I am currently brewing my first batch of beer and I have been checking on the temperature every day. Up until now the top of the beer looked normal and was fermenting as I expect. Today however, I looked at the top of it and most of the heaviness was gone which was replaced by what looked like flakes. Is this normal after 5 days?
Most often when I see flakes in primary they are hops particles. If that's what it is, they will settle out over time. When you siphon for bottling or secondary most of them will be left behind.
By the way, I would strongly suggest NOT opening the fermentation chamber every day. You risk infection every time you open it. Just leave it alone for at least a week (preferably two) and monitor temperature with an external temp strip.
