Hi everyone. This is my first time brewing mead and the first time brewing anything at all. I started today (January 7th 2023) and the fermenting process seems to have started. Bubbles are rising through the air lock. My question regarding the air lock is this: is it okay for the water to shift inside the airlock? There are two lines indicating the level at which the water should be. I filled it to this line and put it in the hole of the bucket. A few hours later when I came to check up on it, all the water had moved to the left chamber. Is this cause for concern or not?
