Fishkeeping often requires a bit of maths; the links below give aquarium calculators for a variety of things that you might need to work out during your fishkeeping. Simply click on the link required and enter your details into the boxes. The calculators will do the maths for you.
You’ll notice we don’t have an aquarium stocking calculator, that’s because there is no ‘one size fits all’ when it comes to stocking your aquarium, there are many variables to consider. You might like to have a read of our article about understanding fish stocking guides for more information.
