# UPDATED!! HOW MANY GALLONS OF WATER DOES MY KOI POND HOLD?

## You should know the answer to this very important question

###
**UpDated!!** Here’s how to calculate the **EXACT** number of gallons of water in your koi pond hold?

In order to help you with your koi or koi pond problems, I must know the amount of gallons in your koi pond. I’m very surprised of how many pond keepers just guess at the answer to that question. Guessing can cause death by over dosing or not giving enough pond treatment to cure the koi health problem which also can cause death.

### Here are some simple formulas you can use to determine the gallons of water in your koi pond however, they are not as accurate as the Updated formula above:

- Each cubic foot contains 7.48 gallons of water.
- This is the formula you use if your pond is a Square or Rectangle:
- Length x Width x Depth x 7.48
- If your pond has straight sides, no plant shelves, this formula will give you the exact number of gallons in your pond.
*Example: 8 feet wide and 15 feet long and 4 feet deep the total gallons would be exactly: 3,590.4 gallons.*

### This is the formula you use if your pond is a perfect Circle:

- Radius x Radius x 3.14 x Depth x 7.48
*Note: the Radius is half the Diameter (distance across the middle of the pond)*

If your pond has straight sides, no plant shelves, this formula will give you the exact number of gallons in your pond. *Example: A round pond that is 4 foot deep, 20 foot wide (20 ft. Diameter or a 10 ft. Radius) calculation would be 10 R X 10 R X 3.14 X 4 X 7.48 the total gallons would be exactly: 9,394.88 gallons.*

### This is the formula you use if your pond is an Oval:

- Radius x Radius x 3.14 x Depth x 7.48
*Attention: the formula will look the same as a circle however the two radius sizes will be different.*

If your pond has straight sides, no plant shelves, this formula will give you the exact number of gallons in your pond.*Example: An oval pond that measures 20 ft. (20 ft. Diameter or a 10 ft. Radius) one way and 10 ft. in diameter (10 ft. diameter or a 5 ft. radius) the other way and 4 ft. deep. The calculation would be 10 R X 5 R X 3.14 X 4 X 7.48 the total gallons would be exactly: 4,697.44 gallons.*

### Irregular Shape Ponds:

Average Length x Average Width x Average Depth x 7.0

- It is very difficult to figure the EXACT gallons of an irregular size pond. Average measurements must be used. Many Pond Keepers will use 7.0 gallons per cubic foot instead of 7.48 to compensate for large rocks and round corners. Plus, it’s important to average the depth of the pond. A pond that is 3 foot in some places and 5 foot in others should be figured as an average of 4 foot.
- Pond Calculators can give you the correct answer to the amount of water in a perfect square, rectangle, circle or oval straight side pond, however when it comes to the irregular shape ponds, your accurate, average measurements are very important in determining the number of gallons in an irregular shape pond.
