Fits my Poseidon well. Solid purchase.
Works exactly how it says!
Bubbler adapter works pretty well only down side is it’s a bear to remove. Also no posiedon bubblers so I had to order one from different company still waiting to receive hopefully it’s the right diameter
This is a well designed piece that fits.
I wasnt impressed with the silicone o rings fit with the bubbler, it sagged under the weight and wasnt tight. I swapped to rubber o rings and it worked perfectly, great little atrachment for the bubbler and sai top airflow cap.
