PROBLEM SOLVING CHART
Symptom
Cause
Remedy
Green water/cloudy water
Inadequate sanitiser. Algae may
be present
Shock dose with Rotospa
Granular Shock or Rotospa Non-
Chlorine Shock
Too much chlorine
Overdose
Allow time to naturally dissipate
or buy a chlorine reducer
pH Hard to control
Alkalinity low
Use
Rotospa Scale inhibitor to
raise alkalinity
Cannot maintain chlorine levels
Chlorine demand of water too
high at start up, after holidays or
due to excessive contamination
or neglect.
Shock dose with Rotospa
Granular shock or Rotospa Non-
Chlorine Shock. Or use a double
dose of Rotospa Stabilised
Chlorine Granules/Rotospa
Bromine Granules
Foaming water
Oils/detergents present
Clean cartridges or consider if
time to drain and refill. Retest
water and add chemicals if
necessary.
Rough spa
sides/edges
Scale formation
Ensure pH levels are correct and if
scale persists use Rotospa
ScaleAway to stop calcium
precipitating out of water
No colour change during test
procedure
Chlorine level too high bleaching
indicators (Over 15 ppm chlorine)
Check expiry date on test tablets.
Wait for chlorine level to drop
and retest.
Test results vary
Air bubbles can increase pH
temporarily and reduce alkalinity
Test when system turned off for
true results
