## Description

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.

Review: Daily use in Planted tanks. - Using in a freshwater planted tank, our plants have never looked better. The plants are producing off shoots and the fish are doing fantastic. We use this CO2 daily on our fish aquariums!! When delivered cold The plastic did crack due to me dropping the bottle. I was able to save the contents of the bottle in the last bottle I bought meaning I buy this often. The size of the bottle is 8 ounces, fits under the tanks on the shelves well.
Review: This stuff really works - This booster definitely works well for aquarium plants. It's not so good for snails and shrimp. If I put slightly more than the recommended dosage it kills off pest snails and my Nerite snails and Ghost shrimp! So follow the dosage instructions. The plants do very well.

## Questions & Answers

**Q: Can this be used for hydroponic systems?**
A: We do not recommend any of the API products that are for any fish or plants meant for human consumption.

**Q: Is this safe to use with Bettas and glass catfish?**
A: I would suggest to treat the plants in a separate tank without fish  (1 gallon) to be in safe side. Once the plant is healthy you can use it in the fish tank.

**Q: Does this come in pond strength?**
A: This does not come in larger amounts for ponds.

**Q: My tank is bright neon green and it's been running for a week with no light. It's also planted, will adding the CO2 booster help my algae bloom?**
A: Using API CO2 Booster will help the plant thrive and reduce algae growth.
