So hydrothol 191 keeps planktonic down well, even in large lakes? Cost is a big issue on this one, but I'll do it if it works. I like it in small ponds and trout/koi ponds. I'm gathering from my research that locking up the phosphorus is about out of the question. Math-wise i just like seeing any differing views to hopefully learn more. Just want any sites or info for calculating systems
