Review on 🐠 12/16mm CO2 Diffuser & Reactor: Atomizer Bubble Counter for Aquarium Plants, Fish Tank Accessory - Aquarium CO2 Diffuser for Effective CO2 Dissolution by Jennifer Lyon

I noticed right away that the fittings were smaller than my 5/8" filter hoses but luckily I had a smaller hose from an old filter and I can use them as adapters with hose clamps. Product photos show two different sizes but no option to choose from. Installation took only a few minutes and I installed it very close to my filter outlet. It was initially leaking in the center port so I removed and disassembled. I smeared some clean silicone grease on the o-rings and reinstalled with no leaks.At first there was a fine mist at a rate of 3-4 drops/sec but it gradually dissipated.There are bubbles but they are hard to close See The device seems well designed and easy to install I will update in the near future.
