Yeah could be...That is the best way to do it, but you won't hurt the pump by restricting the outflow until you get quite close to zero flow. Throttling the suction is a bad idea though, which may be what you were told.
it worked out great for me as I was able to build my sump with just 2 chambers. The right side is the refugium with my HOB AquaC skimmer. The second return line fills that section slowly and the water overflows into the return pump section on the left over the wall.
Works for me though I MUST use a filter sock as I do not have the standard bubble trap.
