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.
