Review on 🐠 Clscea Aquarium CO2 Regulator - Dual Gauge with Bubble Counter, Solenoid Valve, and Single Stage Technology by Vanessa Jones

This is a great little regulator that hasn't had any problems but I had to buy another one because I didn't know about the "end of tank reset". If a single stage regulator rapidly empties its contents due to a drop in tank pressure, the outlet pressure will increase which can result in excessive CO2 being injected into the tank, killing occupants. This can be avoided by checking the regulator's supply pressure and filling the reservoir before it gets too low, or by purchasing a two-stage regulator that will maintain a constant output pressure and not cause output pressure spikes when the supply pressure drops.
