When I first got that crappy SS tank and reel, after practicing loading many times, I put the loaded reel in the tank, poured in plain water, agitated for 1 min, and took the lid off. Lots of bubbles. Then I tapped a few times. Some bubbles remain on film and between turns of the spiral wires. I did this a number of times with varying strengths, and I basically doubled the strength necessary to get all the bubbles off to ensure no bubbles on film.(posted 8282 days ago)
