What size do I need?

To calculate the volume of your water body and thus determine the size of Water Wych that is best for your pond or water feature, use one of the formulas given below. Remember, you cannot overdose with Water Wych - a larger one will work more quickly and last longer! For rectangle and square ponds Basic Formula:  Length x Width x Depth (measured in feet for conversion to gallons or metres for conversion to litres) x conversion factor. Imperial Gallons Length x Width x Depth (in feet) x 6.25 = Imp Gals. US Gallons Length x Width x Depth (in feet) x 7.5 = US Gals. Litres Length x Width x Depth (in meters) x 1000 = Litres. Gallons to Litres Imp Gal=4.546 Litres. US Gal = 3.7854 Litres. For circular and oval ponds Basic Formula:  Radius x Radius x Average Depth (measured in feet for conversion to gallons or metres for conversion to litres) x conversion factor. Imperial Gallons Radius x Radius x 3.142 x Average Depth (in feet) x 6.25 = Imp Gals. US Gallons Radius x Radius x 3.142 x Average Depth (in feet) x 7.5 = US Gals. Litres Radius x Radius x 3.142 x Average Depth (in meters) x 1000 = Litres. Gallons to Litres Imp Gal=4.546 litres US Gal = 3.7854 litres
