Am not Tom, but I think I can offer some thoughts here.
This summer I had a pouring demo at the Rantoul NATS.
There were a few things I took home from that.
1) the microfilm solution must touch the water in an unbroken stream. Any breaks or drips would inevitably result in an unliftable sheet. I did the pour very close to the water surface, likely within an inch.
2) Speed of the pour somewhat determines thickness.
3) The surface of the water's cleanliness makes a huge difference in how well the solution spreads out. The solution will often go around something rather than push it out of the way, leaving a hole or gap in the sheet.
If would not at all surprise me that adding surfectants would help with a pour and/or get more consistent sheets.
Nearly all of the broken sheets we had were due to bad pours(drips and broken streams) and surface cleanliness, with a few due to frames that were not stiff enough.
I suspect an aquarium filter could do the trick better than the old newspaper trick, if you can find one that will fit the tank. Pour a couple sheets, run the filter, then do a few more.
Regards.
