Overview

Enhance your planted aquarium with the FZONE 5.5L CO2 Generator System, a sturdy, DIY-friendly kit designed for dependable carbon dioxide delivery. Built around a 5.5L SUS304 stainless steel bottle, this system pairs a precision regulator and needle valve with a bubble counter to help you dial in CO2 at a steady pace. The result is a cleaner, more controlled dosing experience that supports lush plant growth and a vibrant aquatic display.

The bottle system is engineered for safety and durability, featuring a thick-walled 1.5mm SUS304 body that resists wear and corrosion. A safety valve automatically relieves pressure if thresholds are exceeded, providing an extra layer of protection during longer injections. With a robust construction and reliable components, this kit is built to withstand routine use in demanding setups.

What’s Included and How It Works

  • 5.5L SUS304 stainless steel bottle with an elevated 80 kg/cm2 pressure rating
  • Regulator and high-precision needle valve for accurate, gradual CO2 dosing
  • Bubble counter with an integrated check valve to prevent water backflow
  • 12V DC power compatibility for clean, compact integration with a timer (not included)

Benefit in Real-World Aquariums

In active aquariums, stable CO2 delivery matters more than dramatic bursts. The system supports steady tuning, enabling a measured injection pace that can align with plant uptake and overall tank dynamics. The mix of a precise regulator and the fine-tuned needle valve allows gradual adjustments, helping you monitor responses to light and nutrient levels without sudden changes.

This kit is well suited for densely planted tanks, high-light setups, or medium-sized displays where compact gear and reliable performance are valued. The built-in safety features and corrosion-resistant materials help reduce maintenance concerns, letting you focus on enjoying your aquatic landscape.

Setup Notes and What to Buy Separately

  • Powders to generate CO2 are not included; you will need citric acid and sodium bicarbonate
  • To automate CO2 injection, a compatible timer/solenoid is needed (timer not included)
