Pool Guide

Why do algae appear in a swimming pool?

Algae develop when certain conditions are met:

• Poor chemical balance: An incorrectly adjusted pH favours their proliferation.
• Insufficient filtration: If the water does not circulate properly, it becomes stagnant and conducive to algae.
• Prolonged exposure to the sun: Heat accelerates the growth of algae, especially in summer.

Preventive actions to avoid the appearance of algae

Preventing the appearance of algae is much easier than eliminating them once they have settled. Here are the essential steps:

1. Maintain a good water balance

Test the pH regularly and adjust it if necessary. Well-balanced water reduces the risk of proliferation.

2. Run the filtration long enough

The filtration time should be proportional to the water temperature. Continuous circulation prevents stagnation.

3. Use an anti-algae treatment

Add a preventive product once a week to limit the risk of infestation.

What to do if algae appear?

If algae develop despite your precautions, here are the steps to follow:

1. Perform a shock chlorination. Add a high dose of chlorine to eliminate the algae quickly. 2. Clean the pool manually. Brush the walls and vacuum up the algae deposits to eliminate them completely. 3. Filter the water continuously. Run the pump 24 hours a day until the algae disappear. Prevention and maintenance for an algae-free pool. Good maintenance is the best way to avoid algae. Test the water regularly, clean your pool and ensure optimal filtration to keep your pool healthy and crystal clear.
