API CO2 Booster – Liquid carbon supplement for planted aquariums that provides an additional source of carbon for aquatic plants. Helps support healthier plant growth, stronger leaves, improved coloration, and a more vibrant planted aquarium without the need for a CO2 cylinder system.

API CO2 Booster is a specialized liquid carbon supplement for freshwater aquariums designed to promote healthy, vibrant aquatic plant growth.

Liquid Carbon Supplement for Healthier Aquarium Plants

API CO2 Booster is a liquid carbon supplement designed to provide aquarium plants with an additional source of readily available carbon, one of the most important nutrients required for plant growth.

Just as terrestrial plants require carbon dioxide from the atmosphere, aquatic plants require a source of carbon to support photosynthesis, growth, coloration, and overall health.

In many aquariums, carbon can become a limiting nutrient, leading to:

• Slow plant growth
• Yellowing leaves
• Weak stems
• Poor coloration
• Plant melt
• Increased algae problems

API CO2 Booster helps supplement available carbon and is commonly used in planted aquariums ranging from beginner setups to advanced aquascapes.

Unlike pressurized CO2 systems, API CO2 Booster offers a simple liquid alternative that can be added directly to the aquarium as part of a regular maintenance routine.

Provides Essential Carbon for Plant Growth

Aquatic plants rely on carbon to produce energy through photosynthesis. API CO2 Booster supplies a concentrated source of liquid carbon and organic carbon compounds that plants can easily absorb and utilize for healthy development.

Supports Lush and Vibrant Aquatic Plants

Regular use helps promote stronger growth, richer coloration, and healthier foliage, making it ideal for planted aquariums ranging from beginner setups to advanced aquascapes.

Dual Carbon Delivery System

This innovative formula provides carbon in two forms: direct carbon compounds and a slow-release source of CO2. This dual-action approach helps ensure a consistent supply of carbon for aquatic plants throughout the day.

Can Be Used With or Without a CO2 System

API CO2 Booster is flexible and easy to use. It can serve as a standalone carbon source in planted aquariums or be used alongside traditional CO2 injection systems to further support plant growth.

Safe for Freshwater Fish

Specially formulated for planted aquariums, this treatment is safe for freshwater fish when used as directed and will not negatively impact aquarium inhabitants.

Will Not Alter pH Levels

Unlike some CO2 injection methods, API CO2 Booster provides carbon supplementation without causing significant pH fluctuations, helping maintain a stable aquarium environment.

Ideal for Complete Plant Care

For best results, API CO2 Booster can be used alongside API Leaf Zone and API Root Tabs to create a comprehensive nutrient program that supports healthy root systems, vibrant leaves, and overall plant health.

Dosage Instructions

Initial Dose – Add 10 ml per 40 litres (10 US gallons) of aquarium water.

Daily Maintenance Dose – Add 5 ml per 40 litres (10 US gallons) of aquarium water once daily.

Expert Recommendation from Something Fishy

One of the most common reasons aquarium plants struggle is a lack of available carbon.Many hobbyists focus heavily on lighting and fertilizers while overlooking carbon supplementation.API CO2 Booster is particularly useful for aquarists who want to improve plant growth without the complexity, cost, and maintenance associated with pressurized CO2 systems.

For beginner and intermediate planted aquariums, it remains one of the easiest ways to support healthier plant development.
