If I may ask, what's the problem with very small leaks and by that I mean leaks that after the normal development time and n inversion agitation have not resulted in the critical loss of developer to the extent that the top of the film is exposed without total coverage by developer.

A few extra cc's of developer and fixer at the start will ensure that the film is always covered.

I really don't mind a little leakage but my tanks are all mixed up with non matching caps and all seem to leak a lot. One of them is so loose that if you don't hold the lid on it will fall off. I just think it's time for an upgrade.
