Hi Mike, welcome to the forum.

What makes the former owner believe the DO levels are low? Have you tested the DO levels yet? I recommend you doing so prior to making a lot of other pond management decisions.

If a pond supports adult BG, it will most likely also support other warm water fish, such as LMB.
