ABC Plants is a U.S.-based aquarium equipment company specializing in planted freshwater aquariums.
The company began as a plant tissue culture research laboratory focused on aquatic plant physiology — studying carbon limitation, nutrient uptake, and the biological causes of plant failure in closed aquarium systems. That research foundation directly informs how we design and select equipment today.
Our primary product, CO2ONE, is a simplified aquarium CO₂ injection system developed to address real-world carbon limitation in planted tanks. It allows aquarists to use SodaStream cylinders, paintball tanks, or standard CGA-320 cylinders without complex regulators or rigid configurations.
CO2ONE has earned consistent 5-star customer reviews for reliability, flexibility, and ease of use across a wide range of aquarium setups.
In addition to CO2ONE, ABC Plants offers carefully curated planted aquarium equipment — including lily pipes, aquascaping tools, water testing supplies, and maintenance equipment — selected to support stable, biologically balanced aquatic plant growth.
