    My problem was that reasonably fresh XTOL and freshly mixed home-brews were both failing identically. Metal ions were not the problem, because a pre-wash restored normal density. I suggest doing a pre-wash as a precaution; it won't hurt and might help. Some will say that a pre-wash changes dev-times. That's true: Due to higher density with TMY-2, you might want to decrease dev-time.

    i had a very similar problem with a home brew(in another apug thread), an d my problemturned out to be metal ions ,not in the water but in the raw chemicals used!it's not always the water. how did a prewash return density?
