Here is the deal. New pond owner, new to Pond Boss. Really enjoy the forum, and the knowledge gathered here. My situation:
I have a small (1/6 acre) pond. I am just looking for some fish for the grand kids to catch, and enjoy the water. The pond was built this year (2015) and is full, holds water well, and is 10' deep. When it was 1/2 full, I put 2# of FHM in. Three weeks later full pool, I put 44 6-8" CCs in. One was about 4#, got in some way

. I feed every day, CCs and FHMs come readily to feed. I have a little bit of structure in the pond, a 12' cedar, completely submerged, and 12 concrete cinder blocks. The minnows have spawned a couple of times, tons of minnows in there. My question: thinking about adding HBGs, as I can easily regulate how many I have in there. I am a little worried about spawning BGs taking over the pond. Really don't care to have bass, the pond is small, I want to keep it manageable.
If I put in HBG, how many? Couple dozen? I don't aerate, so I want to keep the biomass small.
I would welcome any thoughts or recommendations.
I have only tested my water for PH, it was 8.4. So far, all fish are doing well.
