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.
