Are you adding dye for aesthetics, or to help suppress plant growth? If limiting plant growth is the objective, research the dye and see what it claims in this regard. I know the aquashade does not mention aesthetics, but instead appears to focus on limiting specific wavelengths of light necessary for photosynthesis. I'm wondering if this might translate into reducing the amount of dye needed, in order to obtain the same degree of effectiveness.....no "tidy bowl" look???

"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.
