Rust-stained water

Caused by: - The corrosion of ferrous parts of the circulation system by low pH water

Cure: -

  • Act swiftly to prevent further damage - such as staining of the plaster, grout or liner
  • Check with your Pool Shop to see if it is safe to empty the pool and replace the water all in one go, or if should be done by progressive dilution
  • Remove rust stains from the pool surfaces with a proprietary tile or liner cleaner
  • Use PVC fittings to replace the ferrous metal fittings
  • Balance the fresh water as you refill your pool

Green Cloudy Water

Cause - low or ineffective chlorine levels, or urine in the pool (which strips chlorine from the water) have allowed green algae to flourish. Rectify this problem as soon as possible to prevent expensive repairs to the pool surfaces and filter

Cure: -

  • Superchlorinate to 10ppm (25ppm for more serious problems) and leave the pump running for 24 hours to kill the algae
  • Brush all surfaces to dislodge algae and to improve the circulation of the superchlorinated water
  • Any water haze can be removed with flocculant or Jolly Gel
  • If your pool is susceptible to algae use an algaecide monthly

Cloudy, Milky Water

There are four possibilities - your test kit will help you to decide which the culprit is

1st possibility - suspended particles give a milky white discolouration

This is likely to be caused by precipitation of dissolved minerals as a result of high pH

Cure: - Reduce the pH

To lower pH by 0.2 add Hydrochloric Acid at a rate of 1 litre per 50 m³ of pool water

Run the pump for 4 hours after dosing then test again

Repeat until correct reading is reached

 

2nd possibility - dirt or bather pollution build up due to low chlorine or poor filtration

Cure: - backwash the filter, Superchlorinate to 10ppm and then Flocculate

 

3rd possibility - the levels of stabiliser (cyanuric acid) are too high. The chlorine takes longer to kill organisms, which can then proliferate and lead to haziness in the water

Cure: - Replace some of the pool water by draining to waste (or carry out an extra-long backwash), top up with fresh water, then Superchlorinate to 10ppm

 

4th possibility - ineffective filtration

Cure: - Check clean the filter and check the filter media in a sand-filter; replace if necessary

Change the sand-filter contents every 4 years (or every 7 years if using Zeolite)
