Reclaiming a "Dead" Pond / Dealing with Ducks

Today's Pond Q&A

In this issue:

- Reclaiming a "Dead" Pond

- Dealing with Ducks


Question #1>

Hi Carolyn,

I am a subscriber to your newsletter and I appreciate your
common-sense approach to water gardening and the fish hobby. I was
wondering if I could get some advice from your many years of

I have a horrible eyesore of a pond. It's approximately 15ft wide,
30ft long and 4.5ft deep. It was built 30+ years ago to capture a
natural spring that flows out of the hillside and today it still
flows at about 20GPM.

In the first 28 years of its life it filled up with silt, algae,
and putrid black stinky gunk (a technical term no doubt). Then,
two years ago, I made it worse, I had all the gunk removed and it
seemed to make the problem worse! Not only did it start filling
back up with the putrid jet black gunk but it also has spongy white
rotting stuff that floats on the surface. My guess is that it is
rotting algae that came to the surface and is white because the
mineral content of the water is fairly high and it dries white
(like alkali on a field).

There is little life in the pond but I would like to reclaim it and
put fish in it eventually. To make matters worse, I have no power
near this pond so any solutions will have to be made either
manually, chemically, or with an alternative power source (wind or

Do you have any suggestions as to how to fix my eyesore of a pond?

I am also willing to send you pictures as well. Hopefully I can
get this pond the help it needs and we can do before and after
photos with your help.

Thank you for any advice or products you can provide.

Well, Microbe-Lift has done some amazing reclamation work on
polluted rivers in China and other parts of the world. I don't see
why PL wouldn't work in your pond. You should check the work they
did on the River Xiba which was able to have life return to it
after years of industrial dumping made it completely uninhabitable
for a very long time. Your pond certainly can't be worse than the
River Xiba.

I have also recently talked to someone in Hawaii who had no power
source and recommended them to a company in Florida (Aquatic
Eco-Systems, Inc.) that specializes in this type of situation.

One thing I might add to this, from what you mentioned, is that the
pond may need some sort of filtering device on incoming water to
prevent the immediate buildup of silt. You have a veritable delta
there. But if it runs IN at 20GPM, where does it run OUT? And is
it possible to erect a bog filter in the path of the water flow
to catch the silt? You may want to look into that.




Question #2>

Hi Carolyn,

What is the best way to keep a small backyard pond clean with ducks.

It is 17 x 11 and we have a bio-filter and the uv light set up but
the ducks are ruining it. I can not find plants that they will not
eat on me to help and to top it off I have almost direct sun.

Thanks for any help


Answer #2>


Ducks are such sweet things but such a dirty mess! And no,
there isn't any plant that I know of that they won't make a mess
out of. Like the name implies, duckweed can compete with them if
you care to introduce it into your pond. Otherwise, I would
consider the taller plants, such as Iris Pseudocorus, a more
suitable plant with ducks.

Are these pet ducks or wild ducks stopping by on the migratory
path? If pets, you will have to invest in a larger filter system.

Our Microbe-Lift products can clean a pond without chemicals.

You need to do 25% water changes weekly and consider heavier
filtration, and a skimmer to remove the feathers.

Finding frog eggs in a pond is a answer to your prayers, I discovered frog eggs in my pond 2 years ago and now have a nice population. They eat mosquetos and sing me to sleep at night.
