Enjoyed your homepage on ponds. I have a question. Did you use a liner
in your livestock tank? If not, I was curious if this had an effect on
the fish? If so, how much liner in you 6x5x3?
No liner. We have seen several ponds in metal livestock tanks with
healthy fish. The pond guy at the nursery recommended livestock tanks
for above ground tanks. We didn't even bother to find out if the
plastic tank outgassed something harmful to fish. I think I figured
that since it was ok for horses and cows, it would be ok for fish,
a doubtful conclusion at best. However, it has been more than a
year. Our fish have grown from dime (10 cents US) to 8 inch monsters.
Since we started with feeder goldfish, our fish investment was very low.
Btw, we have lost a lot of fish, but that is in ALL of our ponds, and
feeder goldfish have a very high mortality rate even in an aquarium.
I just added 2 koi to the big pond. I think that since the goldfish
have done so well, the koi should.
