Review on ๐จ CO2 Art Pro-Series Precision CO2 Check Valve โ Ensuring Optimal CO2 Flow for Aquatic Environments by Olivia Herrier
It only works in the air pump accessory
I have had several different check valves and have always had issues with leaking or leaking water. I was a bit skeptical as you literally just plug the tube in, but it works like a dream. Absolutely no leakage or backflow.
- low cracking pressure 1psi
