identify filters

[erock14]

does anyone know how to identify the differnce between the-
hayward ec65 and the
hayward ec75

they share the same manual, i guess one is a tad bit bigger
one gets 6lbs of earth
the other gets 7 lbs of earth,

its because i dont know which one i have, the sticker has both model numbers w/ two circles,(like check boxes)one of which is supposed to be filled in, to let you know which one you have, and of course mine have not been filled in. so hopefully sombody could shed some lite on this and fill me in. LOL

Measure the tubes, EC 65 tubes are 13 3/8" the EC 75 tubes are 16 1/4" long
