The 2211 definitely provides way more flow than a ZooMed 501. Those numbers from ZooMed must be from some other universe.
If you use lily pipes with a 2213 on an Ebi, you won't even have to turn flow down. Just know that the dimensions of the tank are such that it could be difficult to get any sort of flow going near your substrate. I had difficulty with several different pipes and ended up just using a spray bar.
