High Copper Level

Last modified: March 21, 2018 @ 5:02 pm


Copper in the water can cause a number of problems, especially at higher residuals and if it is not chelated. Copper does have algaestatic properties, and used properly, such as with copper-based algicides like Banish, can be a great help in ridding the pool of resistant algae types. However, if the copper is not properly chelated, it can cause some or all of the following problems:

Discolored Water: Water that is clear with a green or turquoise cast.

Staining: Copper can stain pool surfaces green, turquoise, grey or black.

Consumption of SoftSwim C and B: SoftSwim C and B react with metals and the presence of metals can deplete these levels, clouding the water and allowing bacterial and algae growth to get a foothold.

Metals can enter the water through a number of sources, such as copper-based algicides that are not chelated, metal in the fill water, and metal from equipment corrosion.

Copper Stain Removal

Copper can stain pool walls and bottom turquoise, green, grey, or black. The stains do not brush up easily.

Removing Copper from the Water:

Special note for Bromine Pools: If you are using bromine, check the water balance first. Brominated water will sometimes take on a yellow or green cast if the water becomes too acidic. Increasing the Total Alkalinity and/or pH usually takes care of the problem.

Chlorine/Bromine Pools:

  1. Add 1 qt. of Pool Magnet Plus per 10,000 gallons for each ppm metal. (Do not exceed 3 qts. per 10,000 gallons.) Pool Magnet Plus chelates the metal so that it does not stain the surface or discolor the water.
  2. Leave the pump running continuously for 48 hours.
  3. Apply Sparkle Up to the filter according to the filter type and size. Circulate for 24 hours. Sparkle Up helps the filter remove chelated metal from the water.
  4. After 24 hours, remove the Sparkle Up by backwashing or rinsing the grids or cartridge.
  5. Clean the filter with Kleen It according to label instructions to remove any residual metal from the filter.

SoftSwim Pools:

  1. Add 1 qt. of SoftSwim Stain Control per 10,000 gallons for every 2 ppm metals. Circulate for 48 hours.
  2. Add SoftSwim Filter Aid and Flocculent as a Filter Aid to help the filter remove chelated metals. Circulate for 24 hours.
  3. After 24 hours, remove the SoftSwim Filter Aid and Flocculent from the filter by backwashing or rinsing grids and cartridges.
  4. Clean the filter with SoftSwim Filter Cleaner to remove any residual metals from the filter.

Green hair, nails and swimsuits

Copper can sometimes cause hair, nails and swimsuits to turn green. To remove this green tint from hair, rinse in lemon juice, 1 part vinegar to 4 parts water, or use a shampoo available at most drug stores called “Ultraswim”.
