Someone threw out a 50 gallon plastic container today,.......

...And it looks to me to be brand new and totally clean,...But I am
going to swab it down several times with white vinegar to clean it of
fungi, et cetera. But right now what I'm trying to do is mentally
trying to figure out just what get's moved to where, so that I then can
set up the grey-plastic container of treated tapwater that will weight
at least 415 pounds, minus the freshwater fish, et cetera when it's
filled up. Does anybody have any ideas, suggestions, et cetera?~Dean.
