Maybe it depends on your goals for the pond? Swimming, fishing, a natural environment, or heavy on the management?

Dave nailed it, a clear pond is usually considered to be less fertile than one with a nice green tint about it. Aesthetically, I think most would like a clear pond. For the benefit of the pond and it's inhabitants, a bloom that limits visibility is often preferred.

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.
