Okay, I know Jobo meant well with their number coding system, but for a newcomers it can be enough to do your head in... I have a CPA-2 which came with more print drums than any sane person would consider normal, but no film developing tanks. I managed to get a stack of Jobo UniSet 2001 reels at my local (real) photography store, for so alarmingly cheap that I left in a hurry before they changed their mind, and now have the issue of finding a tank for them to go in. I don't have a lift attachment, so I also need to have the magnet base for whatever tank I end up with. The box for the Uniset reel suggests they're for "2000" series tanks. Does this mean they fit in the 25** series tanks? I thought I should be absolutely sure before I buy a tank off eBay and find out I have a bunch of reels that don't fit in it... I'm looking at the 25** series tanks because I also shoot 4x5" and would like to process that one day too. A lot of tanks out there come with the cog lids. Can I use the tank with the magnet base with the cog lid without a cap, or will they leak fluid or light in that configuration? Thanks for your help, folks...these both seem like really obvious sounding questions, now I've asked them, but better safe than stupid.
