Conditioning and Stabilising the Water in your New Pool

Words by Niveau

Please note: The Hydrochloric Acid is to be diluted for your swimming pool. Use a 20L drum and fill with 15L of water then add 5L of Acid.

Balancing The Water
At the start of every season you will need to balance your pool water. The best way to do this is to take a sample of water to the pool shop and ask for an analysis. They will then inform you on what your pool requires and provide you with the appropriate chemicals if required.

It is also a good idea to repeat this process every time you require more chemicals. Then you will insure accurate chemical levels.

pH gives an indication of acid or alkaline the pool water is. The pH of the water must be maintained be between 7.2 and 7.8 the ideal being between 7.4 and 7.6. This is necessary to allow the chlorine to work effectively.

Incorrect pH levels can give any or all of the following results:

pH BELOW 7.2 causes

  • Eye irritation
  • Strong odours
  • Corrosion
  • Cloudy water

Use “Poolmaster” pH Plus to raise the pH.

pH ABOVE 7.6 causes

  • Eye irritation
  • Cloudy water
  • Permits rapid growth of algae
  • Reduced effectiveness of the chlorine
  • Scale and calcium deposits

Shock Dosing
This should be done 2 or 3 times a season. Add 5 litres of liquid chlorine and run the pool pump for 24 hours. Also leave the pool cover off your pool during this time. This should kill any bacteria or algae that might resist normal chlorine applications, and help clarify the pool water.

How to Dose with Chemicals

  • Add chemicals as near the water surface and close to the return inlets as possible to obtain the best and most even distribution.
  • Never add acid close to a skimmer or ladder, or any equipment containing metal.
  • Never add acid (pH minus) and chlorine to the pool at the same time, as the combination of the two can produce a poisonous gas. A good safety precaution is to add chlorine at night and acid in the morning.

Proper safe use of chemicals

Use goggles and protective gloves when handling chemicals.
Keep all chemicals out of the reach of children and in sealed containers.

Never mix pool chemicals together in the same container. The combination of certain chemicals can produce a poisonous gas or can even cause an explosion.

Always dose pool in accordance with manufacturers instructions as indicated on chemical containers.

Do not store chemicals in an unventilated room or plant room.

Always read the instructions on the chemical container labels before using the contents and follow them carefully.

Wash your hands thoroughly after using any chemicals.

Problems caused by a chemical imbalance and the solutions (please consult with the pool shop analyst for help).
Excessive chlorine usage: Pool water not stabilized and/or ph out of adjustment.
Solution: Add stabiliser/conditioner – correct ph level.

Eye & skin irritation: PH of balance, or combined chlorine level too high.

Strong chlorine odour:
Solution: correct ph. Test for combined chlorine and if too high dilute pool water from Mains as necessary.

Cloudy water:
Solution: check ph and chlorine. Adjust ph and superchlorinate. Add “ relax” liquid clarifier. Run filtration continuously until the water clears.

Water turning green: PH too high and chlorine residual (free chlorine) too low.
Solution: reduce ph, superchlorinate and when clear add algaecide.
