I wish I could help more, but...
J have a 2400gph Reeflo pump that has been running a Ocean Motion 4 CL for 4 years. It has had an issue and Reeflo was great with customer service. But now it is getting loud, so I have ordered some Jebao DC12000 pumps. One for the CL, one for my in supm and one as a back up. It is a new pump and a somewhat suspect manufacturer, so I got a back up and I'll keep my Reeflo just in case. But they were so cheap in a group buy that I couldn't pass them up.
When they arrive I'll post pics of the install, but I think I'm still 2-3 weeks out from delivery. Like I said, I wish I could help more...
