How to Clean Your Pond
Step III - Clean the Filter, Skimmer, and Start Cleaning
While your pond is draining is also a good time to go ahead
and clean out your filter. Filters can in a wide variety
of different sizes and styles, so use your own common sense when
cleaning these out, depending on which type of filter you have.
Submerged filters should be removed and rinsed off, cleaned
of any debris that may be in clogging the water flow, sponges
rinsed, and pump cleaned. It's also a good idea to remove
the impeller cover and rinse out the impeller area as well, if
you can get to it.
External biofilters should be back-flushed and the pump
basket cleaned out, and rinsed if necessary.
You can also use this time to clean out the skimmer if you
have one. It's better to get these items out of the way
while the pond is draining, so you don't have
to worry about it later.

Now, once the pond water starts to drop to below 1/2 way
down, you can start scrubbing or power washing the sides.
Now here's where some of you may disagree with how we are
doing this... 'Natural' pond owners especially.
It's true that there are a variety of beneficial
bacteria and organisms that serve to balance the pond naturally
which will be disturbed by this type of aggressive cleaning...

However, if you have a properly sized biological filter
(which every pond should have) then this is really not all that
important because your beneficial bacteria and ecosystem lives
in the filter.
Note: When cleaning out biological filters, especially
submerged bio-filters, it's best to clean them using water from
the pond, and not hose / chlorinated water which will kill the
Once you clean the sides and the water level starts to get
your discharge pump will likely start to have trouble pumping out the rest
of the water, because it's getting clogged by all the debris and
muck. Even with a pump protector basket (recommended), the
pump will only be able to pump out so much of the dirty water.

Now it's time to set up your Shop Vac (the bigger the
better), and get ready to vacuum out some sludge!
