One thing that I do, is Tee off one line to the planted sump, and another to the tank.
You dont need full pump force running thru the planted section.
You balance the flow thru the planted area, throttled back enough, to not overwhelm the planted area, and outflows, and .....the other teed line adding strong flow and agitation to the tank.
I just use PVC valves to control flow thru the planted area.
All centrifugal pumps can be throttled back on the output, you just don't want to choke them on the input line.
Here is another example. as you can see, the line and valve with water creating agitation in the tank, is wide open.
Behind it is a throttled back line controlling flow to a sump.
Below a close up of the slower flow, throttled back valve.
I like the ease of $4 valves, that if screwed up, is simply replaced by going to the hardware store,
as opposed to variable speed pumps, that if the variable speed component gets screwed up requires a major overhaul.
And like the others above, I always figure if the flow in, is coming from a 1" line, you always need at least 2 inches of leeway flowing out.
