FAQs & Calculations to Help Select the Correct Kit

1. How Many Gallons of Water does My Water Feature Hold?

Rectangular Ponds

Length x Width x Average Depth x 7.48 = Gallons

Example: A rectangular pond 15’ long, 10’ wide and 1.5’ Deep Pond is...

15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons

Oval Ponds

Length x Width x Average Depth x 0.8 x 7.48 = Gallons

Example: An oval pond 15’ long, 10’ wide and 1.5’ deep is...

15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons

Round Ponds

Length x Width x Average Depth x 7.48 =Gallons

Example: 15’ long, 10’ wide and 1.5’ Deep Pond

15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
 

Streams

Length x Width x Average Depth x 0.25 x 7.48 = GALLONS =Gallons

Example: 15’ long, 10’ wide and 1.5’ Deep Pond

15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
 
2. How Big of a Pump Do I Need??
Minimum pump size is determined by pond type, water volume, head height and friction loss. The minimum pump size recommendations are:

Water Garden, Few Small Goldfish

Circulate total pond water valoume every 2 hours.

Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.

Fish Pond, Several Small Fish

Circulate total pond water valoume every 1 hour.

Example: 3,800 GPH pump for a 3000-gallon pond with 2’ waterfall.
 

Koi Pond, Several Large Fish

Circulate total pond water valoume every 3/4 hours.

Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.

Calculating Head Height

Dynamic head pressure is found by taking the vertical height of your waterfall; the distance between where your pump is (typically in the skimmer) and where your waterfall is, and adding the static head pressure (pipe and fittings) 1’ for every 10’ of tubing and 1’ for every elbow or “T” fitting.

Example: 3' (vertical height) + 2.5 (25' of tubing) + 2' (for 2 elbows) = 7.5' of Dynamic Head Pressure

Note:It is important to take into consideration while calculating how much flow will be at the top of your waterfall by accounting for the head height due to the laws of fluid dynamics. Please refer to the flow chart above to help choose the correct pump.
