Review on 🌿 FZONE 2.5L Aquarium CO2 Generator System: Complete Kit with Regulator and Needle Valve for Thriving Aquarium Plants by Angie Anderson

* Read the instructions carefully, I used 200 g citric acid with 220 g baking soda and 300 ml water, the reaction started the next day when the pressure increased sufficiently. I already had a CO2 diffuser and tube that I had previously bought from RevainPros: * A solid aluminum cylinder with a safety valve that opens if the pressure gets too high * The pressure gauge fits just right * Should have bought the one with the solenoid Valve, I figured I could already use the other one I had, but it's not really any safer for this tank as I understand it. Improvements: The instructions could be a bit clearer, but some preliminary research should do the trick. It might be better if they could combine one with a solenoid valve as a single product without having to buy a separate one
