Does your pond look green before your eyes?

If that is the case, it is now time for action!

Green water indicates floating algae, characteristic of warming and standing water in a pond. In the spring this is a “problem in development ”, if the weather gets really warmer you have a high chance of a “floating algae explosion ” and your pond water becomes green soup, of course you don’t want that.

Floating algae are not really harmful in themselves, but the consequences of a floating algae explosion may be.

• Still and warming water leads to a lack of oxygen in a pond
• Sunlight can no longer penetrate and stagnates plant growth
• Fish can even die in the event of a lack of oxygen.

 

Aeration and movement is an effective solution

There are many options for fighting floating algae. A very effective and natural way is the aeration and movement of pond water. By introducing flow into the water, the warm top layer of the pond water is mixed with the colder underlay. That warm top layer is the ideal breeding ground for floating algae to multiply exposively and you want to get rid of that.

Aeration and movement of pond water is always an advantage during summer days, because warm water contains less oxygen. High fish stock and the presence of organic waste (leaves and sludge) also contribute to this.

A somewhat lesser known cause are organic fertilizers that are present in garden soil, such as phosphate and nitrate. With a rain shower, these can end up in the pond, which are extra nutrients for algae.
