Yes the former contracted service suggested carp and stocked a few 3 years ago. I've only seen one very large one in the pond since. Not sure if others got taken out by snapper or heron. I've seen a heron stab and then leave a 16" LMB. It was on the bank still alive and I assumed a kid had caught it and been dumb but it had a large piercing wound and I had just seen a heron there 10 mins before..
I'm not a chemical first type but I also don't want to be out there cutting and raking all summer. It seems to grow very fast.
As far as DO, again we have a lot of aeration and wind (always windy here in Nebraska) but I do worry more about winter and ice. We won't leave aeration on all winter as it will attract every goose in town. I was planning on leaving one diffuser and tubing in the water and could plug in the aerator if needed if we have thick ice/snow to open it up occasionally but not long enough for the geese to notice. A fish kill would be heartbreaking as we have caught up to 9.5" hybrid gills and plenty of 16" bass. I did a creel survey last year and 90% of the bass I caught all season were 15-16".
