Great now we have some of your goals we can focus on and discuss.
You said -
If I could do one of the ponds for looks and just use Koi and maybe CC, that would be neat too and I could feed once per day usually. Some times, I would have to go several days without feeding since I would not be home but I could find a feeder for them too.
Koi at relatively low densities per acre can cause the pond water to be muddy looking. Koi are ornimental carp and feed by actively and frequently rooting in the sediment for a variety of live and dead plants and animals (mostly invertebrates). I would not want more than 3 adult koi per 0.1 acre. Koi can easily grow to 24" to 30" long after a few years. When theese big fish root in the bottom lots of bottom sediment is stirred up into the water. More than 2 or 3 the water will get progressively more and more turbid and you will not be able to see the fish which is why most people stock them - to see them.
Koi will reproduce so you will need abundant predators to hopefully eat all the offspring. With 3 koi in 0.1 ac, stock 10 to 12 LM bass the same size as the koi. The water should stay fairly clear, water visibility 2 to 4 ft and the bass should keep the young koi to a minimum. I make no guarantees.
If you want relatively clear water in one small pond, just put 8 - 10 small (4"-6") LM bass or smallmouth bass in the pond and basicaly forget it except for plant control. The bass will keep practically all the bugs, frogs, and water critters cleaned up. The bass will only grow to 11"-13" inches long. The bass will usually spawn each year and keep the young eaten up. Occassionaly a couple young bass will survive, especially if weed cover is present. The pond will be basically stable and critter free with as clear of water as surrounding conditions will allow. A couple koi in this situation would be okay, however the water would not be as clear as if no koi were present. In several ponds around me with this bass ONLY stocking, the water clarity is around 4ft to 6 ft deep or more year round. They use some Aquashade dye to help with weed control.
PS.You could also put 4 to 8 channel catfish in the pond with the koi and bass. With those 3 species, and when koi and CC are larger, my guess is water clarity will be about 2ft most of the summer. If the pond becomes weedy then you will have trouble with koi overpopulating. Rooting of Koi may keep weeds to a minimum.
If you don't put any fish in the clear pond it will stay pretty clear but it will have an abundant bug / frog community which is okay with some owners.
You can also raise just fathead minnows or shiners in the one pond and use them to feed the predators in the other pond.
Experiment. You can easily start over.
Choices - choices, many choices and options.
