- High pH
- High total alkalinity
- Dirty Filter
|Test alkali content and adjust.
Shock pool (read label directions).
Adjust pH (7.2-7.6).
(New water when chemically treated turns blue, brown or black)
- Chlorine turned unseen copper, iron, or
manganese in water into visible compounds
- Circulatory system has water velocity too
|Adjust pH (7.2-7.6).
Run filter for 48 hours--backwash as needed.
Check circulatory system for high velocity to make sure
copper is not leached out of lines.
(Water in filled pool discolors)
- Leaves and debris in water
|Clean pool of leaves and debris.
Adjust pH, and alkali content.
Brush wall of pool.
Filter until clear.
- Floating algae or clinging to pool sides.
When chlorine drops to normal level, add algaecide as
Vacuum pool next day.
(Blue-Green spots adhering to pool surface-Chlorine resistant) or Mustard (Yellow powdery deposits on shady side of
pool- Chlorine resistant)
- Low Free Chlorine Level
- Pool chemicals unbalanced
|Brush spots with a stiff brush. Spot
treat the spots with chlorine tablets carefully (not on vinyl lined
pools) and shut off pump. Then pour concentrated all purpose algaecide
on spot. Leave dissolved algaecide in contact overnight. Next day start
water circulation, brush dead algae and vacuum to waste. If necessary,
repeat treatment. After vacuuming adjust pH. Keep chlorine level
adjusted to prevent reoccurrence.
