Frequently Asked Questions
What is filter media density?
Filter media density refers to the weight of the media per unit of volume (e.g., kg per liter or lbs per gallon). Entering this allows the calculator to tell you exactly how much media you need to buy by weight.
Can I use this for both aquariums and ponds?
Yes! This calculator scales perfectly for any filtration system, whether it is a small home aquarium, a large backyard koi pond, or even a swimming pool sand filter.
Why is my volume result incorrect?
Ensure you are measuring the internal dimensions of the filter basket, not the external casing. The outer casing is often much larger than the actual space available for filter media.
