Seasonal Maintenance Tips
WINTER
Once the water begins to freeze, you need to keep a hole in the ice over the winter to prevent the gases in the pond from building up and killing the fish. This can be done by one of  several methods:
  • If your waterfall doesn't splash much, you may be able to leave it run all winter.
  • Using a small pump in a shallow area to keep the water moving at the surface so it doesn't freeze. Keep it in shallow water (8" - 12") and minimize splashing at the surface.
  • Use a large size aquarium or pond bubbler to do the same as above.
  • There are also some floating de-icers that achieve the same effect as the two points above.
  • Use a pond heater. Perhaps you may want to put a timer on the heater. (for 1-2 hours a day).
  • If the ice freezes over totally, don't chop a hole. Use a bucket of hot water to melt the ice.
  • In the winter, the warmest water is at the bottom. That is where the fish will stay. Don't put a pump or bubbler on the bottom - it will make the water even colder.


Frequently Asked Questions
The following are a few of the more common questions asked by people considering having a pond put in.
  1. How big or small can it be?
    • As big or small as you like. However small ponds tend to be harder to keep balanced. Our average size for pond installation range from about 8' - 10' x 12' - 16'
  2. What about pre-formed ponds versus liners?
    • Pre-formed ponds are generally smaller and too shallow (18") to keep fish over the winter. As pre-formed ponds gets larger they are as expensive or more money than the liner type ponds.
  3. How deep does a pond have to be to keep fish over the winter?
    • We recommend that an area of the pond (not too large) should be about 2.5' deep, but the rest of the pond can be 2' or less.
  4. How big a pump do I need?
    • The rule of thumb is to be big enough to circulate the volume (gallons) of water in the pond once every 1-2 hours, more towards the 1 hour mark.
    • Other factors to take into account are how high the waterfall is, and the distance to the waterfall. Also you need to think about whether you want a "Babbling Brook" or "Niagara Falls" or somewhere in between.
  5. How do I determine the number of gallons of water in my Pond?
    • Average length x average width x average depth = _ cubic feet _ cubic feet x 7.5
      U.S. gallons per cubic foot = _ gallons in pond (approximately).
  6. How do I know how much liner is needed?
    • Longest length and width plus about 7 feet (2 ½ ' to the bottom plus 2 ½ ' up the other side plus 1' extra at the edge on each dimension. Example: 10' x 13' pond needs about 17' x 20' liner.
  7. Can I have the pond in full sun or largely shade?
    • Yes, and yes, it just takes proper design work and you can have a pond anywhere on your property.
  8. Do I need to put anything in the water?
    • Yes, you need to put water conditioners in the water to help establish and maintain a balance in the eco-system of the pond. This is especially important to do in the spring.
  9. How much maintenance does it take?
    • A properly  designed pond and filtration system should only require about 15 - 20 minutes of maintenance per week.
  10. How often does it need to be cleaned out?
    • Once established, we recommend an annual cleanout, usually in the spring.
  11. Can I have a waterfall or stream without a pond?
    • Certainly, it is called a disappearing waterfall and /or stream. These are great where you don't want the maintenance of a pond, or where you have concerns about your toddlers. We can also create your own unique water feature such as a "bubbling stone" or use your imagination for a "container" feature of your own design.
  12. What about indoor water features?
    • Yes we do indoor features, and we can help you with various types of unique container features or a "water wall".
