It should look like mine in the picture after 24 hours… That is the sign of a good tea…
I don’t have a data to support this but I was told it isn’t good to have a lid on top of the bucket you want the tea to be able to gas off… As you see in my picture that is way my bucket is in my flood tray. contains the mess…
With your air pump running do you have a hard bubble action happening?
Maybe compare the specs of your pump see if it has the power
This is my pump
