| PROBLEM | | REASON | | SOLUTION |
| Bright green water | | Algae growth | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Shock chlorinate water with Chlorifix or Chloriklar [five times the regular dosage]. |
| Dark green water | | Rapid algae growth | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Shock chlorinate water with Chlorifix or Chloriklar [ten times the regular dosage]. |
| After filling the water is of dirty green colour | | Iron in water | | Adjust the water pH to its maximum value [pH 7.4] using pH Plus or pH Minus. Then turn on the filter for a few days and shock chlorinate water with Chlorifixem or Chloriklarem [fifty times the regular dose] until the water clarifies. Aid the clarification process with a liquid flocculant (e.g. Quickflock Super) adding it directly into the pool. |
| After filling the water is ink-coloured | | Manganese in water | | Adjust the water pH to its maximum value [pH 7.4] using pH Plus or pH Minus. Then turn on the filter for a few days and shock chlorinate water with Chlorifixem or Chloriklarem [fifty times the regular dose] until the water clarifies. Aid the clarification process with a liquid flocculant (e.g. Quickflock Super) adding it directly into the pool. |
| Brown water | | Excess of organic substance | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Clean with tampon or liquid Quickflock Super, then shock chlorinate with Chlorifix or Chloriklar [five times the regular dosage]. |
| Slimy floor and walls of the pool | | Algae starting to grow | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Shock chlorinate with Chlorifixem or Chloriklarem [five times the regular dosage]. |
| Local green spots (steps, corners) | | Local algae growth | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Chlorinate locally with Chlorifixem dissolving it precisely within the green spot or placing the chemical in a bag and hanging within the area. |
| Cloudy water | | Hard water containing solid particles | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Clean with tampon or liquid Quickflock Super. |
| Limescale | | Hard or very hard water | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Use Calcinex Pool to stabilise water hardness. |
| Scum line | | Grease layer on the water surface | | Clean the scum line with Bordnet. Place two Superflock sachets [1 for every 50m3 of water] in the skimmer. |
| Eye and nose irritation | | Very low pH or chlorine reaction | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Shock chlorinate with Chlorifix or Chloriklarem [five times the regular dosage]. |
| Unpleasant smell of chlorine | | Chlorine compounds decomposition | | Adjust the pH to 7.0 with the aid of pH Minus or pH Plus. Shock chlorinate with Chlorifix or Chloriklar [five times the regular dosage]. |
