# What size pond 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.

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.

Beside above, what size pump do I need for my koi pond?

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.

How do I calculate the waterfall for my pond pump?

To determine the GPH/GPM needed for your waterfall or stream – multiply the width in feet x 30 GPM. Example: To build an “average” waterfall 3′ wide and 10′ high above the pond – multiply 3′ (width) x 30 GPM which equals 90 GPM or 5,400 GPH at 10 feet of head.

### 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.
