Maybe it just depends upon one's level of involvement. Sometimes, good enough is just that..... good enough.

"Do regular BG have the ultimate potential to outgrow HBG?" ...... Yep. Will that matter in the majority of 1/2 acre backyard ponds under minimal management? No? Maybe?

"Will stainless screws last longer in my dock than regular screws?"...... Yep. Are you building the dock for you, to enjoy during your lifetime, or is it to be a monument for the ages, marveled at by curious visitors 300 years from now?

"Is feeding higher quality, more expensive fish food better for my fish and my pond?"...... most likely. Is growing quantities of BG to one pound plus on cheaper feed with minimal expenditure acceptable? Yes? Maybe?
