How many GPH does a pond pump need?
How many GPH does a pond pump need?
A good rule of thumb is that pumps should be able to pump out about half the pond volume every hour. For example, a pump that moves 500 gallons per hour would be appropriate for a 1,000 gallon pond. You don’t have to refer to a fountain pump size chart to figure out the best water pumps for your garden.
How many GPH do I need for a pond waterfall?
Flow Rate: The average amount of water moving over a waterfall is 1,500 GPH for every 1′ of width. Therefore, a waterfall that is 2′ wide would need a 3,000 GPH pump. If you are looking for a heavier flow, calculate your flow using 2,000 GPH per foot.
What size pump do I need for my fish pond?
It is recommended that pond water is circulated at least once per hour. For example, if you have a 500-gallon pond, you need a pump that runs 500 GPH at the height of the discharge. This is true if it also has a skimmer or waterfall.
How many GPH do you need for a water feature?
Water feature volume. 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.
How many gallons is my pond calculator?
Calculate approximately how many gallons of water are in a pond. Average length x Average width x Average depth x 7.48 = Total gallons.
Can a pond pump be too big?
A pond pump can be too big for the size of pond, causing excess water loss, increased energy usage, an uncomfortable noise level, and an unsuitable environment for plants or fish. Careful calculation of your pump needs before purchase will help to avoid future difficulties.
What is GPH in water pump?
Commonly measured in terms of either gallons (1 gallon = 3.8 liters) per minute (GPM) or gallons per hour (GPH), the flow rate describes the amount of work a pump performs. Some pump manufacturers also include a horsepower rating.
How do I calculate the volume of water in my pond?
Use our handy calculator to work out your pond capacity.
- The easiest way to do this is to measure the length, the width and the depth of your pond in feet.
- Once you have all three dimensions, you need to multiply these all together and then multiply this calculation by 6.25.

How do you calculate gph pump?
For example, consider your pump is able to fill the gallon container within 15 seconds. Divide the timed rate by 60 to find the gallon per minute rate: 60 divided by 15 equals 4. Multiply the gallon per minute rate by 60 to find the gph rate: 4 times 60 equals 240 gph.
How big is my pond in gallons?
Multiply the length by the width by the depth to get the volume in cubic feet. For example, if your pond is 16 feet long, 8 feet wide and 4 feet deep, multiply 16 by 8 by 4 to get 512 cubic feet. Convert cubic feet to gallons by multiplying the cubic feet by 7.48.
