Pond needs

What do I need to know before making a pond?
I have a 15 gallon tank with 5 fish and they are all really small.  I know for a fact they are going to get really big so I was thinking about making a pound in out yard in a spot where there are no power or water lines and keeping the big fish out there and raising the smaller ones inside until they get big enough to go in the pond.  Keep in mind i'm only gonna make it 10ft long 7ft wide and the deepest part about 9ft.
Do you have any tips on a pond?


First of all, you don't need a pond 9' deep. Depending on where you live, 18" to 3 feet is usually deep enough. Your frost line (You can find out how deep your frost line is by calling your county extension service), determines how deep your pond needs to be. You will want to dig deeper than yours is.

I built a pond, now what?

First of all, you need to realize that a pond is a living breathing organism that needs little maintenance if it is started properly. If you obey the following 10 laws, your pond will be happy and healthy and in turn, make you the same.

1. You must have one bunch of anacharis (underwater grass) per square foot of water surface area. This serves as a natural filter and as food for the fish. It grows faster than the fish can eat it.

2. 50 - 60% of the surface of the water must be shaded with floating plants. Water lilies are great, as are water hyacinths, water lettuce or water poppies.

3. You must have fish to complete the balanced ecosystem. I recommend common goldfish. Do not put Japanese Koi in your pond. They will eat all of your plants...and they will do it quickly. If you have a koi pond, you have an outdoor aquarium and must treat it as such.

4. Do not feed your goldfish. EVER!! They will become too big for the pond and upset the ecosystem. You will have an overpopulation problem and eventually all of your fish will die. You may break this law, but if you do, you must have filtration in place.

5. Put in one linear foot of fish for each 25 square foot of pond surface area. If you have 100 square feet of pond, you may have 4 foot long fish, 8 six inch fish or 16 three inch fish and so on.

6. Do not allow turtles, crawfish, alligators, ducks, geese, dogs, raccoons or possums to swim in your pond.

7. Do not use chemicals!!! EVER! Add a dechlorinator when you first fill the pond and then when you add more than 10% water afterwards.

8. Do not worry about pH. It will take care of itself.

9. Remove any dead or decaying vegetation regularly so that ammonia does not build up and foul your pond.

10. Relax. Your pond will generally take care of itself. I recommend benevolent neglect as the best approach to pondkeeping.
