Algae
In short, algae is an aquatic plant that thrives in the summer sun and water. It can include a collection of weeds and other types of single-celled formations. Moreover, it does not have stems or roots like other traditional plants. Algae can also thrive in a pond where there are minimal oxygen levels. This is why it is essential to have an aeration system to keep the waters moving. By doing this, you can avoid an algae buildup in your pond.Types of Algae
You'll be able to tell what types of algae you have in your pond by its appearance. There are three types of algae that commonly appear in ponds.- Planktonic Algae: The first one is planktonic algae. This type of algae usually forms in the water column and can also change the water's appearance. It can turn your water different shades, including green, bluish-green, or brown. If left alone and allowed to thicken, fish in your pond won't be able to survive as oxygen is quickly depleted.
- Filamentous Algae: This type of algae is commonly referred to as pond scum or pond muck. The algae form a thick covering or mat-like shape on the pond's surface. It floats atop the water, coating parts of the pond completely green and even covering the entire pond if it goes untreated.
- Chara: The Chara algae tends to resemble plants the most. It can have 6 to 16 leaf-like branchlets with thorn-like growths. The branchlets spiral around the stem without any flowers, leaves, or roots. With a quick look, it can resemble submerged plants in the pond.
