Pond Volume Explained

Pond Volume Explained
  Where do we start?....
  Pond size! First... we need to establish the size of the pond to calculate its gallonage. Unless we get this right everything else will be a waste of time. The size of the pond governs the amount of water to be filtered.
  How do we calculate this?
  The diagrams above shows a simple way to assess the volume of an irregular shape by breaking it down into smaller sub units.
  In this example the pond has been divided in two main sections A and B. Measure each section in feet. All figures should be rounded UP to the nearest whole foot. For filtration purposes you would be better to over estimate the volume. (This only applies to filtration calculations and NOT for medication. It is GOOD to over filter but BAD to over medicate). The volume of each section is calculated using length x width x depth. This gives us an answer in cubic feet. Each cubic foot holds 6¼ gallons of water. The volumes of the two sections (A & B) should then be added together to give the total cubic capacity. This is multiplied by 6.25 to give the total volume in gallons.
  Do not under estimate the size of your pond!
