The most accurate way to test for copper is by using the Copper Test Kit provided with your Naked System.
Recommended Copper Levels are 0.2-0.5ppm.
It is a simple test that takes just a few minutes and we recommend making it a part of your weekly/fortnightly routine.
When testing your copper level please ensure the pH is within range and read the sample in the shade and not in direct sunlight.
If you have your water tested by a pool shop and your copper level appears out of range, please use the Naked Copper Test Kit provided to compare to the shops results, before making adjustments to the copper levels.
If they are the same results, fantastic, if they are different, always trust the Naked Copper Test Kit.
Unfortunately we do come across instances where the 'machines' at pool shops incorrectly read copper levels.
