Ok having said (benefits of the minerals) that I would have to assume that the "mineral pack" that they say you must replace every season for anywhere from $79-$99 is unnecessary. I know of people that have an inline chlorinator and no mineral pack. Their marketing states the mineral pack must be replaced seasonally and even if not used for a whole season if allowed to dry out.

Personally I would like to see or hear from someone regarding the validity and necessity of the mineral pack
