The Role That Water Chemistry Plays in Your Pool Maintenance

If you’re a pool owner on the Gold Coast, it’s essential to understand the importance of maintaining proper water chemistry. Not only does it ensure that your pool stays clean and safe for swimming, but it also protects your equipment from damage and prolongs its lifespan. In this blog post, we’ll delve into the specifics of water chemistry and how it affects your pool cleaning routine.

The Basics of Water Chemistry

Before we dive into the nitty-gritty details of water chemistry, let’s review some basics. Your pool water is made up of a variety of chemicals that work together to keep it balanced. These chemicals include:

  • Chlorine: This is the most common sanitiser used in pools to kill bacteria and algae.
  • pH: This measures the acidity or alkalinity of your pool water on a scale from 0-14.
  • Total Alkalinity (TA): This measures the number of alkaline substances in your pool water, which helps buffer pH levels.
  • Calcium Hardness: This measures the amount of dissolved calcium in your pool water.

Ideally, you want all these chemicals to be within specific ranges for optimal pool health.

Why Water Chemistry Matters

When your pool’s chemical levels are out of balance, several issues can arise:

  1. Algae growth: If there isn’t enough chlorine in your pool, algae can quickly take over.
  1. Skin irritation: High pH levels can cause skin irritation and red eyes.
  1. Equipment damage: Imbalanced water chemistry can cause corrosion or scaling on your equipment, leading to costly repairs or replacements.

By keeping an eye on your pool’s chemical levels and adjusting them as needed, you can avoid these problems altogether.

Testing Your Pool Water

To maintain proper water chemistry in your Gold Coast swimming pool, you need to test it regularly. You have two options here:

  1. Test strips: These are basic strips that you dip into your pool and then compare against a chart to determine chemical levels.
  1. Digital testers: These are more advanced devices that give you precise readings for each chemical level.

Whichever method you choose, make sure to test at least once a week during peak swim season (summer) and once every two weeks during off-season months.

Balancing Chemical Levels

Once you’ve tested your pool’s chemical levels, it’s time to balance them if needed. Here are some general guidelines for each chemical:


The ideal range for chlorine is 1-3 ppm (parts per million). If it falls below this range, add more chlorine using tablets or liquid form until it reaches the desired level.


pH should be between 7.2-7.8 for optimal comfort and safety while swimming. If it’s too high (above 7.8), add a pH decreaser; if it’s too low (below 7.2), add a pH increaser.

Total Alkalinity (TA)

The ideal range for TA is 80-120 ppm. If it falls outside this range, add an alkalinity increaser or decreaser accordingly.

Calcium Hardness

The ideal range for calcium hardness is 200-400 ppm for concrete pools or 175-225 ppm for vinyl pools. If it falls outside this range, add a calcium hardness increaser or use a product specifically designed to reduce calcium hardness if necessary.


Maintaining proper water chemistry is crucial for any Gold Coast swimming pool owner who wants their investment to last longer while keeping swimmers safe and comfortable at all times throughout the year! Remember always to test frequently with either test strips or digital testers so that you know what adjustments need to make when balancing chemicals like chlorine levels within an appropriate range – between one-three parts per million. 

Monitoring pH balance by adding either decreasers/increasers where necessary depending on its current state; total alkalinity should also be kept within an ideal range by using alkalinity increasers/decreasers according to plan before topping up with calcium hardness increasers when required!
