I posted this on nothing to do with boats but i want to give it maximum exposure. I am in the process of purchasing a new home with a pond/lake Man made 1 1/2 to 1 3/4 acres. It is now in good condition and i want to maintain it like that. It has bluegills, and large mouth bass and a couple of grass carp/. i would like to add a few catfish to it also. I do not know if i need to treat this pond with someting or just leave it alone.any suggestions will be appreciated or if you can tell me where i may find information on maintaing this pond.
