There is still a widespread belief that SMB won't even survive in ponds. I tried to get a fisheries biologist from Purdue to come look at my pond because some of their educational material still indicates this. The professor said maybe they could visit sometime to see if I have special conditions that allow my SMB to thrive and spawn. He never did come visit, but perhaps due to the Covid-19 pandemic? Glad you all are providing current scientific knowledge to folks like me!
