the blank tank flush port.

I didn’t do the black tank flush port — should I add some to it, even though I have a composting toilet?

Only if you don't want it to freeze and possibly burst.

Can I go ahead and add the Antifreeze and just drive with the Drain Valve open under the curbside and see if the SeeLevel monitor registers lower level when I arrive tomorrow evening at my first destination? 

 

I routinely drive with the fresh tank drain open if I want the tank empty at my next stop. It won't cause any problems.
