You have to purchase a membership. It's about $325 for a family of 3 if you're coming from outside of the county. It's a bit cheaper if you live in the county but everyone pays to go to this pool. You can only come as a guest if you know someone with a membership who wants to bring you as a guest and that is limited to about 6 visits per member per summer.
I am a person from Philadelphia and we get the guest membership.
