How Can I Tell How Many Gallons of Water are in my Pond?

There are a few times you might need to know how many gallons of water are in your pond, such as when figuring out how much of a certain water treatment product to use.

It's also handy to know how many gallons of water are in your pond so that you don't overstock your pond with fish​.

Some people will go through the process of actually metering the water going into their pond when they first fill it up. You didn't do that? No problem! There's a simple calculation that will get you pretty darn close:

​Length x Width x Average Depth x 7.25
​

No, it's not an exact number. For that, you'll need a more scientific process, like taking the time to meter the water going in. However, if you're keeping your pond organically, using bacteria and enzymes to control the water quality, this calculation will get you close enough. It will also give you an approximation for how many fish you can keep happy and healthy.
