Do I need liquid carbon for my planted aquarium?

Liquid carbon, also known as liquid carbon dioxide or liquid CO2, is offered by many aquarium companies as part of their plant fertilizer collection. You may see it sold in the United States under brand names like Seachem Flourish Excel, API CO2 Booster, and our own Aquarium Co-Op Easy Carbon. Almost all of these products contain glutaraldehyde or similar chemicals, which is known to reduce algae growth within a planted aquarium. When there is less algae competing for nutrients, light, and carbon dioxide, aquatic plants often grow faster and healthier as a result.
