How to Clean Your Pond
Step VI - Acclimating and Returning the Fish (then Clean
The final step, once the pond is finally full of water again,
is to re-acclimate the fish to the pond and the new water.
The best way to do this is to drain out some of the water in the
holding tubs (10-20%) and replace it with some new pond water,
using your utility pump. Then wait for 5-10 minutes, and
Do this a few times, gradually increasing the percentage of
new water, to old pond water - until the water in the holding
tubs is almost entirely made up of new pond water.
Note: Observe the fish during this process, and
make sure that they do not appear overly stressed or try to jump
out of the tub. If there is something in the new water,
perhaps an over-dose of chemical de-chlorinator or similar, they
the fish don't like - you can usually tell by how they behave in
the tubs. Rapid gill movement, gasping at the surface, or
jumping out of the tubs is a sign that something isn't quite
right. However, this is rare - and usually you won't have
any problems following this method.
Note: The one thing you NEVER want to do is to
just toss the fish right back into the new pond water without
acclimating them. The stress this can cause on the fish
could kill them very quickly, or lower their immune system so
they are more prone to infection.
Once the fish are properly acclimated, drain the water in the
tubs down to 1/4 of the volume and then net them out, one by
one, back into the pond. By acclimating them as described above,
there shouldn't be any shock their system, and they will even
feel invigorated by a pond full of fresh new water!

That's it! You have now completed your first pond
cleaning. Now all that's left to do is clean up.
Rinse out your holding tubs, shop vac, pumps, waders, etc. and
pack away for next year...
Here are some great videos of the finished clean pond:
P.S. We recommend a thorough pond cleaning at least
once per year, preferably in Springtime. This is a great
time to remove all the organic waste that accumulated over the
winter, and will start decaying in the warmer weather.
