Got a Belgian in primary with a blowoff tube because in my last experience with a Belgian dubbel, my carpet needed cleaning. Anyway. I filled a jug with water/starsan and she's a bubbling away. My question here is, do I need to change the water in the jug at all during the fermentation?
I saw a video on the net where a guy found a fly floating in the jug where the blowoff tube was.
