you are rushing things,let the water get wright and fish will bite,it takes time.i believe 100% your fish are in the pond.i've wrote 20 times on this site with my lake,can't catch a bass.when the water clears you will start catching them.i think(no pro )you are rushing things.i've caught more bass in the past 6 weeks than i have in the past 2 1/2 years out of my lake.guess what!!!my water was allways a off muddy color.my water finally got about 12"of vis. and the bite got 100 times better.i've added on too my pond several times over the last year and just when the water was getting fair i would flood the new section and the water would get off color and guess what 12 months of poor bass fishing.
