Because it is "thought" that sodium was much faster due to its solubility, but in step wedges I found it to be more like pot di in speed. So your science confirms that. Not my experience !

That was back practically before the beginning of time, so not sure I could relocate the strips-- not sure it matters either, but for the record, not so sure... Judy
