If you don't see your size listed, use the following formula for calculating the number of gallons of water you'll need. 

Round pool: Take the Diameter times Diameter, times the average depth, times 5.9. For example, for an 18 ft. pool 4 ft. high you would multiply 18 x 18 = 324. Then 324 x 4 = 1,296. Then 1,296 x 5.9 = 7,646.4 gallons needed.

Oval pool: Take the length times width, times the average depth, times 5.9. For example, for an 11' x 30' pool 4 ft. high you would multiply 11 x 30 = 330. Then 330 x 4 = 1,320. Then 1320 x 5.9 = 7,788 gallons needed.

Rectangular pool: Take the length times width, times the average depth, times 7.5. For example, for a 12' x 24' pool 4 ft. high you would multiply 12 x 24 = 288. Then 288 x 4 = 1,152. Then 1,152 x 7.5 = 8,646 gallons needed.
