LINER CALCULATIONS:
Length = (Maximum Depth x 2) + Maximum Length + 2 ft.
Width= (Maximum Depth x 2) + Maximum Width + 2 ft.
Example: An 8 x 10 x 2.5 would require a 15′ x 17′ Liner
POND VOLUME CALCULATOR Average Length x Average Width x Average Depth x 7.48
Example: A 12 x 10 x 2 foot depth would be 1795.2 Gallons
ROUND POND CALCULATIONS Radius Squared x 3.14 x Average Depth x 7.48
Example: 10′ round pond 4′ deep would be 2480 gallons
FISH CALCULATIONS
First determine surface area of pond (Length x Width) or Area of circle for round pond (3.14 x radius squared).
To then determine how many fish: 1″ of fish per sq ft of surface area is safe; 2″ per sq ft would require testing water weekly for nitrites, ammonia, and pH; 3″ or more per sq ft requires testing and bio-filtration.
PUMP SIZE Total gallons of pond divided by 3 = Minimum pump size for filtration only. Otherwise pump volume should be determined by the feature to be created.
ELECTRICITY CALCULATIONS
Watts per hour divided by 1000 = Kilowatts per hour
Kilowatts x 0.10 = Kilowatt dollars per hour (KWDH)
KWDH x 24 = Kilowatt dollars per day (KWDD)
KWDD x 30 = Kilowatt dollars per month
KWDD x 365 = Kilowatt dollars per year
OTHER USEFUL CALCULATIONS
Total weight of water = Total gallons of water x 8.5
Total tons of stone for edging pond = Total surface of pond (length x width) divided by 65
