FZONE 2.5L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator And Needle Valve for Aquarium Plants Tanks

PROFESSIONAL DIY KIT! A complete system in 2.5L size bottle, that includes SUS304 stainless bottle, regulator, precision needle valve, and easy adjustable bubble counter

ATTENTIONS: Solenoid NOT included, need order separately. Citric acid and sodium bicarbonate NOT included

NEEDLE VALVE WITH BUBBLE COUNTER! High precision, aquarium specific needle valve provides accurate fine-tuning. Steady 1 bps is achievable. Bubble counter with check valve built-in. It stops water from back flowing into your CO2 tank (protects your CO2 tanks from rust and corrosion)

SAFE! The bottle body is made of 1.5mm thick SUS304 stainless steel (25% thicker than normal 1.2mm bottle). It can sustain pressure up to 80kg/cm2(or 1137 PSI). Safety valve will open automatically when the inside pressure exceeds the safety threshold

OPTIONAL: 12V DC SOLENOID! Having the solenoid on a timer, you can specify when you want CO2 injection ON and for how long
