Crafted FZONE 2.5L Aquarium CO2 Generator System — Regulator Needle Valve Expertly Made

Durable, precise CO2 for thriving planted aquariums FZONE's 2

5L Aquarium CO2 Generator System is designed for plant enthusiasts who want a reliable, low-maintenance CO2 source

The bottle uses a 1

5mm thick SUS304 stainless steel interior wall, making it sturdier than many DIY options on the market

This extra thickness contributes to a more stable CO2 generation experience and helps the system stand up to repeated pressurization when filled with 300–400 grams of raw materials

The unit is rated to withstand up to 80 kg/cm2, which supports longer runs between refills and a smoother, more predictable dosing routine

Built to perform as a complete DIY kit in a compact 2

5L bottle, the line-up includes a high-quality SUS304 bottle, regulator, a precision needle valve, and a bubble counter with a built-in check valve

The safety valve automatically opens if the internal pressure crosses the threshold, adding a layer of protection during operation and giving hobbyists more peace of mind when monitoring a busy display tank

Look for precision control at the heart of the kit

The dedicated aquarium needle valve allows fine-tuning of the gas flow, helping you approach a steady 1 bubble per second under the right conditions

The bubble counter’s check valve minimizes water ingress into the line, protecting delicate components and reducing the risk of corrosion over time

The result is a more confident setup for hobbyists who want to dial in CO2 without guesswork

Power flexibility matters in busy tanks

With a 12V DC setup rather than an AC-powered option, you can pair the kit with a timer to schedule when CO2 is injected, matching your tank’s daily rhythm and plant needs

This makes it easier to experiment with dosing patterns, supporting a hands-on approach to plant growth while avoiding constant manual adjustments

What you should know before you start: the kit is a complete system, but the CO2-generating powders are not included

Citric acid and sodium bicarbonate are typically used to create CO2 gas in DIY formulations and can be purchased separately
