Stupid question time /sanitizing black water tank

Newbie here. Just bought a toy hauler and want to clean the black tank out. Only used it once so far and just dumped at the dump site. I don't have a clear hose or anything yet. there aren't any odors...

good advice about keeping water it during the summer but i would not leave it in there during the winter it would freeze and break the line or the valve or could even crack the tank
For the winter, it's about a half gallon of RV antifreeze or windshield washer antifreeze, whichever is cheaper. I don't want the tank to dry out, even in the winter.
