Oh no! You've just come back from your vacation to find that your pool has turned green. A green pool is not just an eye-sore, but also poses a health risk. Swimming in an algae invested pool can be harmful to both you and your pets, and also attract mosquitoes. We have created a step-by-step guide to help you get your green pool crystal clear!
- Check Your pH Level
The first step to fixing your green pool is checking your water chemistry. The key metric that matters when clearing your pool is your pH. The pH measures the acidity of your pool water, and plays a direct role in how effectively your sanitizer works. The ideal range for your pool's pH is between 7.2-7.6 and is essential to the efficacy of your sanitizer. For example: at a pH greater than 8, only approximately 20% of your chlorine is available to kill contaminants in the water. When shocking your green pool, you will want to ensure that your pH is 7.8 or less.
If your pH reading on your test strip looks pink like this, it is usually a sign that it is too high.

Before treating the algae, clean the pool thoroughly. Here’s what you need to do:
Scoop out Leaves and Debris: Scoop out as much debris from the pool as possible. Organic material such as leaves can eat up your chlorine and reduce the effectiveness of your shock treatment.
Brush the Walls and Floor: Use a pool brush to scrub the sides and bottom of the pool to dislodge algae. Be sure to get into all the corners and along the waterline.
3. Shock Your Pool.
3. Shock Your Pool.
Shocking the pool means adding a large dose of chlorine to kill algae, bacteria, and organic contaminants. Follow these steps:
Brush the Pool: In order for the shock to be effective, the algae needs to be suspended in the water. Brush the walls and floor of your pool to free any stuck algae.
Apply the Shock: For heavy algae infestations, add about 300g of calcium hypochlorite based shock per 10,000 L of pool water. Add the shock slowly to the skimmer with the pump running on high.
Add the Shock in the Evening: To get the most out of your treatment, apply the shock after the sun has set to prevent it from being degraded by sunlight.
Run the Pump: After adding the shock, let the pool pump run for at least 24 hours to help circulate the chemicals and clear the water
The green tint should be gone and your pool should look cloudy like this.
