Not sure how much faith I have in uneaten feed on the bottom being no big deal? If you can't watch the fish feed, how do you know if they're eating at all? How do you know how much to throw out? I keep envisioning a scenario wherein a pondowner just throws sinking feed, day after day throughout the winter months. Sounds like a scenario for a pond bottom carpeted by fertilizer to me.

Of course, if that happens, they will probably be happy to recommend ($$$) a treatment option.... wink

"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.
