F30i mask - large leaks

[Franko39]

Hi again everyone,

I'm a fairly new CPAP user who has finally managed to master the basics and keep a mask on overnight. I'm using the F30i mask with the ResMed 10 (AHI = 10 pre-treatment). A new problem I'm having is fairly large, over the red-line mask leaks with the F30i mask (ResMed 10). The leak trend seems to show worsening of leaks later on in my sleep cycle, so likely as I'm tossing and turning more in deep sleep. I've tried tightening the mask more, but overtightening results in mask pressure/discomfort and a higher likelihood that I rip off the mask while asleep.

Attached are a couple of my typical nights and the leak patterns. Any suggestion for fixing the leaks would be appreciated!
