Canister Filter Head loss

I'm putting an aquarium filter system together and I was thinking of using canister filters for the last stages. While walking through Lowes I noticed the canister filters for household water filtration and thought that they were cheap enough and easy enough to use. Now I'm trying to make a system curve to size my pump and I'd like to figure out the equivelent length of pipe or the head loss that one of these filters represents.

I suppose I could use a sudden expansion and then a sudden contraction, but what about the filter media itself (one of those wound tube or pleated filters)?

Thanks;

Josh

You'll really need to get that data from the supplier.

They have it, ask for the pressure drop clean and fouled, the equivalent length can be easily calculated from that data.
