Closed w/bungs. I messed up by not moving fast enough...last week, he had barrels that had contained Lime juice. I understand that these were easy to clean.

This fellow had barrels and containers of all shapes and sizes. My attention was drawn to the big, square units, approx 4' cube(?)...external, metal framework, set on plastic pallets, with a large, screw on lid and a nice 2" bottom drain...also contained lime juice. He told me that these were selling to local people who were growing Tilapia, and the smaller barrels were used to build the filter systems...didn't know that anyone in my neck of the woods dabbled in aquaculture, but I may try and schedule a visit just to check their operations out.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
