How To Test:

Please follow the instructions of your pool water test strips or test kit and enter the readings on the next screen. Make sure that your test strips or reagents have not expired. Reorder from the link below if needed.

Is your pool water cloudy?

Is there any visible algae present?

Cloudy: 100 ppm

What causes Cloudiness in pool water?

Cloudy water usually indicates unbalanced water and/or poor filtration.

Algae: 100 ppm

What causes Algae in pool water?

Algae growth is caused by a combination of high nutrients (phosphates), low sanitiser levels and poor filtration.

Algae Type: 100 ppm

What type of algae?

Total Alkalinity: 100 ppm

0 300
Ideal 80 - 150

    Ideal Range

    Ideal 80 - 150

What is total alkalinity?

Total Alkalinity shows how much alkaline substances are in the pool water. It indicates the “buffering capacity” of the water to stop wild pH swings.

Why is important to keep Total Alkalinity in range?

Low Total Alkalinity makes the pH level unstable and minor additions of chemicals cause wild swings in the pH. High Total Alkalinity can lead to scaling of the pool surface and cloudy water (if Total Alkalinity is too high, the pH will tend to drift upwards automatically).

When to test for Total Alkalinity?

Before adjusting your pH level.

pH: 100 ppm

0 300
Ideal 80 - 150

    Ideal Range

    Ideal 80 - 150

What is pH?

pH expresses the acidity or alkalinity of the pool water.

Why is important to keep pH in range?

Low pH indicates the pool water is acidic and corrosive to swimmers and pool equipment. High pH indicates alkaline pool water which can cause scaling on the pool surfaces and equipment. High pH also lowers the effectiveness of the sanitiser.

When to test pH?

Once a week.

Free Chlorine: 100 ppm

0 300
Ideal 80 - 150

    Ideal Range

    Ideal 80 - 150

What is Free Chlorine?

Free Chlorine is the dissolved chlorine that is available to sanitise pool water and oxidise organic components in the water.

Why is important to keep Free Chlorine in range?

Low Free Chlorine levels can lead to algae growth and cloudy water. High Free Chlorine levels can cause skin and eye irritation.

When to test for Free Chlorine?

  • Once a week.
  • Before adding chlorine.
  • If algae is present.

Combined Chlorine: 100 ppm

0 300
Ideal 80 - 150

    Ideal Range

    Ideal 80 - 150

What is Combined Chlorine?

Combined Chlorine is the chlorine that has been “used up” in the water sanitising process.

Why is important to keep Combined Chlorine in range?

High Combined Chlorine levels can cause skin and eye irritation and smelly pool water. Combined Chlorine also makes it harder for the Free Chlorine ('good chlorine') to sanitise the water.

When to test for Combined Chlorine?

  • If the water smells of chlorine.
  • When skin and eye irritation occurs.

Calcium Hardness: 100 ppm

0 300
Ideal 80 - 150

    Ideal Range

    Ideal 80 - 150

What is Total Hardness?

Hardness is the measure of how soft or hard the pool water is and how much calcium is dissolved in the water.

Why is important to keep Total Hardness in range?

Low Hardness can cause the calcium components been etched from the pool surface. High Hardness can cause scaling of the surfaces and equipment, and cloudy pool water.

When to test for Total Hardness?

  • Beginning of the season.
  • After the rain.

Stabiliser: 100 ppm

0 300
Ideal 80 - 150

    Ideal Range

    Ideal 80 - 150

What is Stabiliser?

Stabiliser, a.k.a sunscreen, cyanuric acid - protects the chlorine from breaking up by sun’s UV rays.

Why is important to keep the Stabiliser in range?

Stabiliser slows down the depletion of free chlorine in the water from UV light. Having good levels of cyanuric acid (stabiliser) means less chlorine is needed to sanitise the pool.

When to test for Stabiliser?

  • Beginning of the season.
  • After the rain.
  • Before adding chlorine

Phosphates: 100 ppm

0 300
Ideal 80 - 150

    Ideal Range

    Ideal 80 - 150

What are Phosphates?

Why is important to keep Phosphate levels in range?

Phosphates act as “food for algae” and can cause accelerated algae growth in swimming pools.

When to test for Phosphates?

  • After the rain.
  • If algae is present.
