From Plant Science to Aquarium Equipment
Who We Are Today
ABC Plants is a U.S.-based aquarium equipment company located in Wiscasset, Maine. We design and sell carefully engineered products for planted freshwater aquariums, with a primary focus on CO2ONE—a simplified CO₂ injection system that makes carbon supplementation accessible to aquarists of all experience levels.
Our approach to equipment design is grounded in an unusual foundation: ABC Plants began as a plant tissue culture research laboratory. Years of scientific work studying plant physiology, carbon limitation, nutrient uptake, and acclimation stress directly inform how we design equipment today.
How It Started
ABC Plants was founded after a catastrophic failure in a planted shrimp aquarium (Read the story here).
After introducing what appeared to be a harmless aquarium plant, an entire thriving shrimp colony was lost within hours. Subsequent research revealed the cause: pesticide residues commonly used on exported aquarium plants—chemicals considered safe for fish but highly toxic to invertebrates like shrimp.
That experience exposed a deeper problem in the hobby at the time: many planted aquarium failures were not caused by poor husbandry, but by invisible biological and chemical constraints that were poorly understood and rarely discussed.
Rather than walking away from the hobby, we began investigating the problem scientifically.
Plant Research Years: Montreal Laboratory (2015–2023)
To better understand plant health at a fundamental level, ABC Plants established a plant tissue culture research laboratory in Montreal, Canada. This work was supported in part by Canadian R&D grant funding and focused on controlled experimentation rather than simply commercial-scale production alone.
Between 2015 and 2023, our team developed proprietary tissue culture techniques and conducted extensive research into:
-
Plant acclimation and stress responses
-
Carbon limitation and plant metabolism
-
Nutrient uptake and growth regulation
-
The biological causes of failure in planted aquariums
This work produced unusually detailed plant documentation and hands-on experimental insight. While ABC Plants no longer produces or sells live plants, this research remains a core intellectual asset and the foundation for everything we do today.
The Pivot: From Plants to Equipment
Although our plants had gained a cult following within Canada, by 2023, it became clear that our greatest value was not in producing plants—but in understanding why planted aquariums succeed or fail.
Our research consistently pointed to one limiting factor: carbon availability. We understood how and why plants struggle when CO₂ is insufficient, and we also saw that existing CO₂ injection systems created major barriers for hobbyists:
-
Complex, multi-component setups
-
Lock-in to specific CO₂ cylinder types
-
Safety concerns around high-pressure equipment
-
High upfront costs and confusing logistics
The solution was not better plants—it was better equipment.
ABC Plants relocated operations to Wiscasset, Maine and shifted its focus entirely to aquarium equipment design, applying plant science to solve real-world problems for aquarists.
CO2ONE: Equipment Designed by Plant Scientists
CO2ONE is the result of that shift.
It is a simplified CO₂ injection system designed to remove complexity while preserving flexibility. CO2ONE allows aquarists to choose their preferred CO₂ source—including SodaStream cylinders, paintball tanks, or standard CGA-320 cylinders—without complicated setups or specialized technical knowledge.
By designing equipment from a plant biology perspective, CO2ONE makes carbon supplementation more approachable for beginners while remaining adaptable for experienced aquarists.
Our Mission Today and Looking Forward
ABC Plants is now focused exclusively on designing and selling aquarium equipment for planted freshwater aquariums.
We maintain our historical plant research as an educational resource through our Aquarium Plant Encyclopedia, preserving the knowledge developed during our Montreal laboratory years. However, ABC Plants no longer produces or sells live plants.
That chapter of our history provided the scientific foundation for our current work. Today, our mission is to create equipment that addresses the real biological constraints in planted aquariums—designed with intention, informed by research, and tested by experience.
Our plant physiology expertise continues to guide future product development as we work on additional equipment solutions for planted aquariums.
We believe the best tools come from understanding the biology first—and designing the solution second.
