Pond Calculators

Our pond volume calculators will help you quickly estimate how many gallons or litres our pond holds. 

Knowing the volume of our pond is essential when planning a pond build, replacing equipment, when treating for parasites, or rectifying water quality issues such as blanketweed treatments. Fitting the correct size filters and equipment from the start will save money in the long term. Having an accurate measure of the water reduces the risk of overdosing or underdosing pond treatments, reducing risk to your koi and improving the success rate of treatments.

If you have an irregular shape pond, we recommened you read our blog post, 5 Ways to Measure your Pond Volume.

We also have a calculator for pond liners if you want to use a flat sheet, or we also supply made to measure box welded liners.
