Prefilter Size for Canister Filter

[xuan87]

I recently decided to get a simple prefilter (will just stuff with white filter wools) to try to keep my Ehiem 2213 cleaner. Will like to ask if there is any calculation or things to get into consideration when choosing the best prefilter. I was thinking that a prefilter that is too big may lower the flowrate of the 2213.
