The four of us will use between 250-300 gallons in a normal day. Not meant to be critical of Tums at all, but I don't think I could ever get comfortable with using that volume of water to put in my recreational pond. The well over at the ponds will move 35 gpm, and I won't even let it run.

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.
