This question is in reference to your article in the May/June 07 issue of PondBoss. On page 41, upper right paragraph beginning with optimal conditions, you mention "minimal turbulence".
Within the next week or two, weather permitting, I plan to muck out the stream that feeds my BG pond. The plan is to create a 20' x 30' x 8' mini pond. With the use of blocking nets, I would like to grow out some fathead minnows (free run) in addition to experimenting with raising some fish in cages. The plan calls for adding one 9" disk diffuser to foster water quality. The cage(s), will mirror the cylindrical ones shown in your articles. In your opinion, would the water movement caused by this diffuser exceed the limits of "minimal turbulence" creating a stress condition for the fish?
