[QUOTE=FrankB]Thanks for that, Les, but what's unhealthy about paranoia?!

I'll add a couple more cycles to my own regime, although I live in a hard-water area and filtering sufficient water for a process run through a jug filter is a major pain! If I ever defect to the digital camp (not likely anytime soon) it'll be film processing that does for me!

I once lived on a farm where the private spring water supply needed filtering and I used to fill a large container with the water and leave it overnight to settle and the syphon off all but the botton 2 or 3 inches. It worked for me although it was not hard water, it was just full of peat and other bits and bobs.
