hey guys, i want to treat my next batch with campden tabs but have a quick question regarding the use. I know a single tab will do about 20 gallons, so I plan on splitting a single tablet and crushing it. The issue is, I heat the strike water first (like most do) and because I double batch sparge I heat each sparge separately. When should the tablet be added? my instinct says it should be split up and added to each container of water as it heats, but I was hoping I could add it to the strike water and the active properties of it would also work on the sparge water later as it is added to the kettle through sparging.
