How many gallons do I need for a 12 × 8 ft pond?
Answered by PondPro support
One gallon covers 40 sq ft and a 5 gallon pail covers 200 sq ft. Measure the whole wetted surface — floor and walls, not just the opening at the top. A pond that size normally works out at one pail plus one gallon, $525.25 all in, which is about $26 a year across the 20 year warranty. Put your measurements into the coverage calculator and it adds the right amount to your cart.
