The water in my pool is green, what should I do?

My pool water is green, what should I do? / Dear pool aficionados , the war against green water is an ancestral battle, isn't it? Who has never sighed in front of this once clear pool, now a color reminiscent of spinach soup? If you are nodding your head, know that you are not alone. At Foudebassin.com, we understand your pain and, even better, we have the solutions!

1. Water quality: more than just clarity

Water quality is the cornerstone of a healthy pond. Water hardness levels, including total hardness (GH) and carbonate hardness (KH), are critical. Water that is too soft can lead to algae blooms. That’s why it’s imperative to test these hardness levels regularly. If they are low, minerals such as calcium or magnesium carbonate can be added to rebalance the water.

2. Aquatic plants: your allies in the war against green water

The power of plants is often underestimated. In addition to their aesthetic beauty, they play a crucial role in the pond ecosystem. Plants compete with algae for nutrients, particularly phosphates and nitrates. The more plants there are, the less likely algae are to proliferate. Think of water lilies, pondweed or bulrushes, which, in addition to oxygenating the water, will limit algae growth.

3. Filtration: the art of choosing the right system

Not all filtration systems are created equal. To combat green water, opt for a biological filter. This type of filter promotes the growth of beneficial bacteria that remove organic waste, ammonia, and nitrites. The result? Clear water and a significant reduction in the nutrients algae love.

4. UV lamp: the secret weapon against algae

You’ve probably heard of UV sterilization. It’s like the superhero of algae control. How does it work? UV rays damage the algae’s DNA, making it unable to reproduce. For maximum effectiveness, we recommend a UV lamp of at least 3W/M³ of water. It’s like putting sunglasses on your fish, except these sunglasses zap unwanted algae!

Conclusion :

Dear enthusiasts, the war against green water may seem endless, but with the right weapons, victory is within reach. Remember: quality water, abundant plants, an efficient filtration system and an adequate UV lamp are the keys to success. Arm yourself with patience, perseverance and the advice of Foudebassin.com, and watch your pond regain all its splendor! And remember, each pond is unique, so adapt these tips to your situation for optimal clarity.
