Step by step

TO EFFECTIVELY COMBAT METALLIC BLUE WATER

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
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
Filter twenty-four hours a day

Leave the filter running 24 hours a day until the problem is solved.
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
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
Add an algaecide

that does not contain copper sulphate such as Desalgin®JET > Desalgin®JET
Filter twenty-four hours a day

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