Did i stall my fermentation

[Glynn]

I resided to try a swamp cooler for the first time and kept a temp log

7/2/12
530p pitched yeast @ 72
10pm temp 66

7/3/12
6am temp 66
12pm temp 66 fermentation started
5pm temp 66
7pm temp 68 added ice beer is going strong now 1 in foam on top
10pm temp 59

7/4/12
5am temp 59
330 temp 68 added ice pack
8pm temp 66

7/5/12
730am temp 66 add ice pack
12pm temp 66
1145pm temp 66

7/6/12
the temp has been holding steady 67 at the moment and i am letting it rise, but my airlock has had no activity since late on the 4th. there still a nice 3/4 in head of foam going and i can see it bubbling slowly.

What is it that you were making? I have had low ABV beers ferment in about a day and a half. what is your gravity at?

why do yo think its stalled?

its an IPA. Until now all of my brew were done at 72 I have never tried to control the temp so i am use to seeing a flurry of activity. so i was a little surprised to see my airlock not bubbling. even tho i can see the there's still a good head on it

An airlock is a vent, not a fermentation gauge. A happily bubbling airlock does indicate activate fermentation, but a non bubbling airlock does not indicate lack of fermentation. You see krasuen, you certainly have fermentation.

Leave it alone for a week, then take a gravity reading. Odds are your slighly lower temps are giving you a slightly less vigorous fermentation - and that you probably have a leak in a seal, which is allowing CO2 to escape without havign to bubble.
