Grow a lush, thriving planted tank with a dependable 2L CO2 generator kit that makes CO2 production simple and controllable.
Durable, compact CO2 system uses a stainless steel bottle for reliable, long-lasting CO2 delivery; capacity 2L, height 47 cm, diameter 10 cm, wall thickness 0.12 cm for steady performance.
You generate CO2 through a straightforward reaction—200 g citric acid + 200 g baking soda + 300 g water; one reaction can last 3–4 weeks, and you should start at 1–2 bubbles per second to protect fish.
Safety and flow monitoring are built in: a safety valve auto-vents on overpressure, and a bubble counter helps you visualize CO2 flow and prevent backflow into the regulator.
Everything you need is included: 1x 2L empty bottle, 1x solenoid valve, 1x bubble recorder, 2x sets of raw materials, 1x measuring cup, 1x funnel, 2x suction cups, 1x 2 m air pipe, and 1x 25 cm stainless steel refiner.
