Review on 🐠 Efficient U.P. Aqua CO2 Inline Atomizer for Aquarium: 3/4-Inch - 16/22mm by Amy Wilson

I purchased this product a while ago. I set it to maybe 48 hours and noticed a CO2 leak. I tested it with soapy water and the bottom where they added a way to take out the ceramic part was the reason it was leaking. I thought it might be one of the threads I read about on the forums, but it was hacked in a way that couldn't be fixed in the view around the thread part. I wanted to send it back but I'm a very busy person and didn't have time to do so. I would advise you to look for an older model that does not have a removable ceramic as it has never given me any problems.
