PROBLEM
|
POSSIBLE CAUSE
|
Chlorine Residual
Low or Nil
|
• Insufficient
running times
• pH too high or low
• Strong sunlight and low conditioner levels
• Poor circulation
• Heavy bather loading
• Low chlorine production
|
Chlorine Production
Low or Nil |
• Low salt levels
• Scale build up on the cell
• Faulty circulation
• Algacide addition within the last 2 to 3 weeks
• Cell leads incorrectly connected
• Debris levels in the pool too high
• Cell too old and worn out
|
Chlorine Levels High in
Mornings and low at Night |
• Heavy bather loadings
• Extreme sunlight conditions
• Insufficient pool conditioner levels
|
pH Alters Rapidly and Easily |
• A low total alkalinity level in Marblesheen, pebble or tiled
pools
• Contamination with debris especially urine could be another
cause
|
Poor Circulation |
• Dirty and clogged filter
• Hair and link baskets full of leaves at the skimmer boxes
or pump
• Faulty pump
• Water level is low or cell is clogged with scale
|
Short Intervals Between
Backwashes |
• Ineffective backwashing
• Body fat or oil build-up on pads. With Diatomaceous earth
filters the cause may be insufficient diatomaceous earth over the
pads
|
| Cloudy Water |
• Insufficient filtration
times
• Holes in the filter pads
• High pH
• Pool walls need brushing
• Main drain not working
• Algacides have been added in the last few weeks, or
• Bather load too great for filtration and chlorine times
|
| Low Salt Level |
• The result of splash out
by bathers
• Heavy overflow from rain or accidental filling of the pool
• Topping up because of pool leaks or from excessive backwashing
|
| Appearance of Stains |
• Low chlorine levels
• High pH levels
• Poor circulation
• Infrequent brushing of the pool walls
• Incorrect total alkalinity
|
| Algae Formation and High Chlorine Levels |
• The pH is over 7,4 or
• The pool conditioner level is too high
|
| Frequent Cell Cleaning |
• Hard bore waters being
used
• Incorrect total alkalinity levels in marblesheen, pebble
or tiled or heated pools
• pH levels may also be too high
• Prior to the CHLORINATOR and currently, are you still adding
powered chlorine?
