The water in my swimming pool has a metallic blue effect, my hair turns green ... what can I do?

How can I recognise a copper oxidation problem?

Pool water has turned metallic blue, with a shimmering effect

A product or substance added to water contains copper sulphate
After swimming, hair has green highlights

Copper sulphates have a colouring action on light hair

If your problem does not correspond to these symptoms, it is possible that your pool is experiencing a similar problem.

Step by step

TO EFFECTIVELY COMBAT METALLIC BLUE WATER

1

Raise the pH to between 7.5 and 7.8

using pH-Plus. With a higher pH, copper removal will be easier with the flocculant. > pH-Plus
2

Add a flocculant

If you have a sand filter, place a cartridge of Superflock Plus in the skimmer to sequester the copper in the water.. > Superflock Plus
3

Filter twenty-four hours a day

Leave the filter running 24 hours a day until the problem is solved.
4

The water still not crystal clear?

After washing the filter, if the water is still not crystal clear, add another Superflock Plus cartridge in the skimmer. > Superflock Plus
5

Adjust the pH of the water

With pH-Minus or pH-Plus. Adjust the pH to between 7.0 and 7.4 if treating with chlorine. For bromine treatments, adjust the pH to between 7.4 and 7.6.. > pH Minus, pH Plus, Quicktest, Pooltester Electronic
6

Add an algaecide

that does not contain copper sulphate such as Desalgin^®JET > Desalgin^®JET
7

Filter twenty-four hours a day

Until the water is crystal clear again, then resume your normal daily filtration routine.
