To Clarify: 2x return. Talking about return pumps. 2x return through the sump.2x what, sump or system?
OP's first post stated "10x sump turnover rule is archaic".
There are recommendations out there that mention using the return (located in the sump) to turnover the water 10x. Which is an archaic rule from back when power heads were large unsightly and gave relatively little water movement compared to size and power consumption. Its 2020 some "rules" need adjusting. Just like computers equipment is out dated in a year or two.
