I am not trying to knock you pumps just letting you know the route I was taking for some info...but im not sure if what im reading online is accurate for the barracuda now I have seen different #'s and it dont seem to work out math wise with (amps * volts = watts). For the barracuda I will have a gate valve inline to adjust the flow to what I need.
So your flip a switch idea has me think of something...how will the 2 pumps be plumeb...will you have one going to its own return or will you have them T together to one return. I ask becasue if you have one per return and you turn one off it might alater your flow in the tank and make dead spots and make you redo you return...and if they are T'ed then you might get water flowing back through the off pump (I guess). Just thinking outloud and trying to trouble shoot...thats what I try to do on mine when im thinking of how to run the pipe.
Man I really like your sump....hmmm lol
What kind of fish are you going to do?
