Hello, i just calibrated my pH pen but pH Down dosage seams unreal. Im using this pH DOWN and right now according to my pH pen it says on 10l water I need to use 4ml of Ph down to get pH 6.0
One year ago I was using same pH down but withouth - 30% and on 20l water I was using 3ml pH down to get 6.0 pH. Is its possible or my pH pen shows bullshit (New) ? How much you guys need to use pH down to get your wanted pH?
