I plan to add RES too I just left them out when I was typing my post. RC, do you have YP in your pond? If so how do they do?
I don't have anything against LMB I was just trying to have something different and avoid the management issues I've read about with LMB. If they would survive our temperatures I had also considered a few WE on a out and take basis but I don't know if they would do any better controlling the BG.
