How do I calculate my pond's volume?
Knowing your pond's volume is essential for choosing the right pump size, filter capacity, and dosing for water treatments or fish stocking levels.
For ponds with a consistent depth, simply measure length, width, and depth. For ponds with varying depths, use the average of your shallowest and deepest points for a reasonably accurate estimate.
Irregularly shaped ponds can be estimated by treating them as a rough rectangle or by breaking the shape into smaller sections and adding the volumes together.
