Chlorine Demand Unable to maintain the free chlorine level or cannot break the high combined chlorine Foreign environmental contaminants

Poor maintenance

Shock treatment
Cloudy Water Hazy or extremely cloudy water

Difficulty seeing the pool bottom

Poor filtration and circulation

Chloramines or low sanitizer

Poor water balance

Particulate matter

Check the pump and filter

Clean and run the pump continuously

Surface Problems
Scale build up Sandpaper-like buildup on the surface

Grayish or tan coloration that is difficult to brush away

Improper water balance – high TA pH and/or CH Stain and scale preventer

Balance water

Acid wash

Etching Pitting of plaster surfaces Improper water balance – low TA, pH and/or CH Balance water

Replace the plaster surface

Liner wrinkling Wrinkles in a vinyl liner Improper water balance – low TA, pH and/or CH Balance water

Replace the liner if necessary

Bleaching Pale to white, spotty discoloration on the surface Improper chemical addition Replace the liner if necessary

Predissolve dry substances before addition

Staining Black, green, turquoise or brown spots on the bottom that do not brush up Metal stains

Fungus under the liner

Tannic acid

Stains (leaves and debris)

Stain and scale preventer

Pull up the liner and clean from the underside

Shock the pool

Testing Problems
Reagent Bleaching Color of test fades to clear High chlorine or bromine levels Add up to 5 drops of a chlorine neutralizer
Reagent Discoloration Reagent color is different than it should be – for example, the pH test turns purple or the DPD turns brown. High chlorine or bromine levels

Old reagents

Let the chlorine levels come down, then retest

Replace reagents

Other Problems
Foaming Bubbles on the pool surface Excessive algaecide

Foreign substance

Defoamer

Determine the source and partially drain if necessary

Add algaecide

Green Hair Blonde hair turns green after swimming Copper Stain and scale preventer

Lemon juice or vinegar in the hair to remove the color

Rain Rain washes debris into the pool and raises the water level, increasing the sanitizer demand Environmental Rebalance the water after circulating for 24 hours

Shock the pool

Water Loss Noticeable difference in water level Less than 1/2” daily – evaporation

1/2” to 1” daily – active bather load

Over 1” daily – possible leak

Solar cover for the first two levels of water loss

Professional assistance for anything over 1” daily
