Welcome to the forum Lsutgrfan!

Let's see:

Wants big BG....
Relatively small BOW...
Available to feed.....
Desires HSB...
Likes to eat BG....

I know what I'm thinking, but it's too early to throw it out there without some more info. I agree with the others, you need a better idea of what you have now in the way of fish, and pond depths. Are either of these ponds fed by another water source?

"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.
