Well said Paul.

Brad, the log book that Paul mentions will substitute for computer analysis using a program that really doesn't exist. With a log you go from a general feeling about the pond to a complete picture. Log what you see, what you catch and what occurs around the pond.

I would also identify the water quality. Make a disk out of the top of a white 5 gallon bucket or something. Poke a hole through the middle, run a piece of cord through and tie on a weight. Lower it into the water and see when it disappears. measure that distance. To be healthy and ideally balanced with a planktonic base, it ought to disappear at 18 to 24 inches.

I don't think I would add anything to an existing pond with what sounds like healthy fish.

Oh yeah, welcome to the show.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
