for a long time I filtered my water through a brita pitcher. holy snot did this suck. once I discovered campden tablets I was a happy, happy man.

And a Brita pitcher is just a carbon filter right? So that's not going to remove chloramine either.

I thought I heard somewhere that when using campden tabs you have to let the water sit out for a long while for the chloramine to dissipate. Any opinions on this?

I hope that's true. I've been measuring out my water the night before so I can let it sit. I'll probably still do this since it shaves time from the brew day, but nice to know if I get lazy I can just toss in the campden and go.

I should say that charcoal doesn't remove all chloramine. Only about half is what I've read.

if one overdoses the K-meta, like it sounds many are, how could this affect the water profile?

so let's say 450 mg which would be good for 150 L or about 40 gallons. so yeah - I've been overdosing my 10 gallon batches :lol:

I read somewhere that a lot, of the weight was binder. The common stance is that 1 tab is good for treating 20 gallons of water.

There's nothing much left to really let dissipate, after metabisulfite. You basically add a very few ppm of salt and a few ppm of sulfate. If you have little or no chlorine or chloramine, you might have a few ppm of sulfite left over. I don't know if that will survive the mash, boil and fermentation, though.

ah - sounds like my practices are about right then. 1 tab for about 14-15 gallons of water needed for a 10 gallon batch and 1/2 tab for about 7 gallons of water for a 5 gallon batch.

That's what I've been doing forever. Half tab to start, and use the smaller half to top off the EHLT.

On this topic, I had picked up one of those home depot "free" water tests and sent it in...I got a phone call today and the lady says you're water tested positive for hardness, chlorine, and (something else i can't remember). Then she started talking really fast, before I could get a word in, about how they'll send someone out to do further testing. I was like wait what? So your telling me it's chlorine not chloramine? She's like yup, thats what it says. So I told her that I'm a brewer and started talking about how chlorine can be boiled out but chloramine can't and she says "oh, I didn't know that" at which point a red flag shot up. She said someone will call and schedule an appointment to come out.At this point I hung up the phone and started thinking that she really sounded like a sales person...so I googled home depot water testing. Sure enough, it's a sales person that comes to your house to do all of these "tests" and then tries to sell you a $6,400 purification system, which has gotten tons of bad reviews...hah. I guess I'll just pay for a legit water test so I can actually get some useful information. I'll make sure to say something about that when the person tries to schedule an appointment. I'll probably say, hey, all I wanted was a paper with useful information, not someone trying to sell me crap.

Nope. It's a pretty much instant chemical reaction.

send it to ward labs. someone here will tell you which test to run that will have everything you need without any BS or hassle.

I was just talking to dan about that this morning. Will definitely be buying that kit from them...I don't get why the brewer's kit costs $20 more...

i'm sure they offer something extra but I'm guessing not $20 more. i'd stick with the old stand by. it has everything you need as far as I know.

I think they send you a sample jar or something like that.
