## Overview

## 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. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium. API Aquarium Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your tank. Make sure to use all products as directed in order to ensure the best results.

Review: You need to know what it is! - FIRST you need to know this is not a FIX for CO2 in your tank. NO. It however is a very effective algaecide. Algae require CO2 like all plants to Photosynthesise food. By killing algae you are basically making more CO2 available for your plants. Also if you keep any sort of algae grazers, like Ottos or even shrimp, this could reduce the food available to them. This is a very potent chemical - so use sparingly and as last resort as algae control.
Review: works great - I have a low tech planted tank, i do add liquid fertz once a week but the plants were not getting lush. so i used some root tabs and started to add liquid fertz twice weekly. too much unused nutrients started to cause algae issues. the only solution was to either go with liquid co2 or co2 system. i did not want to invest a ton on money on co2 system so i decided to go with API. when i brought it, seachem Excel was not available. This works great as good as seachem Flourish Excel, within a week algae started to die down and the plant started getting lush. algae did a number of some of my plants but after using this for 1 month and i am happy with the results. the plants are lush and the algae issue is gone. i just wish they would make a larger bottle for cheap, the chemical used is not expensive but they market it as some secret formula and sell it expensive. the base indigent is derivative of glutaraldehyde and you can find many hospitals use it to sterilize medical equipment.

## Questions & Answers

**Q: Can this be used along with co2 supply? Will this be useful to kill algae?**
A: This is not a algea killer, Is your tank newly setup? If its newly setup tank, you will get algea as the plants or unused nutrients in water will promote algea growth.  If you have a planted tank, the plants will grow and use up the extra nutrition and soil will also lose nutrition and algea will stop 

atleast in my personal use, this product never prevented algea. If you have fish in your tank, you can try this, however best cure for algea is constant water change

**Q: What dose it means start up, change water n adding fish?**
A: No, it is for liquid carbon adding to planted aquarium for the purpose of photosynthesis. 

For startup you need to get API quick start, stress Zyme and stress coat

**Q: How often should i use this for my moderately planted 30 l tank**
A: Don't buy. This is not CO2. Simple algaecide. Will kill all moss and anubias

**Q: I do not have a co2 system,can i use this just by itself to help the carpet plants?**
A: Hi,
This is a meant to be a replacement for CO2 system, so you can use this even if you do not have a CO2 system installed in your aquarium.
