No ich, no flashing, the poop that I have seen looks normal.
The way I have to do water changes is crazy. I live on the river. Our water comes from the river, so it's full of chemicals. I draw the water from the hot side and let it sit over night. I boil water to heat it to the tanks temp and I add Prime to the buckets. I even wait 15 minutes in between buckets to let the fish acclimate.
