Eau-colorée

The water in my pool is clear but has a green/brown tint... what can I do?

How can I recognise an iron oxidation problem?
  • The pool water turned colored after adding disinfectant.

    It turned green or brown

  • The water used to fill the system comes partly from a borehole

    The iron present in the water oxidized after a disinfectant was added.

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

Actions to effectively combat green/brown water

  1. 1

    Check the TAC

    If the TAC is below 80 mg/L, increase it with Alca-Plus®. > Alca-Plus®

  2. 2

    Adjust the pH of the water

    with pH-Minus or pH-Plus. Adjust the pH to between 7.0 and 7.4 if you are treating with chlorine. For bromine treatments, adjust the pH to between 7.4 and 7.6. With a balanced pH, treatment products are more effective. > pH Minus, pH Plus, Quicktest, Pooltester Electronic, Pooltester pH/Cl

  3. 3

    Perform a shock treatment

    to neutralize all impurities and microorganisms present in the water.

  4. 4

    Add a flocculant

    Place one Superflock Plus flocculant cartridge in the skimmer basket every 7 to 15 days for pools equipped with a sand or glass filter (if you have a cartridge filter, use Superklar). > Superflock Plus, Superklar

  5. 5

    Filter 24/7

    until the water is crystal clear again. Then resume your normal daily filtration routine. If necessary, replace the filter material (sand, Eco Filterglass Plus, or AFM). > Eco Filterglass Plus, AFM

  6. 6

    Wash the filter

    Then restart the filtration system until the water is clear and transparent. If the water is still not crystal clear, replace the Superflock Plus cartridge in the skimmer.

  7. 7

    Prevent metal deposits

    To protect your pool, add Calcinex as soon as you fill it. This will prevent new limescale deposits and stains or discoloration caused by metals. > Calcinex®
