Hi, I recently purchased Chihiros inline CO2 diffuser. I have a problem with it. It makes giant bubbles and I expected fine mist. I rechecked the diffuser head and I think it is screwed in tight. The pressure is approximately 0.4MPa (60psi).

EDIT: I decreased the pressure to 0.35MPa (50psi) and now it is working fine.
