CALCULATIONS FOR ROCK USED IN PONDS,
WATERFALLS & STREAMS
Rock Calculations for the POND
Length x Width / 40= Tons of boulders
***Using a 1:2:1 ratio***
For every (1 ton) of 6"-12" rock, get (2 ton) of 12"-18" and (1 ton) of 18"-24"
rock
Quantity of Boulders used in a STREAM
For every 10' of STREAM = (1 1/2 ton) using 1:2:1 Ratio above
Quantity of Gravel used in the POND
Pond grave=30% total tons of POND boulders
Quantity of Gravel used in a STREAM
Stream gravel=30% total tons of STREAM boulders
Small MicroPond / D.I.Y. Rock Calculation for the POND
Length x Width / 65 = Tons of boulders
Small MicroPond / D.I.Y. Quantity of Boulders used in a STREAM
For every 10' of stream = (1/2 ton) 6-12" & (1/2 ton) 12-18"
Quantity of Boulders Used for the FACE of the BIOFALLS
Mini / Signature BIOFALLS filter = (1 ton) will cover the face of the falls
Standard BIOFALLS filter = (1 1/2 ton) will cover the face of the falls
Grande BIOFALLS filter = (3 on) will cover the face of the falls
Quantity of Stone Used in the A.D.I. Pondless Basin
Length x Width x Depth = Cubic Ft.
...90 lbs of rock per (1) cubic foot (4-6" and/or 1 1/2-2" rock)
...Minimum 40% of 4-6" rock, 60% of 1 1/2-2" and then any additional
decorative gravel for on top
Quantity of Stone Used in a MicroPondless Basin
Length x Width x Depth = Cubic Ft.
...90 lbs of rock per (1) cubic foot ( 1 1/2-2" rock only)
Quantity of Stone Used around the perimeter of the Basin
(1/2 ton) 6-12" stone will cover 20 linear feet of edge
(1/2 ton) 12-18" stone will cover 5 linear feet of edge
Quantity of Stone Used in a WETLAND FILTER (PER 10FT)
750 lbs 4-6" river gravel
900 lbs 1 1/2-2" river gravel
900 lbs. 1/2-3/4" river gravel
RETAINING WALLS
Quantity of Boulders Used for Retaining Walls
(1 ton) of 12-18" size rocks will cover about 10 linear feet
(1ton) of 18-24" size rocks will cover about 5 linear feet
NOTE: THE AMOUNT OF ROCK QUOTED ABOVE IS BASED ON GENERAL
FIELDSTONE. THIS NUMBER MAY GO UP OR DOWN DEPENDING UPON
YOUR SELECTION OF ROCK AS SOME ARE MORE DENSE THAN OTHERS.
GALLONS OF WATER
Approximate Gallons of Water in a Pond
Length x Width x 80% x Avg. Depth x 7.48= total gallons
(example: 11 x 16 x .80 x 1.5 x 7.48= 1579)
Approximate Gallons of Water in a Stream
Length x Width x .25 (depth) x 7.48 = total gallons
Approximate Gallons of Water in a Pondless Basin
Length x Width x 80% x Depth x 2.2= Gallons in the basin
***you need 2 x the amount of water in your basin***
ELECTRICAL CONSUMPTION / CONVERSION
Amps x Volts / 1000 x .10 (kw/per hour) x 24 hours x 30.4 days = Monthly cost
Watts = volts x amps
Amps = watts / volts

| DON'T FORGET THE PLANTS & FISH Suggested Plant Quantities Plants are one of the 5 essential ingredients to a healthy pond ecosystem. Here are suggested number of plant for the most common pond system sizes. 4 x 6 1 lily, 5 marginals, 8 floaters 6 x 8 1 lily, 7 marginals, 8 floaters 6 x 11 1 lily, 7 marginals, 10 floaters 8 x 11 1-2 lilies, 9 marginals, 10 floaters 11 x 11 2 lilies, 9 marginals, 12 floaters 11 x 16 2-3 lilies, 11 marginals, 12 floaters 16 x 16 3 lilies, 14 marginals, 20 floaters 16 x 21 4 lilies, 17 marginals, 23 floaters 21 x 21 4-5 lilies, 21 marginals, 25 floaters 21 x 26 5-6 lilies, 27 marginals, 27 floaters 26 x 26 6-7 lilies, 33 marginals, 30 floaters NOTE: You will need more marginals for a streambed SUGGESTED FISH QUANTITIES Fish are another essential ingredient to a healthy pond ecosystem. Here is a standard formula to use in calculating the approximate number of fish to include in your pond, although there are a few variable (ex. size of pump, quantity of plants, etc) ONE INCH OF FISH FOR EVERY SQUARE FOOT OF POND SURFACE AREA. For example: a 10 x 10' pond has 100 square feet of surface area. This means that the pond could support 100 inches of fish. This 100 inches could b on 100-inch fish, 2 50-inch fish, four 25-inch fish, eight 12.5 inch fish, or...you get the picture. |
