Aquatic Plants

What are algae?
Algae are a large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms. The largest and most complex marine forms are called seaweeds. They are photosynthetic, like plants, and "simple" because they lack the many distinct organs found in land plants. For that reason they are currently excluded from being considered plants.

Algae are an important part of the ecosystems where they occur, but they can also become a nuisance for aquarists, pond keepers and swimming pool owners.

In order to control algae growth, it is important to understand the characteristic of algae, how and why they grow. Just like any other living plant, algae need light, water, nutrients, carbon dioxide and oxygen to stay alive or grow. It produces Oxygen as a bi-product during photosynthesis. So for algae to grow in your pond all it need is enough carbon dioxide, light and nutrition. So by controlling the amounts of light and nutrients, you can control algae growth.

Many different methods can be used to control algae and the bests results are normally achieved by combining several different methods. You can try the following:
--> Limit the amount of light (both artificial & Sunlight) which will reduce the photosynthesis. In most cases Sunlight is the main cause of Algae. So if your tank is exposed to a lot of direct or indirect sunlight, shade it by curtain or blinds.
--> Limit the nutrients (by frequent partial water change) which will make them hungry for food.
--> Introduce algae eating fish or organism
--> Control using commercially available chemicals. Remember one thing that, mass death of algae will drop the Oxygen level sharply and disturb or unbalance the water chemistry.

For ponds and water garden you have few more techniques:
--> Don’t over-feed your fish, which will contribute to additional nutrition.
--> If possible introduce scavenging species that will eat the left-over food
--> Keep your pond heavily planted, so that plants will over compete for nutrients with algae.
--> If you have plant eating fish or other animals in the pond, then chose though and sturdy plants that grows fast.

 Re: Algae and it’s control
Algae growth is inevitable to any marine environment. Algae form to both salt and fresh waters. It's normal to have small population of algae, but uncontrollable and excessive algal bloom is bad to any marine environment. Algal bloom depletes the marine life, causing serious fish kills and toxicity to the environment..


during the first signs of algal bloom, it's important to implement proper algae treatment to prevent the fatal effects of algal bloom.
