New here and trying to be helpful... the specs on the Mastercraft you show seem like serious overkill. For my ponds and my aquaponics I use PondMaster Mag drive pumps, they are not the cheapest but I've never had one fail.. the impellers occasionally wear out but I can still get parts for 15 year old pumps.
(BTW I have no affiliation with anyone related to these guys)
