How we worked it out
Updated as you change the numbers.
- Volume = surface area × average depth × 7.48 gal per cu ft. Liner = length (or width) + 2 × deepest point + 2 × overlap.
Method and assumptions
Pond keepers commonly circulate the full volume through the filter about every 1 to 2 hours, more for koi.
Questions
How many gallons is a 10 × 6 ft pond 2 ft deep?
