Wondering why my goldfish died

Would your pond be an Aquascapes System pond by chance? That is the only
pond that I know of that it is recommended to power wash. If not an AS,
only clean as much as necessary to remove the debris from the bottom, as the
good bacteria live on the liner, in the fuzzy algae, etc, and you don't want
to remove all of that. If it is an AS, then you must power wash
periodically, or better yet, get rid of the rocks, and then cleaning is much
easier.

We have a pond in our backyard in Tennessee. We have had it for four
years. We had twenty goldfish and 1 catfish in it. It had become
very green with algae so we decided to clean it. We bought a
container to put our fish in while we cleaned it. We put the fish,
their current pond water, and the water hyacinth in the holding
container. We then emptied the pond, power washed it, and refilled
it. We added chlorine remover after we filled it. We added the fish
back to the water. Then, my husband added some algae blocker (blue in
color) to the water after the fish were re-introduced to the pond.
The next morning, all the goldfish were dead. We are wondering what
went wrong. Can anyone offer any suggestions?

pH shock, temperature shock, poisoning from whatever cleaner you used
for the
cleaning (assuming you didn't use straight water), ammonia poisoning (if
your
water treatment is chloramine instead of straight chlorine. Probably
other
possibilities -- it's almost always a bad idea to make "big" change to a
fish's
environment.



Thanks for the response. FYI - we used straight water to clean the
liner. Where can I find instructions on how to properly clean a fish
pond?

Thanks.
