1. you mentioned the water enters from the bottom, so what is pulling that water in from the bottom? i dont think there is a second pump at bottom ! or maybe you fill the canister with water ahead of time, which would make more sense......lol at least for me it does right now. could be wrong.
yes, to prime the filter you need to fill it up. but since it has those valves on the hoses for easy cleaning it will prime itself when you leave the hoses filled up in the aquarium. there is only one pump at the top which shoots the water out, the water flows in the canister by siphon. if you got more questions let me know.
