whomeverwiz Posted October 26, 2023 Share Posted October 26, 2023 I hav co-op regulators, and the diffusers they sell, have always worked fine in my first couple of tanks. The third one, however, keeps popping the airline off of the diffuser. I come home, and the line is loose in the tank. I put it back on, and it seems fine, but then it's not attached again. What gives? This tank is bigger and deeper, but I can't come up with any other meaningful differences. Link to comment Share on other sites More sharing options...
TheSwissAquarist Posted October 26, 2023 Share Posted October 26, 2023 Try using some ziplock cable ties to keep it attached. Is the end of the airline stretched? Link to comment Share on other sites More sharing options...
nabokovfan87 Posted October 26, 2023 Share Posted October 26, 2023 Use a cup of hot water on the tubing and then you can get it over a bit further on the CO2 diffuser tubing. That being said, also make sure you're using proper CO2 tubing as the neo diffusers are specifically designed for that internal hole size. This is the one I run now, same company, just a slightly different shape on the end. 90 degree bend instead of 180. Tubing is the same though.

Sounds like the end has lost its elasticity. Edited October 26, 2023 by Chick-In-Of-TheSea Link to comment Share on other sites More sharing options...
whomeverwiz Posted October 27, 2023 Author Share Posted October 27, 2023 Will do and report back. I’m using the ACO black airline tubing, and I did try cutting the end off, but I can’t remember if I used a totally fresh piece or a scrap. Thanks!!
