On hot summer days, we are drawn to the swimming pool, the pond or our own garden pool. But there’s nothing worse than the surprises that may await us once the tarpaulin has been unveiled. That is the unpleasantly and unhealthily green water, which is certainly not inviting for refreshment. The fight for clean water is not as difficult and demanding as it seems at first sight. Tips and advice from pool owners will help anyone who wants to be perfectly prepared for this year’s swimming season.
Algae is the problem
The reason the water is green is quite simple. It is mainly due to the hot weather and the associated algae. These unwelcome micro-organisms are nourished by the sun’s rays and have the perfect environment for growth. The normal way to get rid of this algae is to add a chemical such as chlorine, but if you increase the amount when the water turns green, it may not have the effect you expect. To prevent green water, we recommend covering the pool with a tarp after use and increasing the amount of chemical. If you have not managed to prevent the water from turning green, follow the steps below to remedy this.

How to get rid of green water
Green water doesn’t always mean draining the pool and refilling it with clean water. Now you will need to get rid of the algae that multiplies in the water. We’ve put together a precise procedure that will work on even the greenest water. You will need:
- Pool pH testers
- Chlorine Shock
- Anti Algae
First, check the pH and TA in your pool, using a good quality tester. These values are very important and should be between 100 and 150 ppm and pH 7.0 and 7.4. Now it’s time to shock the green water, so to speak. Depending on the size of your pool, pour the required amount of shock chlorine listed on the label. Now mix the water properly. The last step will be to add the anti algae. It is a liquid substance that kills algae and prevents recurrence. This is the only way the pool water can be purified again. Unfortunately, no other methods where so much chemistry is needed are effective.
