I think you're definitely short on forage if you want any larger bass, but adding forage after the fact doesn't usually provide the results hoped for.
It's like throwing the parachute out of the plane, and hoping it catches up with the absentminded skydiver in time for he or she to put it on and deploy.....problematic.
Ponds, especially smaller ponds, can be a handful when trying to achieve "balance" in the traditional sense. Not much neutral room, as it typically favors one gear or the other. I think supplemental feeding would help, but it's easy to suffer water quality and/or vegetation issues when you do.
For a small pond to provide sustained excitement for the family, I might consider a put and take operation (put, grow, and take?)
