B C. welcome to the Pond Boss Forum. Lots of information here and I would suggest spending some time looking through some of the older threads and archives for a lot of the answers to your questions. I am no expert and one should be around to help you out but my first concern in your pond would be the otters. The otter has harmed many a pond by removing most ALL of the fish and leaving you with little to nothing swimming in the pond. Be on guard when it comes to these fish eating animals.
