About this product

Thicker and more durable! Fzone DIY CO2 cylinders are more durable and thicker than ordinary cylinders! Our cylinders are made of 1.5mm thick SUS304 stainless steel, with a robust inner wall that holds more feed, making them 25% thicker than similar products. Fzone CO2 aquarium kits can withstand pressures up to 80kg/cm², and with 300-400g of feed, running for 8 hours a day, they continuously produce CO2 at a rate of 1 bubble per second for up to 1 month. Choose Fzone for a longer-lasting and more efficient CO2 solution!

Professional DIY Kit – A complete 2.5-liter system including a SUS304 stainless steel cylinder, regulator, precision needle valve, and easy-to-adjust bubble counter.
