Ok.. I've read through a lot of post and have come to realize beginners are paranoid. So sorry upfront. This is my second batch it's a witbier. My 1st batch an irish stout seems to be going good. Should be popping a bottle this weekend to try it. My issue with the witbier is a slimy looking "film" on top. I'll try to post pics. I pulled the blowoff tube and smelled it but that film looks horrible. The 1st pic is 24 hrs in.. it was bubbling away pretty good after 12 hrs.. the other two pics are 48 hrs out.. at 72 hrs it still looks about the same.. maybe thinner. Thanks in advance
