We have broken each calculation up into Minimum Requirement and Recommended Amount of Pond Pack to use for your pond.
One box of the various Pond Conditioners that make up a Pond Pack treats a ¼ pond with an average depth of 4-6 ft for 1 season at a cost of only $ 199.00. About ½ what the costs are of a typical Pond Chemical Solution Pack.
Once you know how many acres your pond is then it's easy to order the number of Pond Packs recommended.
Simply measure the distance around the pond in feet and then multiply this number by itself - divided by 547,390. Eg. A Pond 400 ft around would be (400 X 400 = 160,000/537,390 = .29 acres) - just over 1/4 of an acre.
For ponds that are square, rectangle or irregular in shape you compute the surface area of the pond by measuring the width by the length of the pond dividing it by 43,560. Eg. A pond 110 ft long by 150 ft wide would be (110 * 150 = 16,500/43,560 = .378 acres) - approx. 1/3 of an acre.
Flat Edged Ponds: Surface acres = length (Feet) * width (Feet) / 43,560
