We Queenslanders love the summer heat, but so does pool algae – and the party has started in your swimming pool if you haven’t addressed the issue.

There are over 21,000 types of algae, according to Christ Fitzmaurice, Australasian manager of Swimart.

“If you own a pool, chances are you are familiar with some of them already,” says Chris.

Algal blooms are made up of little aquatic creatures that multiply rapidly on warm daysDuring summer conditions, they can turn your sparkling pool into a cloudy mess overnight.

Luckily, algal blooms can be easily categorised by colour, and can then be treated accordingly.

Here’s a rundown of what causes the different types of algae and what treatment options are available from your local Swimart store.

 

Types of algae:

Green –

This is the most common variety of algae for a pool owner. This type floats freely in the water, and in severe cases, forms an entire film across the surface of the water. It can also cling to the pool walls and other surfaces.

Kill it with: Algatrol, Algae Starver

 

Yellow-

Yellow algae can usually be found clinging to the walls and other pool surfaces. Re-infection is common, as this variety of algae is very hard to kill. It can form even if your pool is balanced correctly and being dosed with the right amount of sanitiser, as yellow algae is resistant to normal chlorine levels. To get rid of it, you must hit it hard with a high dose of chemicals.

Kill it with: Tropical Strength Algaecide

 

Black –

Black algae is the hardest type of algae to get rid of, forming dark spots on your pool surfaces. Occasionally appearing to be a dark green, purple or blue colour, the roots of this variety can bury deep into plaster or tile grout of your pool walls and will put up a pretty decent fight to stay there.

Like yellow algae, this variety can also bloom even if you are properly sanitising your pool.

Kill it with: Black Spot Granular Algaecide, Black Spot Treatment


How to prevent algae:

Dose your pool regularly with the correct amount of chlorine, rather than just chucking a random amount in every now and again.

Check and clean your filtration, pump system and pool cleaner regularly; more efficient equipment equals better filtration and cleaner water.

Cut back overhanging trees and shrubs; go one step further and get that leaf scooper out to get rid of loose leaves that are floating in the pool.
