Aquarium Water Volume Calculator
When buying a new fish tank, or, when considering whether or not you can add more fish safely to your current tank, it’s important to first know how much water volume your tank will hold.
We often get asked questions from our customers on this topic - and that’s because it’s extremely important for a number of reasons, including:
- Knowing how many fish you can safely keep in your tank
- Understanding how to treat the water with various dosages of chemicals
- Awareness of how often you should change or refresh the water to keep your fish healthy and happy.
To help you either decide on the size of aquarium you require, or to calculate whether you can home a brand new fish, we’ve developed a handy interactive tool, which allows you to calculate just how much water your aquarium can hold.
