Garden Pond Supply | Frequently Asked Questions


Garden Pond Supply routinely pools and collects frequently asked questions regarding Pond Supplies, Pond Kits, Pond Equipment in General and Pond Maintenance.

1. How deep should a backyard pond be?

It also needs to have an area of the pond at least 3 feet deep, 4 - 5 may be better. A water garden typically contains both goldfish and a variety of aquatic plants. Water gardens in moderate climates usually need for an area of the pond to be at least 2 feet deep

2. How much does it cost to put in a pond?

The average price to install a pond ranges from $1,177 and $4,910, with most homeowners paying around $3,039. The expense is usually $2.50 to $7.15 per square foot. For a larger-scale project, expect to pay $3,000 to $8,200 per acre, or more. Ponds can be surprisingly inexpensive to install.

3. How do you build a backyard pond?

To build a backyard pond, start by using a spade or excavator to dig out the pond so it's at least 7 feet by 4 feet across and 1.5 feet deep. Then, spread a thin layer of builder's sand over the bottom of the pond, and cover it with a pond liner that's at least 4 feet larger than the pond itself. Check out our "How to Build a Pond" Blog post that goes into deep detail that's easy to follow!

4. What fish are good for backyard ponds?

The Best Fish Breeds That Will Survive Winter in Outdoor Ponds
  • Archerfish.
  • Bluegills.
  • Fathead Minnows.
  • Golden Rainbow Trout.
  • Goldfish.
  • Koi.
  • Pumpkinseeds.
  • Redears.

5. What is the minimum depth for a fish pond?

You also need to think about what depth to make your pond. As a general rule of thumb, a pond should be 60cm (2ft) deep if you want plants and fish in it. Water that's too shallow is vulnerable to evaporating in warm weather and freezing in winter.

6. How deep should a pond be for fish to survive winter?

Generally 18 inches depth is sufficient, but ponds in extremely cold regions of the country should have areas 30 inches deep or deeper. Use a pond deicer to keep an area of the pond ice-free to allow toxic gases to escape. Some fish, such as fancy goldfish, should be brought indoors during the winter.

7. Do you need a pump in a pond?

Can You Have a Small Outdoor Pond Without a Pump? Pond pumps keep the water in a pond from becoming stagnant and help discourage the growth of algae. Additionally, pumps oxygenate the water, which is important if you hope to keep fish in your pond. Whether or not your small pond needs a pump depends on a few factors.

8. How deep should a 1 acre pond be?

Fish ponds should be at least 1/2 acre or more in surface area. Smaller ponds are suitable for some other uses. A popular pond size is 80 to 90 feet wide, 200 to 250 feet long and 10 to 12 feet deep.

9. Do outdoor ponds need filters?

In order to provide good water quality some form of waste removal must be provided. Two methods used in average water gardens and garden ponds are mechanical filtration, and biological filtration. Mechanical filters physically remove solids from the water by trapping the debris in some form of mat, brush, or sponge.

10. How much sun does a pond need?

Most books say a pond needs a minimum of 4-6 hours of sunlight a day for aquatic plants to live. They discourage building a pond in a shady area. The truth is that aquatic plants do bloom more and flourish better in high sunlight conditions.
