I don't use a flux/degassing chem (yet) though have 2 types in transit
w/200lbs of petro-bond...
But I'm unsure of what difference they will make, as I'm casting out
of steel crucibles, and using a steel ladle to skim the dross. I
understand that this is a poor combination as it tends to intoduce
On the positive side, I did get 3 out of 5 larger pours to come out
very nicely using 16" deep boxes, and better compacion of the sand.

Also I'm getting some folks telling me that I should invest in a
Pyrometer, as the window of opportunity with to pour is far narrower
than one would expect... I found a place in Toronto that has them for
about $600 Cdn...
That is where the petro-bond and flux is coming from.
