Question #1>

Hello Carolyn,

I just visited to your site to get some outdoor pond ideas. I
really like your great idea. I want to make similar style pond in
my backyard but I have couple Qs. such as;

1. How to take care for pond fish during winter time?

2. Beyond my backyard fence, there are plenty of Ducks flying
sometimes inside my backyard, How do I protect my pond fish?

I will be very appreciated if you will reply my two questions...I
will keep visiting to your site for the best result.

If the pond is deep enough, the fish should be okay for the winter
outside. You need to know what the frost line is in your area, how
deep it would freeze, so you can dig your pond at least one foot
deeper. If you are keeping koi, you may want to double that

Some people choose to bring their fish indoors and others simply
erect a covering to create a greenhouse effect conserving heat
inside for the pond. Then it doesn't actually freeze. Still
others install heating systems for their ponds out of gas or hot
water circulating heating systems. My own pond is nearly 7 ft.
deep and the frost line is 18".

As for the ducks, a good hunting dog might be a deterrent. Are you
in the United States? If so, they are protected by migratory bird
laws so you can't harm them if they come to call on your pond.
They are dirty and will even try to eat your fish. Again. a deep
pond and good filtration is the best defense for the fish. Two
ducks tried to land in my pond but when the two dogs ran out
barking they took off, never to return. Wish I could say the same
for the heron!

Question #2>

Hi Carolyn,

Wonderful site! I solved a very bad algae problem in my 800 gal.
pond, but the resulting green sludge left over has apparently
overwhelmed my filter capacity, and I can't seem to figure out how
to get rid of it. Is there a vacuum for such a problem? thanx., I
have baby Goldfish, and don't necessarily want to suck them up

My suggestion is to get a bigger filter to handle the gunk. In
order for your present filter to remove it you will have to do a
lot of maintenance, if you so decide. It isn't going to harm the
fish, but is unsightly.

You may use AlgaeFix and then add beneficial bacteria to restore
the balance to the pond. Shade the pond and do weekly water
changes - 25 % minimum - and you will probably have a nicer pond.
