Trouble Shooter
The following table helps to solve problems with pool water
PROBLEM | POSSIBLE CAUSES | CHECK/REMEDY |
Algae Growth | Sunlight dissipating disinfectant |
Ensure disinfectant level adequate; Use
algicide |
Alkalinity High | Lower with an acid | |
Alkalinity Low | Raise with sodium bicarbonate | |
Brown Staining | Iron in water, corrosion of plant | Check water balance & adjust and/or Brown Water; Use flocculent and sequestrant |
Calcium Hardness Too High | Build up of hardness salts | Dilute the pool |
Calcium Hardness Too Low | Soft water supply | Raise to 200 mg/l and maintain with calcium chloride |
Chlorine too High Bleaching of DPD Tablet |
Over Chlorination Dosing system fault | Use Chlorine Reducer or Dilute Check dosing system |
Chlorine Too Low | Under Chlorination Dosing System Fault Direct Sunlight |
Check dosing system & for blocked chlorine
injectors Use algaecide if algae present |
Cloudy Water | Heavy bathing load; Inadequate disinfection; high cyanuric acid level; Problem with filters | Check disinfection & combined chlorine; Dilute pool as required; Check filters, backwash and use flocculant. |
Green Staining | Copper in water precipitating | Test for copper; Check water balance & adjust; Use flocculant & sequestrant. |
Green Water | Algae High Cyanuric Acid Level |
Check disinfectant level; use algaecide Check & dilute as required |
pH too Low | Acidic product being used |
Add pH plus (sodium carbonate) |
pH too High | Alkaline product being used Alkaline detergent cleaner used | Add acid (e.g. Sodium Bisulphate or Hydrochloric Acid) to reduce |
pH Unstable | Low alkalinity | Check & raise with Sodium Bicarbonate |
Salty Water | T.D.S. too high | Reduce by dilution |
Scale Formation | Water out of balance | Check and adjust |
