Help

I have a red wine in carboys plus some top off. The top off now
has a mold or bacteria layer on the surface. I was advised to make a
sulfite solution and spray in over the layer. I did that but with no
results. I then racked the two carboys (5 and 2.8g), cleaned the
carboys and checked the sulfites. The sulfites were at 50ppm so I put
the wine back into the cleaned carboys. Now both of them are beginning
to show a white film on the surface.
Any suggestions? This wine is an experimental for our organization
and I don't want to lose it.
Thanks in advance,
