Chris,
For a small station, using massive anodes is much easier than the nugget
aproach.
I use copper anodes which are 100 x 80 x 8 mm in size. I made a thread
into one of the sides and use another copper rod (also with a thread)
that goes into the anodes. I then moved a pvc tube over the rod and
sealed it on the bottom towards the anodes with PVC glue to avoid the
rod being used up by the plating process. You then can easily attach
wires to the top of the rod.
Be aware that at least Bungards starter kit is not evenly divideable.
That said some containers contain proportionally more of a given bath
(i.e. the predip) than others. So your calculation to divide it by 7
might be too optimistic. Can't comment on the one from MegaUK. Back when
I started, I also did so with Bugnard.
Putting the chemistry back into bottles is a good idea anyways. I also
do it this way for several reasons. It allows you to firmly keep it air
sealed, and also to place it in a dark and cool place all of which helps
to keep the chemistry alive over longer periodes.
