which wavemaker should i buy.......????

Would you advise running the scwd with hard line or flex? Want to do it correctly so It will function the best and last as long as it can. As far as a pre-filter, I have the return pumps located after the Fuge. Tank drains into the skimmer, flows through 3 baffles through the fuge and then into the return area through a 1" screened (gutter screen). The tank overflows do have pre-filters on the before dumping into the sump.

Thank you for your time and quick reply.
