Brewing with unfiltered tap water advice

[Buckeye_Hydro]

Why not use a good pinch of Meta Sulphite (Campden)?
It eliminates all Chlorine and Chloramines instantly. You don't have to wait, and takes away the uncertainty it didn't get evaporated overnight.

Or run it through a carbon block.

I currently use 1/2 a Campden tab every time for a 5-6 gallon batch. I was thinking if I can eliminate chlorine from the water by letting it sit, it may be better than adding a Campden to the water.

You'd only need 1/4 tablet per 5 gallons of water (1 tablet treats [EDIT] 20 liter or 5 gallons 20 gallons or 75 liters) but using almost double, as you do, won't do any harm.

I stir in a small, equivalent amount of Potassium Metabisulphite powder when I fill the bucket(s). It dissolves faster than a crushed tablet. I've never been able to taste it.

Can you be sure all chlorine would dissipate overnight, or even over 24 hours, from a (deep) bucket unless it gets stirred a few times?

That contradicts itself, did you mean 1 tab treats 20 gallons?

I recall reading somewhere it was half a tab for 5g but I'll switch to 1/4 based on your advice. Or, maybe because I use 9 or so gallons of water to make wort is why I use half a tab.

I have read 1 tablet treats 20 gals of water. Since my batch targeting 5.5 gals into the fermenter uses around 8 gallons of water, I use half a tablet. For years I just crushed up one tablet per batch, and never seemed to notice it. At some point I tossed half a bag of tablets because I read they can get ineffective with age and I am sure I purchased them 8+ year prior...so I am not too worried about "saving money" using less than half a tablet.

Yeah, sorry, 20 gallons or 75 liter.
I'll fix that.
