My c-pap gurgles near the end of a the sleep cycle. Not always, but often. Sometimes there is water in the tube sometimes not. It wakes my sleep and I can’t figure out how to stop it. I raised and lowered temperature and humidity levels.

Turn down your humidification. That’s all you have to do. You probable have a Resmed Airsense 10 with a humidification level above 6

You are filling your tank too full and water is getting in the hose. Back off on the level of water and it will stop.
