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.
tee, I have not tested for DO, were could I purchase a test kit? I'm new to this pond stuff, so I was only going off of what they told me. They were the original owners and lived here for over 30 years and the pond was dug when the house was built.
