Water Temperature
Width of raceway
Length of raceway
Water flow in gallons per minute
Exchange Rate 2’ (depth) x 4’ (width) x 25’ (length) = 200 cfw
200 cfw x 7.48 (gal/cfw) = 1,496 gal water
75 gpm x 60 min/hr = 4,500 gph
4,500 gph / 1,496 gal water = 3.01 exchanges per
hour
1.5’ (depth) x 4’ (width) x 25’ (length) = 150 cfw
150 cfw x 7.48 (gal/cfw) = 1,122 gal water
75 gpm x 60 min/hr = 4,500 gph
4,500 gph / 1,122 gal water = 4.01 exchanges per
hour

0.5% Salt Treatment
Lbs. of salt = 1.25 lbs. of salt x water flow (gpm)
Lbs. of salt = 1.25 lbs. of salt x 150 gpm = 187.5
