Calcium Hardness:
Use a reliable test method to test the calcium hardness of the pool water. Adjust
according to the advice of swimming pool professionals if necessary. The ideal range of pool water calcium is
200-400 ppm recommended by APSP.
Metals Detection:
It is recommended to regularly sample the pool water to detect whether there are metals
such as copper, iron, and manganese. These metals can damage batteries and other related swimming pool
equipment, so they should not appear in swimming pool water. If these metals are present, please contact
your pool professional.
TDS (Total Dissolved Solids):
Use a test kit or let a pool professional test the water sample to test the TDS
level of the pool water. Adjust according to the advice of swimming pool professionals if necessary. It is
