Step by step

TO EFFECTIVELY COMBAT AGAINST TRANSPARENT GREEN/BROWN WATER

Check the TAC

If the TAC is below 80 mg/L, increase it with Alca-Plus®. > Alca-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. With a balanced pH, treatment products are more effective.. > pH Minus, pH Plus, Pooltester Electronic,
Do a shock treatment
to neutralise all impurities and micro-organisms in the water.
- For pools treated with chlorine, use Chloryte_^®(non-stabilised chlorine), Chlorifix_^® or Chloriklar_^® (stabilised chlorine).
- For pools treated with bromine, use Aquabrome_^®
Add a flocculant

Place a cartridge of Superflock Plus flocculant in the skimmer basket every 7 to 15 days for pools with a sand or glass filter (if you have a cartridge filter, use Superklar) > Superflock Plus, Superklar
Filter twenty-four hours a day

Until the water is crystal clear again. then resume your normal daily filtering routine. If necessary, change the filter material (sand)
Backwash the sandfilter / clean the cartridge filter

Then reactivate the filtration system until the water is clear and colourless. If the water is still not crystal clear, put another Superflock Plus cartridge in the skimmer.
Prevent metallic deposits

To protect your pool, add Calcinex as soon as the pool is filled. You'll avoid new limescale deposits and metal stains or discoloration. > Calcinex_^®
