My mead is fermenting...slow... I filled repitched some liquid yeast today. I had a little taste of my mead and its carbonated! In the primary! I just aerated the crap out of it and as I did it I could hear and see gas floating to top. I also didn't fill my air lock as high as i usually do since the slow fermentation and might not give off enough Co2 to push the air out of the 3 piece air lock and force it back into the mead. Is this common and should I be worried?

CO2 is a byproduct of fermentation, just like alcohol. The carbonation you're seeing is just dissolved CO2, it'll eventually come out of solution on it's own; nothing to worry about. It'll have enough pressure to get out of the airlock. I wouldn't aerate it any more if I were you, if you do, you run the risk of oxidizing your mead. CO2 actually helps protect your mead from oxidation. Your best bet is to just let the yeast do their thing & wait. Regards, GF.

It could have been fermenting slow due to an excess amount of c02 in solution, it's recommended to aerate it frequently during the first few days when most of the fermentation is occuring. And like gratus says, when it slows down, don't aerate due to... what he said.
