🌿 Yosoo U-Shape DIY 4 in 1 Co2 Diffuser: Enhance your Planted Aquarium with this Complete Co2 System! Review

Inexpensive, works great, easy to set up. I've checked the check valve a few times to pump water out of the tank and it's holding up well. The bubble counter is easy to read. (Hint: if you want to find out how many bubbles you get per second, install any metronome app for your phone that lets you set the tempo. Tap each bubble once.
