Hmm, but they weren't there yesterday?
That's because the krausen hadn't begun yet...you said in the first post that there has been "no activity" well now, this IS EXACTLY the activity, you are looking for.
But if you keep opening it up to check on it you MAY risk infection....
If you meant "airlock" activity, this should prove that airlocks are NOT a guide to fermentation, they are a valve to release exess co2 and to keep oxygen out (which you keep letting in by constantly peaking in.
I will say it again, it is very very difficult to get an infection, ESPECIALLY if this is your first batch of beer, and you did even the basics of sanitization.
Fermentation is not always "dynamic," just because you don't SEE anything happenning, doesn't mean that anything's wrong, and also doesn't mean that the yeast are still not working dilligantly away, doing what they've been doing for over 4,000 years.
You have to learn to trust the yasts, AND that you beer doesn't need to be constantly watched like a newborn baby.
If I can impart one bit of "wisdom" for you on your journey as a brewer it is this;
If you brew from fear, you won't make great beer!
You might make drinkable beer, or you might make crap...but until your realize that your beer is much hardier than you think it is, you won't do some basic things, (like using your hydrometer) to make your beer great.
You just have a typical new brewer fear that your beer is somehow weak, like a new born baby..and will be ruined or die of you look at it wrong...I want to put it into perspective for you, and save you a lot of new bewer nerves...
Beer has been made for over 5,000 years in some horrific conditions, and still it managed to survive and be popular....It was even made before Louis Pasteur understood germ theory....
If beer turned out bad back then more than it turned out good..then beer would have gone the way of the dodo bird, New Coke, or Pepsi Clear...
It is very very very hard to ruin your beer....it surprises us and manages to survive despite what we do to it...
I want you to read these threads and see..

It's not brain surgery, it's a hobby...it's supposed to be something fun, not something we stress out on....and really
most of the time we think a beer is ruined, it isn't!!!!
Got it? Good!!!!!!!!
