    I have been developing film for many years now, but I have never given the agitation stick on the Paterson tanks much thought. Is the tank light tight without it?

    Yes the tank light tight without it. I use inversion agitation rather than the agitation stick.

    Yes, it is, and just to balance the argument I only ever use the twizzel stick to agitate the film.

    Sounds good. I have been pouring the developer into the tank all the time with the stick stuck on. Takes about forever. But last time I tried and left it out while I poured stop into the tank, and hey, we are now talking warp speed... :D

    The only time I ever used it was for giving the film a twirl now and then when fixing and HCA'in the film. (Yes, I know that it should be "constant agitation", but I'm sometimes lazy. So... the Jobo CPP2 comes in really handy. :smile: )
    I havn't heard of anyone else using that stick either. Inversion is so much better.

    If you happen to have a tank that leaks when inverted, the stick is a lot less messy :smile:.

    They work pretty well, if you alternate between twisting the stick and moving the tank back and round and round on a flat surface.

    I never use it. It just feels funny.

    I have never seen any differences in my film developing if I use the stick or I invert

    Its a personal choice thing

    I tend to invert - most of the time

    I find the stick a little too short to comfortably use/hold for extended times

    On the other hand using the stick helps prevent getting developer all over your hands - dev really stings when it gets into cuts and cracked skin
