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

  2. 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 MinuspH PlusPooltester Electronic,

    • Do a shock treatment

      • For pools treated with bromine, use Aquabrome®

      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 PlusSuperklar

      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
