Thanks for the comments.

I most likely will go with Dave again for the discus tank. They are still small juveniles (less than 4 inches) so it will be awhile before they move to their new home. I'm also planning on having the exact same setup for the discus tank, except I will also incorporate two canisters to it. The sump will be a refugium for hornwort and auto water change.

The Eheim 1262 has to run 11 feet horizontal and up 5 feet total (gradual slope).
