Green algae respond strongly to bright light conditions as well as unbalanced carbon dioxide and nutrient levels in the water of freshwater aquaria. [ 3 ] Green spot algae (GSA), most likely of the genus Coleochaete , is a spot-forming algae that slowly covers glass, aquarium furniture , and plants.
In freshwater or estuarine systems close to land, nitrate can reach concentrations that are lethal to fish. While nitrate is much less toxic than ammonia, [20] levels over 30 ppm of nitrate can inhibit growth, impair the immune system and cause stress in some aquatic species. [21] Nitrate toxicity remains a subject of debate. [22]
Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.
Keeping the pH in a suitable range (5.0-9.0 for freshwater systems) is crucial to maintain the health of both the fish and biofilter. pH is typically controlled by the addition of alkalinity in the form of lime (CaCO 3) or sodium hydroxide (NaOH). A low pH will lead to high levels of dissolved carbon dioxide (CO 2), which can prove toxic to fish.
It is used as freshwater aquarium plant. It is an invasive plant in some countries.
