Algae Covered Pond. Algal nutrient solutions are made up of a mixture of chemical salts and seawater. [1] Sometimes referred to as "Growth Media", nutrient solutions (e.g., the Hoagland solution, along with carbon dioxide and light), provide the materials needed for algae to grow.
The Zygnemataceae are a family [2] of filamentous or unicellular, uniseriate (unbranched) green algae.The filaments are septated and reproduction is by conjugation; Spirogyra is commonly used in schools to demonstrate this kind of reproduction.
Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals.

However, total elimination of algae is considered unlikely in a hobby aquarium. Algae can be used as an bioindicator to inform an aquarist on water chemistry and other conditions. [2]
The most basal members are unicellular, but filamentous species have evolved at least five times, [9] and a few species form colonies. [7] Each cell contains a single nucleus. [7] The chloroplasts of the Zygnematophyceae are large, typically axile but sometimes parietally located, and contain one or several pyrenoids. One or several ...
