Understanding the Causes of a Green Pool

The main culprit behind a green pool is algae growth. Algae are microscopic aquatic plants that thrive in warm, sunny conditions, making Singapore’s climate an ideal breeding ground. Several factors contribute to algae growth in pools, including:

Imbalanced pool chemistry: An incorrect balance of pH, chlorine, and other chemicals can promote algae growth.
Inadequate filtration: A clogged or ineffective filter can allow algae to proliferate.
Poor circulation: Stagnant water provides an ideal environment for algae to thrive.
Environmental factors: Leaves, dirt, and other debris can introduce algae spores into the pool.

Green Pool Recovery Steps:

a. Assess the situation:

First, determine the severity of the algae infestation. Light green pools can often be treated with a few simple steps, while dark green or black pools may require more intensive treatment.

b. Balance pool chemistry:

Test the pH, chlorine, and other chemical levels in your pool. Adjust the chemicals as needed to achieve the ideal balance.

c. Shock the pool:

“Shocking” your pool involves adding a high dose of chlorine to kill off the algae. Use a pool shock product according to the manufacturer’s instructions and allow the chlorine to work for at least 24 hours.

d. Brush and vacuum:

After shocking the pool, use a pool brush to scrub the walls and floor, dislodging any remaining algae. Vacuum the pool to remove dead algae and other debris.

e. Clean the filter:

Clean or replace the pool filter to ensure it is working effectively. A clean filter is essential in preventing future algae outbreaks.

f. Maintain proper pool chemistry:

Regularly test and adjust your pool’s chemical levels to maintain a healthy swimming environment.

  • Tips for Preventing Future Green Pool Problems:
  • Regularly test and adjust your pool’s chemical levels, particularly during periods of heavy use or after storms.
  • Keep your pool filter clean and functioning properly.
  • Run your pool pump for at least 8-10 hours daily to ensure adequate water circulation.
  • Regularly clean your pool skimmer and remove debris from the water’s surface.
  • Trim back overhanging trees and plants to minimize debris entering the pool.

Green Pool Recovery and the Environment:

A green pool is unsightly and can have negative environmental impacts. Algae-infested pools can become breeding grounds for mosquitoes, which can spread diseases such as dengue fever. Additionally, the overuse of chemicals to recover a green pool can harm aquatic life and contaminate the local water supply. By correctly maintaining your pool, you contribute to a healthier environment for your family and the community.


A green pool can be a frustrating and time-consuming problem for Singapore homeowners. By understanding the causes of algae growth and following the appropriate steps for recovery, you can restore your pool to its former crystal-clear glory. Regular maintenance, including balancing pool chemistry, cleaning filters, and ensuring proper water circulation, is crucial in preventing future algae outbreaks.
