Facts and Formulas

• To determine the surface area of a rectangular pond:
  Length of pond in feet X Width of pond in feet = Surface Area (sq. ft.)
• To determine the surface area of a circular pond:
  Radius of pond in feet X Radius of pond in feet X 3.14 = Surface Area (sq .ft.)
• To determine the volume of a pond in gallons:
  Surface area of the pond (sq .ft.) X Average depth in feet X 7.5 = # Gallons
• To determine the amount of liner needed:
  Maximum width(ft.) + Twice the maximum depth(ft.) + 2 ft. = Width Needed
  Maximum length(ft.) + Twice the maximum depth(ft.) + 2 ft. = Length Needed
• To minimize water quality problems, we suggest stocking no more than 1” of fish per cubic foot of water (53 cubic feet = 8-10 fish, 4-5” in size).
• Filter pumps should circulate the pond every 2 – 4 hrs. Effluent type (solids handling) pumps are best for filtration.
• To estimate water volume required for a waterfall or stream, use the basis of 100 GPH per inch of width (1200 GPH for a 12” wide waterfall). This provides a minimal (+/- ¼” deep) sheet of water. For a “heavy” flow and for streams, multiply this figure by 2, 3 or 4. Be sure channel edges are high enough to contain this water flow.
• Pump flow rates, using flexible, non-kink tubing as large or larger than the pump’s outlet, are determined by the VERTICAL lift. Measure from water surface in the base pool to the highest point of outlet.
• To maintain a healthy natural balance in a pond:
  • use one bunch of oxygenators for every 1-2 sq .ft.
  • cover 60% of the water surface with a combination of water lilies, floating plants, such as hyacinths and marginal plants.
  • Add one Japanese Trapdoor Snail for every 1-2 sq .ft
