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. 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. What Size Tubing Do I Need?
