Too much Camden Tablet?

I have a straight forward all 2 row Canadian Dry ale yeast brew that I do and I added a half tablet and did the 5.2 ph mash, plus Knox gelatin to it for the first time in my time doing this hobby. I live in Seattle and the water is considered good. I have done this brew many times before but this first of the ten gallons I brewed is out of the keg really funky. I remember tasting the crushed tablet of camden and the first impression I get is of that. Any thoughts?

I dislike campden tablets and 5.2 pH Stabilizer. I wish I had your water.

I use potassium metabisulfite. I believe camden is sodium metabisulfite. I use it at a rate of .025 grams per gallon of water and have never had any issues.

It's made the few brews I've used it on 'peppery.' I don't know why or how,but I do know it is not good with my water. I used it on three brews. All had the same problem. I stoped using it and drawing water a day before hand leaving it in the sun. The problem was gone. I drank (a lot) this water both ways (as water, not beer) and the campden make the water less palatable. Currently I drink more water than I do beer and I drink way too much beer.

Half tab in enough water for a 10G brew?
