A green swimming pool can happen faster than most people realise. Heavy rain, hot weather, equipment failures or simply missing a few weeks of maintenance can quickly allow algae to take over. What starts as slightly cloudy water can become a completely green pool in only a few days.
The good news is that most green pools can be professionally restored without draining the water.
At Illawarra Pool Cleaning, we specialise in fast, effective green pool recovery throughout Wollongong, Shellharbour, Kiama and the South Coast. Our experienced technicians diagnose the cause of the problem, treat the algae, restore proper water balance and ensure your equipment is operating correctly so your pool can return to crystal-clear condition as quickly as possible.
Whether your pool is light green, dark green or completely opaque, we have the knowledge and equipment to restore it safely.

Why Do Swimming Pools Turn Green?
Green water is almost always caused by algae growing in the pool. Algae thrive when sanitiser levels become too low or water chemistry falls out of balance.
Common causes include:
- Low chlorine levels
- Heavy rainfall
- Hot weather
- Pool pump failure
- Faulty chlorinator
- Dirty or blocked filters
- Poor water circulation
- Incorrect pH
- High phosphate levels
- Leaving a pool unattended during holidays
The sooner the problem is treated, the easier and more affordable recovery usually becomes.

Can a Green Pool Be Saved Without Draining?
In most situations, yes.
Many pool owners assume that draining is the only option, but this is rarely necessary.
Professional treatment often restores even heavily affected pools while:
- Saving thousands of litres of water
- Protecting pool surfaces
- Avoiding unnecessary costs
- Reducing downtime
We only recommend draining a pool if there are exceptional circumstances where recovery is not practical.
Common Problems We Find During Green Pool Recovery
While treating green pools, we often discover additional issues that contributed to the algae outbreak.
These include:
Faulty Pool Chlorinators
If the chlorinator is no longer producing enough chlorine, algae can develop rapidly.
Worn Pool Filters
Blocked or ageing filters reduce water clarity and limit effective circulation.
Pump Problems
Poor circulation prevents chemicals from reaching every part of the pool.
Incorrect Water Balance
High pH or low alkalinity reduces chlorine effectiveness.
Poor Maintenance
Leaves, dirt and organic debris increase chlorine demand and encourage algae growth.
We’ll explain any issues we find and recommend practical solutions to prevent the problem returning.
