external water pumps for Koi ponds
External water pumps are available in different electrical usages, and it's important to choose the right pump for your pond. Even though external water pumps must run 24/7 during the season, this is one component that should not be skimped on.
A simple formula used to determine monthly electrical costs for your
external water pump is:
Amps x Volts = Watts
Watts x 744 and divide by 1000 = KWH per month
