Chloramines

Swimmer waste, oils and organic waste

Shock Treatment

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 (total alkalinity)pH and/or CH (calcium hardness)

Metal Out or Stain Out

Balance water

Acid wash

Etching

Pitting of plaster surfaces

Improper water balance – low TA (total alkalinity)pH and/or CH (calcium hardness)

Balance water

Replace the plaster surface

Liner wrinkling

Wrinkles in a vinyl liner

Improper water balance – low TA (total alkalinity)pH and/or CH (calcium hardness)

Balance water

Replace the liner if necessary

Bleaching

Pale to white, spotty discoloration on the surface

Improper chemical addition

Replace the liner if necessary

Repaint the surface

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)

Metal Out or Stain Out

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

Use Algaecide

Green Hair

Blonde hair turns green after swimming

Copper

Metal Out

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 than1/2” 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
