Gentlemen and ladies: Whatever. The las line in my previous post reads .95 ppm - should be .05 ppm. Big difference. Sorry about that.. The fingers move faster than the brain sometimes. Phill

Evo,
It is always better to edit your original post, than to correct it in
another post. It helps keep the misinformation factor down, and
the correction post may not always be noticed. There should be
an edit box in the right corner of all your posts.

From HOKE'S book "A SINGLE DROP OF LIQUID DISH SOAP CAN BE ADDED.." This will relieve the surface tension and most too all film type of material will settle.. Mark
