Co2 not diffusing?

I have a diy set up, co2 and diffuser. But over the last couple days the bubbles have not been dispersing in the water column. They are coming out of the diffuser pretty tiny but they just got to the top and that's where they stay.
So what can I do or what is wrong with my setup?

Ceramic disc diffuser? After rolling out that you don't have enough pressure, it might be time be to take that ceramic disc out and clean it if possible. At some point you'll have to buy replacement discs

I believe the main problem with this is that DIY CO2 isn't completely pure CO2. So there will be some left over non dissolvable gas. Have you checked the bottle to make sure it's not reached near the end of it's CO2 production?

If the mixture of yeast and sugar-water is getting stratified with a clear layer of liquid on top, it's time to make a new sugar/yeast culture.
