So run this by me, with a 'rotating tank' how do you do stand development if you don't know where the negative is in the tank in relation to the very small amount of developer?
I have for some time used all my Jobo tanks as "inversion" tanks. They come from the factory with a plastic cap, and they all have an "Inversion" spec. They can also be used with either the magnet or the cog lid on a jobo processor as "rotary" where the required amount of chemical is about 1/3 to 1/2 of that for "Inversion" To do "stand" processing, I would guess you would be reqired to use the "Inversion" amounts.
