Similarly, what size pump do I need for my pond?
The pond pump should circulate the water at least once per hour. To determine the volume of your pond, multiply the length x width x depth. For every square foot of volume there are 7.5 gallons of water. So, a pond that has a volume of 50 cubic feet will contain roughly 375 gallons of water.
Furthermore, what size filter do I need for my koi pond? The rule of thumb is that you should have a filter that is rated for about 1.5 times the number of gallons in your pond. So if you calculated your pond contains 400 gallons, 1.5 x 400 would mean a filter rated at 600 gallons per hour (gph).
People also ask, what size pump do I need for a 300 gallon pond?
Larger volumes need larger pumps. To figure out the volume of a pond or fountain in gallons, multiply its length by width by average depth (all in feet) by 7.5. For a 300-gallon water feature of a type (explained below) that requires water circulation every two hours, you'd look for a pump with a flow rate of 150 GPH.
What size pump do I need for 125 gallon pond?
Minimum Size To determine pump size multiply GPH by 0.5. Thus, minimum pump size for a 250-gallon pond is one rated at 125 gallons per hour.
