Background: Bought a dozer, built a 1 acre triangular shaped pond, 20'-0'in East Central Ia. in 1987. Watershed of 18 acres, grassland, now 15 years in 10 yr program. Home to beaver, muskrat, mink, turles, frogs, drowning deer and esp.200-300 migrating waterfowl, esp. ducks. They consequently brought everything ducks bring with them. esp snails. God only knows why, but I finally got around to stocking this pond 2 years ago-LMB,HB,Redears,Channels,Fatheads,Grass Carp,and on a pelletized feeding program. I aerate 24/7 with a 1/4 HP Gast pump in my openair barn, 800'away. I use 1/2" pipe,homemade diffuser, in 18' of water. Everything has gone very well except for-"question", finally-whew. Stocking those fish in a pond full of duck deposited snails was like puting a chicken in a penfull of dogs. My panfish are LOADED with yellow and black grub plus roundworm. I know, I know, cook em' good and eat em'. I aint, my wife aint, and my cat aint. (Have a friend who eats anything, maybe he will take em') DNR, who I trust as much as fish dealers, said they will "clear". Have I got a forever problem and just turn this pond into a swimming pool? Suggestions or comments, although not paid for, would be appreciated. Thanks-Postbeetle
