Fedding a sugar wash: Bacteria problems?

[Vulture]

Hello all,
I tried searching for this answer but after 3 hrs found only tidbits.
If there is a thread that deals with this problem.... point me to it and my apologies.

I am on 2nd run of a WSSW started at 1.06 got down to 1.01 in 2 days so I decided to push it.
Added some sugar (in solution) and now the color of the wash has gone from a dirty blond color to almost brown...plus some funky white (Cheto's) looking things are floating on top.
Smell isin't bad but not as good as first run.....

Wineo says I can cover it loosly so I'm not using air locks...
All will be strip run then treated with baking soda for 1 week then spirtit run.
Just going for neutral spirits till I get some experiance under my belt.

Questions
1.) How do I know if I have a Bacteria infection?
testing..not just looks and smell
2.) Can I fix it?
3.) should I through it out?
4.) what is the easiest way to prevent one in the future?

thanks for your time and point me to a thread if I missed it somewhere.
At your service and your families too!

1) spots/stars/pinwheels, generally start in one place with "runners" attached .some are in the wash those you wont notice until to late.
2) run it, then wash everything good
3) see above
4) wash everything that comes in contact with the wash and sanatize,don't "peek"leave the open ferments to the fast ones (the ferments that take a few days)
some washes depend on bacteria/wiled yeast for flavor (like rum/sour mash) but if your doing a neutral you do not want it.
