In this section, we have added mostly everything we can think of that could benefit a pond builder or current pond owner.

Energy Consumption:

AMPS and Watts

For example, let's calculate the monthly cost of a 60 Watt light bulb used 5 hours per day:

60 Watts X 5 hours per day = 300 Watt hours
300 Watt hours X 30 days per month = 9000 Watt hours
9000 Watt hours / 1000 = 9 kWh
9 kWh X $0.14 = $1.26 Monthly cost to operate


So, look at your most recent energy bill and reference the "details of new charges" page. 

It should show you the kWh rate.  Mine is $0.04429. 

So a  260 watt pump running 24/365 = 260 x 24 (hours in a day) x 30 (days in a month) = 187,000 watts used / 1000 (kilowatts) = 187.20 Kilowatts x .04429 = $8.29 / month.  Can you afford to trade in your old pump now and save some money?  I think so!


 

Rock Calculations:

Quantity of rocks for use in a 2' deep pond:

  • Quantity of boulders used in pond (tons) = length x width divided by 65

  • 1/4" to 3" gravel used in pond (tons) = tons of boulders used x .045

  • Boulders used in a stream = 1/2 ton per 10' stream length

  • Approximately 3/4 - 1 1/4 tons of boulders are needed to build around the face of a 22" waterfall filter

Note:  Quantities of stone may differ depending on the type of stone being used.

 

 

RECOMENDED SIZE OF POND PUMP IS DETERMINED BY:

1) Turn Of Pond Water

• For a pond with a pressurized filter, turn the water approximately once every two hours.

(Example 1800 Gallon Pond - Miinimum 900 GPH Pump)

• For Ponds with skimmers and falls and most other types of ponds, water should be turned approximatly once every hour: (Example: 1800 Gallon Pond - Minimum 1800 GPH Pump)
2) Height Water Must Be Pumped Above Pond Surface.
 

THE CHART ABOVE

SHOWS HOW GPH DECREASES

AS THE HEAD HEIGHT INCREASES

• Head Height is the term for the vertical height the pump raises water above the surface of the pond.

• All pumps have a maximum head height (see Head Height Demonstration below)
 

3) SELECTING CORRECT TUBING IS CRITICAL TO PUMP PERFORMANCE

CORRECT SIZE TUBING IS VERY IMPORTANT.
• Too small of tubing restricts water flow. The example below demonstrates the importance of tubing size;

The image above shows three separate containers. Each collected the discharge from a 700 GPH pump for 10 seconds. The only difference is the tubing size. Too small of tubing will restrict the flow of water dramatically.

Use the chart below as a guide to assist in selecting the suggested tubing for each pump size. It shows the maximum flow rate for each size of tubing.
 

The LENGTH of tubing is also an important factor when choosing a pump.

EVERY 10’ OF TUBING EQUALS SAME RESTRICTIONS AS 1’ OF LIFT
