WATER TROUBLESHOOTING CHART: This chart is merely to familiarize you with problems and their possible causes.

PROBLEM	POSSIBLE CAUSES
Excessive chlorine (or its alternative) use	*Hot and humid weather with intense sun. *High bather load. *Low Cyanuric Acid level.
Algae	*Poor circulation and filtration. *Low Free Chlorine/alternative level. *Neglect of shocking. *Neglect of maintenance schedule. *Algae spores in the air-carried by wind.
Cloudy Water	*Poor circulation and filtration. *Low Free Chlorine/alternative level. *Neglect of shocking. *High pH, Alkalinity, or Hardness levels. *Early stages of Algae. *Microscopic particles suspended in water.
Corrosion of metallic parts (walls, floor, rails, ladders, light fixture, equipment).	*Low pH, Alkalinity, or Hardness levels. *Placing chemicals in the skimmer(s).
Cloudy Green water	*Low Free Chlorine/alternative level. *Neglect of shocking. *Early stages of algae.
Green, or Blue-green tint to the water	*Low pH, Alkalinity, or Hardness levels. *Copper in the water (heater-----?) *Use of a Metallic Algaecide.
Brownish-red tint to the water	*Low pH, Alkalinity, or Hardness levels. *Iron in the water (light fixture-----?)
Stains	*Failure to recognize colored water. *Ongoing low levels for pH, Alkalinity, or Hardness.
Scale	*High pH, Alkalinity, or Hardness levels.
Eye and Skin irritation (common with use of chlorine, but not with its alternatives).	*Low Free Chlorine level *Excessively high Free Chlorine level. *High or Low pH or Alkalinity levels.
Musty Odor (common with use of chlorine, but not with its alternatives).	*Low Free Chlorine level. *Presence of algae.
Water Line (Scum Ring)	*Suntan lotion, deodorant, or make-up *Body oils. *Dirt or other debris
Foam	*Ongoing presence of a water line. *Low Hardness level. *Use of a Quaternary Algaecide.
Excessive chemical use	*High Total Dissolved Solids reading.
Chemicals okay but water chemistry is still poor.	*Poor circulation and filtration. *Neglect of shocking. *Neglect of maintenance schedule.
