The system uses a safe citric acid and sodium bicarbonate reaction to generate CO2, producing high-purity gas and maintaining consistent pressure and flow through a precise regulator, a bubble counter, and a diffuser. Because it doesn’t rely on refillable cylinders, you may experience fewer interruptions and more predictable gas supply during growth phases.\u003c\/p\u003e\n\u003ch3\u003eBuilt for safety and rugged reliability\u003c\/h3\u003e\n\u003cp\u003eConstructed with a food-grade 304 stainless steel body and a thicker wall, the unit is designed to withstand regular operation. The manual shut-off valve gives you direct control when CO2 isn’t needed, while an automatic pressure-relief valve vents excess pressure to guard against overpressure scenarios, offering dual safety protection for worry-free use.\u003c\/p\u003e\n\u003ch3\u003ePrecise control and clear monitoring\u003c\/h3\u003e\n\u003cp\u003eFine-tune the CO2 flow with a precision needle valve, and monitor delivery with a bubble counter and a real-time pressure gauge. The upgraded all-in-one solenoid reduces connections and potential leakage, helping to keep CO2 delivery stable and consistent for a thriving planted aquarium.\u003c\/p\u003e\n\u003ch3\u003eReady to install and use\u003c\/h3\u003e\n\u003cp\u003eThis complete kit is designed for straightforward setup. It includes a diffuser, check valve, U-connector, suction cups, tubing, a funnel, a syringe, sealing rings, and a power adapter—everything you need except the CO2 materials. Simply add your chosen raw CO2 materials and you’re ready to go.\u003c\/p\u003e\n\u003ch3\u003eEasier use and maintenance\u003c\/h3\u003e\n\u003cp\u003eFor easier cleaning, the DIY reactor features an upgraded external thread design that minimizes residue buildup. The bottle opens smoothly, and a built-in fill port lets you add water directly with a syringe—no need to unscrew the cap, saving time during refills and maintenance.\u003c\/p\u003e\n\u003ch3\u003eReal-world benefits you may notice\u003c\/h3\u003e\n\u003cp\u003eUsers often report steadier gas delivery during growth spurts, fewer interruptions from refills, and smoother integration with filtration systems. Individual results vary, but the system’s design emphasizes reliability, ease, and simple ongoing operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncluded components: CO2 diffuser, check valve, U-connector, suction cups, tubing, funnel, syringe, sealing rings, and power adapter\u003c\/li\u003e\n  \u003cli\u003eKey usability features: no extra parts required; just add CO2 materials; integrated safety and streamlined wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What makes the FZONE 2.5L CO2 system different from traditional cylinder setups?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It generates CO2 via a citric acid and baking-soda reaction with integrated safety features.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What’s included in the kit and what else do I need to start?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Includes diffuser, check valve, U-connector, tubing, and more; raw CO2 materials are not included.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"FZONE","offers":[{"title":"Default Title","offer_id":40563878527105,"sku":"B0FRF3W5JS","price":202.94,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0598\/4757\/3633\/files\/fzone-co2-generator-assembled.jpg?v=1765892136","url":"https:\/\/petiva.ca\/products\/fzone-2-5l-upgraded-aquarium-co2-system-integrated-solenoid-safety-valve","provider":"Petiva","version":"1.0","type":"link"}
