eweeewe - how about investing in some photoflow? I recall it being
pretty chepa and it lasts a really long time - you jsut use a tiny bit.
You don't have the wetting agent in the tank for the whole washing
process do you?
You should only do it for about a um less than a minute, and agitate it
all the time.
Sounds like there's also a hard-water problem. Limestone = calcium.
Hard water makes soap films stickier & harder to remove. If you're using
dish washing detergent as a wetting agent, hard water would make it more
prone to leaving behind a soap film on the dried negatives.
You need something like a BRITA filter to remove the calcium from your
rinse water and I concur with the recommendation to switch to PhotoFlo
as your wetting agent.
