Tums- They are in both of my ponds (1 acre and 1/4 acre). For my goals and uses of the ponds, I am very happy with my choice of BCP. My orginal goal was to create a sustainable population of 10-12" /.5-1 lb BCP. They are where I want them as far as numbers and sizes. The question is can I keep them there and for how long.

Side note: We just received .5" of rain yesterday. The first rain my ponds have received since July!! The worst drought on record for my location. When your pond drops 30% of its water and freeze up is coming fast, a man starts to be concerned! I sure hope I don't have to start over.
