|Cloudy water||Excessive organic contaminants or lack of sanitizer||Shock treat with non-chlorine shock
and adjust sanitizer level
|Dissolved chemical solids||Use clarifier to help remove small
|pH balance or total alkalinity is incorrect||Test total alkalinity and pH. Correct
with pH increaser or pH decreaser.
|Calcium too high (hard water)||Use a sequestering agent weekly. Replace some water with softer water.|
|Dirty filter||Clean filter with filter cartridge cleaner.|
|Mineral deposits in water||Use a sequestering agent. Check water balance and adjust as necessary.|
|Clear green water||High iron or copper content||Use a sequestering agent|
|Cloudy green water||Low alkalinity level||Use pH increaser|
|low sanitizer level||Test sanitizer level, shock with
|Brown water||High iron or manganese level||Use a sequestering agent|
|Chlorine odor||Chloramines (combined chlorine level) is high.||Shock with non-chlorine shock|
|Eye/skin irritation||Organic contaminants, chloramines, or pH out of balance||Shock with non-chlorine shock.
Test and adjust pH level.
|Foaming||High concentration of chemicals due to evaporation and build-up of body oils, cosmetics and other contaminants||Use foam reducer. Shock treat with non-chlorine shock. Use enzyme reducer weekly as part of regular maintenance|
|Pitting of metal fixtures||pH too low||Test and adjust pH and total
alkalinity by adding pH up.
|Total alkalinity too low|
