I was knocking up those two kits. I'd put the malt powder in the two FV's. Then, I'd emptied the tin into the first one. Kettle was boiling for the second kit and I stuck the hose in the jerry can .....
Jerry got to the right mark. So, I lugged it over and poured it into the first FV. Just short of four gallons of water.

That's when time stood still, as I tried to remember, and work through all the theoretical crap one sees written about knocking up a kit.
I'd, potentially, just dumped a load of chloramines into my malts? F**ked beer, surely?
This is why we slavishly fret about how well we rinse our bleach sanitised FV's in the first place, yeah? Bleach f**ks beer!
What was I to do? I prepared a crushie and slung it in. Minutes after the bleach hit the malt.
Made the next one, properly. Dunked their heaters in and set them to warm up. That night, I chucked their yeasts in. And came here to make a panicked post about, " What Have I Done?! "
Week later, I got sh!t faced on the gorgeous contents of that FV!

So, what might we extrapolate from all this?
Way I see it is that the sh!t in my tap water has No Effect on Malts. But, then; I never did really think it did.
Timing: How many times do we read stuff like; " Oh, ye must put the crushie in the water, then let it stand ten minutes / half an hour / over f**king night to work. " ?
I've always advocated simply slinging the crushie into the JC and hosing the water in on top of it. Four gallon mark? Ye good to go! F**k standing about, scratching ye balls, while it " Works ".
Chlorine effects Yeast. Not malts. Is this not so ....? (Genuine question) Either way; A crushie knocks chlorine on the head. Boosh! Half an hour doesn't come into it. That's what I reckon.
Further; I'd look askance at some of the continuing mentality about, " Ooooh! Well, if ye use bleach solution to sanitise? Then ye Must rinse ye gear for at least half an hour, of course! "

I sanitise my FV's with a handful of solution made of about a mug of thin bleach in a couple or so gallons of water. Quick hose out and I'm good to go.
Before that yeast even Sees that FV, there's four gallons of water diluting any residue! This is chlorine, people. Not f**king Strychnine! Relax a little!

What ye reckon ....?
