I've got a pond thats roughly 400-500 gallons. Plenty of fish(20) and
plenty of plants. the water is pretty clear but I'm beginning to get
concerned about too much sludge on the bottom, espescially with fall
around the corner. Does anyone have any tips on a good bottom feeder?
What happens to the waste from the bottom feeders?

You could try using a product like aquazyme. It is supposed to reduce the
amount of sludge build up, and apparently it does, because mine has little
if any. I've used it for about four years with good results. Another
thing you can do is to eliminate any leaves from entering the pond in the
fall by putting netting over your pond. I do this in the fall, and leave
it on until the last leaves have fallen and been raked up.
