Hi all. Today I received an Omega stainless steel developing tank, marked Simmons-Omega on the bottom of the tank. It can hold 2 35mm reels or 1 120 reel. It came with 2 LPL brand 35mm reels. The tank has a steel lid or cover, not those black plastic or PVC ones. I plan to start using them either tonight or tomorrow. Before I do, I noticed some peculiarities & would like to ask: a) It seems that the tank's lid is quite loose. Being used to Paterson's Super System 4 & AP plastic tanks, I'm rather used to screwing the lid shut or pushing it down securely as with the Paterson. But with this Omega, there's no thread for me to screw down the lid. I just need to push the lid as far down as it will go and that's it. But, it just doesn't feel that secure. Same thing with the lid for the intake hole at the top of the lid, rather loose. Is this normal for all steel tanks? b) If I'm just going to develop 1 35mm film, then is it imperative for me to put in the other empty 35mm reel on top of the loaded one in the tank? I think so, if not the loaded reel would bounce around too much. It just seems...I don't know, weird to put in an empty reel. With the Paterson, the reel is put into a central core that keeps it from sliding up. Only 1 reel is needed. Would be glad if anyone can verify these for me. Thanks in advance.
