How To Test Copper In A Pool
Items needed to test copper in a pool:
Test the pH. If it is above 7.2, adjust it to 6.8 - 7.2 before testing the copper. If the pH is out of that range the copper test won't be accurate.
1) Make sure the plastic sample tube is clean and dry. Take a sample of water about 18" below the surface of the water - and away the return jets and skimmers
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.
