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

First I would like to say that this regulator comes pre-installed. There is no other way to change the outlet pressure than with a needle valve. However, it's tuned to the perfect level for what it's designed for. It's small and super easy to use. It's only one step, so watch out for the pressure when it drops, but for the price, it's a very good deal, especially for a beginner! I've only been using it for a few days but so far so good!
