How to Calculate Acre Feet

Average depth of pond x size in acres

For example, if your pond is 4-feet deep average and a 1/4 acre in size, you have one acre foot. If your pond is 1 acre in size and 12 feet average depth, you have 12 acre feet. This info is important for calculating need for aeration.

An acre is a little under 44,000 square feet.
So if you have a pond that is about 100' x 100' you have a 1/4 acre pond.

This easy to use product is available in several forms: as quick-dissolving powder in bulk or in water-soluble bags, as six-ounce pucks, or in 6 lb. blocks. The powder is perfect for treating an entire body of water, like your pond. The pucks are designed for easy spot treatments around docks or swimming areas. Both powder and pucks should be applied every 2-3 weeks when water temps are right. Use blocks for on-going time-release treatment lasting up to a month per block. To maximize the performance of this beneficial bacteria, please consider adding a Kasco aeration or circulation product. Again, this cart item is for the 8-oz bag, which treats 1/2 acre foot of water. There are so many different sizes available, please call us to order a different item.
