NEW IO Diffuser - Acrylic Series - In-Tank CO2 Diffuser

IO Diffuser - Acrylic Series-Tank CO2 Diffuser

I have now tried 4 different brands since my original purchase of my PRO-SE Series - Aquarium CO2 Dual Stage Regulator with Integrated Solenoid over 1 1/2 years ago. I ended back with purchasing this one which I dropped and broke a year ago. None of the others compare. Would not purchase any other brand anymore. Simple the best!

Great diffuser. It works flawlessly

Great but don't last

I have several of these, but they just don't last. Over the past year they all started to break/crack where the diffuser holder and stem meet. When removing the membrane for cleaning, I'll hear a slight click, and then I know it broke - the CO2 will no longer go through the diffuser and instead bubble out from underneath it. Go stainless, or don't remove the membrane for cleaning - keep it all together.
