Thanks for your comments guy's this really helps me out, please keep them comeing!!!! So you think I should add how many LMB to help controll BG? I was hopeing the HSB would help control the bg when they were in the 1/2 to 2.5 inch range. I am bery excited to get this project started, I have always wanted big gills and perch in a pond, Along with the walleye and the HSB. So what would you reccommend for areation for the pond? I have read some on this, Although I don't think in laymonds terms I have grasped it yet, but what I am getting is it will circulate the water colum while adding oxegen, but I thought their would already be plenty of oxegen in the pond with out it, so I guess I really want to know the huge benift.
