The Cause of Green Algae
Ponds often become challenged by green algae, duckweed and other aquatic plant overgrowth – this creates an unsightly environment that smells and is a fertile ground for mosquito breeding. The sources of this problem are the nutrients, such as grass fertilizers and waterfowl excrement, that runoff into the pond during rain events. These nutrients fuel aquatic plant growth, creating an unsightly and malodorous environment.
Traditional Approaches
The traditional approaches to green aglae control are to treat ponds with a combination of algaecides (commonly copper sulfate) or utilize a pond fountain or a pond bubbler. The following is an overview of the conventional approaches and their shortcomings.
1. Copper sulfate is expensive and BAD for the environment
Copper Sulfate is a toxic chemical. It kills all plant growth in a pond and fatally damages the pond’s ecosystem, including having a detrimental impact on all aquatic organisms. The use of copper sulfate can never be ceased because it fails to treat the cause of aquatic plant overgrowth: the nutrients that are flowing into a pond. These chemical applications can cost thousands of dollars for even modest sized ponds.
2. Pond Fountains are inefficient aerators
Water fountains are often used in an effort to aerate and create turbulence on the waters surface. By adding oxygen to a pond they seek to help manage for algal growth. However, as fountains sit on top of the water, they are only capable of aerating the top of the water column – and they consume large amounts of energy through launching water into the air while not providing sufficient aeration. As a result, costly copper sulfate treatments are required to control green algae.
3. Pond Bubblers are ineffective
Microbubble aeration systems are submerged at the bottom of the pond, and by bubbling air from the bottom upwards they are able to add oxygen to the entire water column. However, bubblers are not able to create sufficient mixing of bottom sediments and consequently are unable to prevent algal growth by themselves – additional chemical treatments are required.
The 'Green Approach'
The MARS pond aeration system is a chemical free green algae control solution. The MARS uses patented Double Bubble technology, which is able to both mix and aerate, to create a sustainable pond ecosystem. By using processes found in nature, the MARS is able to effectively and efficiently oxygenate (break down by adding oxygen) the nutrients that runoff into a pond and therefore prevent them from fueling aquatic plant growth.
The MARS creates beautiful pond ecosystems that:
