    What ever you do don't rap a plastic tank hard they tend to break or split, a gentle tap is OK.

    I agree with the others, it looks like air bubbles. Pre-soaking for two minutes with two drops of wetting agent added to the water will help eliminate air bubbles adhering to the film. If you're using a plastic tank, don't bang it too hard - you might crack it! BTDT!

    Good luck,

    Another APUG member gave me this tip, a while ago:
    Get an old, unused mouse pad. One that you won't use for the computer anymore. Put it on the bottom of your sink or counter where you develop film and use that to bump your tanks on.

    I always tap my tanks three times. Old habit. My first photography teacher in high school always told us "three times for good luck."

    Informative, I've never seen/had a "air bell" problem but now I know what they look like.

    I wouldn't have guessed thats what caused this.

    I followed the tapping advice and it works like a charm. Plus I went back to the inversion technique, even tho there are leaks.

    Is there a tank that does not leak? I am using a omega brand tank with plastic reels that I bought at a store here.

    For stainless steel reels - no.

    Although some are much better than others.

    For plastic reels, I've had a variety of experiences. I think this one from Freestyle is same as the AP brand tanks that I have that are relatively leak free (at least for now): http://www.freestylephoto.biz/5041-A...ls?cat_id=1603

    Stainless steel tanks with plastic lids are pretty close to leak proof.

    The ones Freestyle sell are great. I recommend using Hewes reels. It's worth the extra cost.
