I tend to look at it as a percent variance. 2% I'm totally OK with; 5% is where it starts to bug me.However, this is 12% variance. Definitely sufficient for calling AHS and tsk-tsking them.
I questioned the guy before and he gave me some BS about it may heat up and expand so they can't fill them to 5#s.Temperature change isn't going to affect weight/mass.
For the record, I wish my starter kit had come with an immersion chiller instead of a glass carboy. Or a bucket with a hole in it, for that matter (it was meant to be a bottling bucket, but I'm finding it it relatively worthless as I prefer to bottle with a siphon). I'm waiting to see if I get the chiller for Christmas; if not, it's the first thing I'm getting with Christmas money.Honestly, I haven't seen a kit with a wort chiller. I bought my kit, a turkey fryer (with 7.5 gal pot) and a wort chiller before my first batch. I have been using the 7.5 gallon pot even all grain. I plan on upgrading to 15gal eventually, but 7.5 is great for full boil extract batches, and is only a bit small for all grain.
I found one kit with a wort chiller in it, the kit upgrade #3 might be where i'm going to start.

I suspect it depends how much you use. Tried some nasty-finishing beer at the last homebrewers' meeting that more experienced tasters and brewers than me (read: BJCP National) said was iodophor.I
P.S. no reason to rinse iodophor

My house always sits in that range, too, but I use a water bath. My logic is that this cushions the temperature swings substantially and helps to keep the temperature down during the stages when fermentation is really going. During that time, the temperature inside the fermenter can get quite a bit over the ambient temperature, so cooling is helpful.for my second batch i was thinking of starting fermentation right away in the Carboy, then use a water bath with a fish heater in the 72 degree range what do you think?
I think 72 is to warm. Think maybe 65.
if 65 is better then i wont need to do a water bath, i thought i would have started at a higher temp to get the yeast going. My house normally sits right around 65-68, but what about the carboy idea?
Good thing with CO2, at least, is that if you're in an area with excessive levels of it, you quickly feel breathless. (Not that you'd want to go down to a basement where it's pooled, but if you're aware of the effect and can easily escape, you've got built-in sensors for it.) That's not the case for other gasses -- for example, there are plenty of horror stories about people working with liquid nitrogen in enclosed spaces who never knew what hit them.Breweries with basement fermentation areas need to have CO2 alarms, as the CO2 source will pool. I worked in a place with sources in the form vehicles, and the confined spaces had to be tested before entry (think the pits for hydraulic hoists) as the heavier gases would pool. The mixing of gases from diffusion is not instantaneous.He said "oxygen." When you have liquid in the PET bottle you can squeeze all the air out before capping it with the carbonator, then add CO2, but with hops, I don't think you can do that, so there will be some O2 in there, but very little.So, how does the oxygen that is in there get purged?
like any standard pin lock - depressing the poppit in the middle.
I have always assumed that the idea is to fill the container with co2, wait a bit for things to settle down in there and then purge through a top opening which should get most of the o2 out as it will have migrated to the top portion of the container. still some o2 but a lot less
That's not how gases work. Otherwise, basements would be deadly. :-)

OK, I stand corrected. I'm more familiar with it in gaseous form, as some of my lab-mates have been looking at the mechanisms by which it kills bacteria.Oh, and bleach is a sodium hypochlorite solution. Chlorine dioxide is a gas (though there are tablets that release it for hikers purifying water), and you need a specialized chamber to use it. Good for hospitals and the like using equipment that can't be autoclaved.
Aqueous ClO2 is a pretty common CIP sanitizer. It's shipped as a 5% alkaline solution (pH ~9) and then acidified just prior to use. http://www.fivestarchemicals.com/wp-content/uploads/StarXeneProductSheet.pdf
No concern about evolving chlorine gas unless the pH drops below 3.
