Built with durability in mind, this complete DIY kit uses a robust SUS304 stainless bottle and a precise control system to support consistent dosing, even during longer lighting schedules.\u003c\/p\u003e\n\u003cp\u003eDurability and safety are built into the core of the design. The bottle features a thicker interior wall (1.5 mm SUS304 stainless steel), about 25% thicker than typical alternatives, enabling it to withstand higher pressure while holding more raw materials. When filled with 300–400 g of raw materials, the system can generate CO2 for roughly a month at a steady 1 bubble per second (bps) for 8 hours a day. This combination of strength and efficiency helps you minimize refills without sacrificing performance.\u003c\/p\u003e\n\u003ch3\u003ePrecision control, safety, and smart operation\u003c\/h3\u003e\n\u003cp\u003eKey controls are easy to fine‑tune: a dedicated regulator and a high‑precision needle valve allow fine adjustments to the CO2 flow, with a bubble counter that includes a built‑in check valve to prevent backflow. This helps protect your equipment while delivering consistent dosing for your aquascape. A 12V DC power setup enables timer‑driven CO2 injection, so you can schedule injections to match your tanks’ light cycle without manual intervention. The system includes a safety valve that opens automatically if pressure rises beyond the safe threshold, adding a practical layer of protection during setup and use.\u003c\/p\u003e\n\u003ch3\u003eWhat this kit offers for real‑world use\u003c\/h3\u003e\n\u003cp\u003eDesigned for hobbyists who want a complete, compact solution, the FZONE kit fits into many standard planted tank setups. The 2.5L bottle size keeps the footprint manageable while still delivering meaningful CO2 output for day‑to‑day needs. Note that powders to generate CO2 (citric acid and sodium bicarbonate) are not included and must be purchased separately if you don’t already have them.\u003c\/p\u003e\n\u003ch3\u003eWhat you get\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5L SUS304 stainless bottle\u003c\/li\u003e\n  \u003cli\u003eRegulator\u003c\/li\u003e\n  \u003cli\u003ePrecision needle valve\u003c\/li\u003e\n  \u003cli\u003eBubble counter with built‑in check valve\u003c\/li\u003e\n  \u003cli\u003eSafety valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n  \u003cli\u003ePowders for CO2 generation are not included and must be purchased separately (citric acid and sodium bicarbonate).\u003c\/li\u003e\n  \u003cli\u003eSupport: FZONE Customer Service offers round‑the‑clock assistance for product questions or setup tips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhether you’re refreshing an established aqua‑scape or starting a new planted tank, this CO2 generator system provides a solid foundation for consistent performance, flexible timing, and practical safety features.
