Big Blu RT100S High Temp. Leak Reactant 1 Quart
Ultra sensitive — capable of magnifying micro-gas leakage as small as 0.65 oz./year into visible foam "cocoons"
Finds leaks in seconds, non-toxic, oxygen safe
Pinpoints and preserves microscopic leaks up to two hours
Essentially, yes. Just don't want to suck in oxygen while it crashes in the fermenter.
I use a hop spider and let my boil kettle settle after cooling for about 30 min. My yeast cakes sit well below the spigots on my fermenter buckets, so my beer it fairly clean. Mostly just yeast.
First...
:yes: That will work.
If you're feeling froggy, hook up the liquid line (black connector) to the co2 while carbing, the co2 will bubble through the liquid line at the bottom. Don't know if it helps, but I can hear it while shaking to know if I'm getting close.
Where exactly is it leaking? Between connector and post, under post on keg, top of connector? A little lube couldn't hurt. Hook it up, spray with star san or soapy water and snap a pic.
I used a 4oz PB extract in a 5G batch, I felt it was a good amount. I used it in a porter, it was present, not overpowering. I would use it again in the same amount. Also, I added it at kegging.
I'd think as long as it wasn't black sitting out in direct sunlight, it should easily hold ferment temps.
edit. I don't cold crash in the fermenter, try to avoid oxidation.
I go straight to keg with closed transfer after about 10 days, let it sit at 68 for a few days to a week, then into...
