How To Test Copper In A Spa

Items Needed to test the copper.



*Test the pH first.  If it is above 7.2, adjust it to 6.68 - 7.0 before testing the copper.  If the pH is out of that range the copper test won't be accurate.

Copper Test Kit

1)  Make sure the plastic sample tube is clean and dry.  Take a sample of water from beneaththe surface of the spa water.

2)  Add 5 drops of Copper A to the sample, put the lid on the tube and turn the tube over to mix.

3)  Then, add 5 drops of Copper B to the sample and turn the tube over to mix. Wait exactly 3 minutes.

4)  To read the results you will look down through the length of the sample tube.  Hold the tube about 1" above the white section of the color chart. 

5)  Compare the color and record the results.  (It is important to look down through the length of the tube, and not through the side)

Tip:  Store test kits in a cool, dry place.  Do not store in heat, direct sunlight, or extreme cold.  It is recommended to replace test kits every year to ensure accuracy.
