Hi,

The small arcing is a common problem with Al taped toroids.  If you dont
like it, the easiest way of stopping it is to use some conductive adhesive
CU tape on the inside diameter (top or bottom) of the toroid to short all
the pieces together.  This way, the copper can be hidden from view (mostly).
You dont need to redo the toroid nor use a large amount of CU tape, just
enough to short the segments of AL tape together.

Or..... you could just ignore it.  the small arc doesn't effect anything.
My toroid does the same thing and I get 74 inch arcs with a 1000 watt coil.
