The pond liner we are told is PVC.
I have a pump which takes water from one end to the other and enters the
other end via a spray bar. the oxygen levels are ok. these have been
checked.
The pond is raised so we do not get any contamination from any outside
source like plant food.
We have not used any plant, grass food or any other chemicals on out land
nor have our neighbours for several years.
Currently I am trying three tests. A local koi specialist is helping he is
also at a loss at to what the problems may be. we are down to 3 things
firstly the liner and secondly the water and thirdly the atmosphere. he has
supplied me with 6 fish for the following
test 1, I have the pond which has only the liner water (my water) and two
gold fish.
test 2, I have a second tank which has a butyl liner, water (my water) and
two gold fish kept in side this is to check for the atmosphere
and the third test is a bucket of water with 2 gold fish (the water being
what the 6 gold fish have been supplied with, this water is known to be ok
for fish to survive in) this will also check to wee if there is a problem
with the atmosphere.
I will report back with the results

I have has a problem over the summer with plenty of dead fish. we have had
everything checked out even had pond doctors drink my pond water and
profess that they would stick their fish in that, when pressed of course
they didn't in fact put their fish in my water (so to speak) any way we
had to eliminate everything one by one right down to just the pond liner
and the water (difficult to test without the water) any way our fish still
kept dying. so we checked out just the water by putting fish in just a
plastic bucket. low and behold they live. SO WE HAVE A DODGY POND LINER
the suppliers recon there is nout wrong with it but as soon as you put a
fish near it the go all fins up.
Question has anyone else had pond liner problems?
What material is the liner made out of?
