How Many Square Feet?
This one here's a handy little diagram to help in sizing tanks and distributor systems and laterals and media beds... and don't it sure look purty too?
Square Feet per Tank Diameter         The black type lists the total square footage (area) of tanks with diameters of 1 to 10 feet.

The red type lists the additional square footage each increasing tank size has above the previous tank size.

EXAMPLE: A 12 inch diameter tank (yellow center area) contains 0.79 square feet total, and a 24 inch diameter tank (light yellow area) contains 3.14 square feet total, which is +2.35 square feet larger than a 12 inch diameter tank.
(0.79 + 2.35 = 3.14)
If you have an unscientific idea that you would like to share with your fellow water quality improvement professionals, by all means let us hear it so we can pass the information along. Design by experience and evolution can be more reliable than what the eggheads can do in the lab or on a computer. We here at SWT believe that knowledge is meant to be shared. We do not presume to know more than our customers, and we really enjoy the exchange of ideas. You may e-mail your idea(s) to us at fieldnotes@swtwater.com.
