Free Professional Pool or Spa Water Testing
Have you tested your pool water lately?
To maintain a clean, safe, and healthy swimming environment it is important that you use the correct pool chemicals and regularly test your pool/spa water.
Pool Water Testing: What to Test & What it Means
Regular pool water testing is the key to keeping your water balanced and your pool safe to swim in. Our free in-store water testing can help you understand whether your pool water is acidic or alkaline, whether your sanitiser is working effectively, and whether your water chemistry is protecting your pool surfaces and equipment.
At Clark Rubber, our professional in-store water testing process is quick and simple - just bring a sample of your pool water into store in a clean bottle (taken from elbow depth, away from the skimmer returns) and our team will test it for several key factors.
Once complete, you’ll receive a clear water test printout like the example below, and personalised advice on what your pool needs, including recommended products and step-by-step instructions to get your water back into balance.
Each Clark Rubber water test measures the key factors that influence water balance:
- Total Alkalinity shows how stable your water is and helps prevent rapid pH changes.
- pH levels indicate whether your water is too acidic or alkaline, affecting comfort, equipment protection, and sanitiser performance.
- Free Chlorine reveals how much active sanitiser is available to kill bacteria and control algae.
- Salt levels ensure saltwater chlorinators can produce consistent chlorine.
- Calcium Hardness helps prevent equipment corrosion and surface scale.
- Cyanuric Acid (stabiliser) protects chlorine from the sun, so it lasts longer.
- Phosphates, if too high, can feed algae growth, so keeping them low supports a cleaner, healthier pool.
Maintaining a healthy swimming Pool or Spa
Maintaining a healthy pool or spa involves knowledge and management of these areas as well and seeking professional advice and quality products from your local Clark Rubber store:

- Balancing your water
- Sanitising your water
- Avoiding and fixing green pools
- Pool clarifier and flocculants
- Protecting your pool surfaces and pool stain removal
The water testing process:
A water test will tell you everything you need to know about the health of your pool water in only 60 Seconds .
It’s actually a simple process but it does require the right equipment and the right expertise.
- First you need to collect a sample of water from about an arm’s length below the water surface and bring it to your nearest Clark Rubber store.
- Clark Rubber then uses state of the art testing equipment with special reagents and software to analyse the water to provide a high level of detail about the water chemistry.
- After the water analysis our pool professional can present a report showing you what the critical levels are in your pool, which ones are in the proper range and which ones are out of range and need treatment.
- We will the provide recommendations for the chemicals you will need to treat your water chemistry and to get your water back to health.
What we need to know at your Water Test:
When you come to Clark Rubber for your water test we’ll need to ask you some questions about your pool/spa to ensure we can give the right recommendations and advice such as:
- The volume of water in your pool or spa.
- The type of surface of your pool or spa (i.e. Pebblecrete, fibreglass, tiled, vinyl-lined, concrete etc.).
- If you have a salt/mineral pool and what the recommended salt range is for the Chlorinator.
- If you have a chlorine pool, we’ll need to know which type of chlorine you would generally use (i.e. Calcium Hypochlorite, Stabilised Trichlor, Stabilised Dichlor etc).
- We’ll also ask you about how your pool/spa is looking i.e. Is the water looking green or cloudy?

Total alkalinity is measured in parts per million (ppm) of carbonates and bicarbonate salts in pool water. It helps stabilise pH.
Glossary terms:
Total Alkalinity (TA) — The measure of carbonates and bicarbonate salts in water that helps stabilise pH.
ppm — Parts per million. A standard unit used to measure small concentrations of chemicals in water (for example chlorine, alkalinity, hardness and stabiliser).
