Please Help Pond Fish Dieing

I have two large ponds, One pond is higher than the other (only
slightly) and runs into the other pond. There is then a pump that
takes the water through a filter then back to the top pond. My water
have been tested for Amonia, Nitrate and Nitite, and all read zero.
The strange problem is the fish is the bottom pond have started to
Die. They stop eating, stay at the bottom of the pond them come to
the top to dye, twitching and listing as they go. They look very
healthy apart from clamped fins. There are no visible parasites like
flukes or Ich. This is not the first time it has happened. last time
I think I stemmed it by adding salt or it may just be
coincedence(parasite / bacteria medications have no effect) it went
away so I restocked and now 5 months down the line I'm here again.
any ideas ? remember the top pond is never effected ?

MIKE

If another shows symptoms I would catch it and toss in a Q tank with new
water and see if it's the pond water that's doing it.

Have you checked your PH?

This was one of the first things tried. I have a large 440 ltr fush
tank that I filled with water from neibers pond wich is OK, and fish
still dies the same.

No visual symptoms apart from fin clamping.
No excess mucus colors, spots etc. look in good health.

The only thing I can come up with is maybe it is Costia ? although
there is no redness or gulping for air. but they do go off there
food, retreat to the bottom of the pond before comming up to die.
