FORMULAS FOR DETERMINING GALLONS TO TREAT:

Formula for rectangular or square container:

(L x W x D = cubic feet x 7.4805 = gallons of capacity to treat.)
[Multiply length (m) x width (m) x average depth (m) = cubic meters]

Formula for round container:

(Diameter x diameter x average depth x 5.9 = gallons of capacity to treat)
Π r2 h1 = m3/ft3 (Π=3.14)(r = radius in m/ft) (h = height is m/ft)
