Pond Size.
This means for a 2000 gallon pond you should be pumping AT LEAST 1000 Gallons Per Hour (GPH). Koi ponds need a higher turnover rate and the minimum is the full volume every hour. Larger ponds (over 5000 gallons) can start to decrease the turnover rate.

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?

How do I know what size water pump I need?

Measure the diameter of the fountain spout with a tape measure. You will be calculating the gallons per hour, or GPH, by multiplying the diameter by 100. For example, if your fountain spout is 1 inch in diameter: 1 x 100 = 100 GPH, your pump will need to be rated at 100 GPH.

Do I need to run my pond pump all the time?
