I don't need an adapter to take it from some other side up or down to 1"?

If so, that should make things easy

Sorry, I thought it was 1" already. Been awhile since I've used an Eheim. You'll need a 3/4" adapter, and run 3/4" pipe from the pump to the tank. Generally, you should use the same size pipe as the output of the pump. The manufacturer chose that size for a reason. If the tank's bulkhead is a 1" then you'll need a 1" x 3/4" slip reducer bushing to slip into the bulkhead.
