About this product

API CO2 BOOSTER Freshwater Aquarium Plant Treatment promotes vibrant, healthy aquarium plants with easy-to-use liquid carbon, which is a necessary element used by aquarium plants for photosynthesis. API CO2 BOOSTER Freshwater Aquarium Plant Treatment supplies a concentrated source of carbon in two forms: CO2, as well as simple, organic carbon compounds. This liquid treatment supplies simple carbon compounds and slowly releases CO2 that plants can absorb through the water. May be used alone or with a CO2 system. API CO2 BOOSTER Freshwater Aquarium Plant Treatment is safe for use with freshwater fish and will not alter pH levels in aquariums. Use with API LEAF ZONE and API ROOT TABS Plant Fertilizer for complete plant care.

With API aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

INSTRUCTIONS FOR USE:

Use the API Dosing Cap on Bottle. Add 1 ml for 10 U.S. gallons (38 L) or 5 ml for 50 U.S. gallons (190 L). Dose once a day.
