i am pretty much doing that right now. my"sump" is a 10 gallon aquarium that i put baffles in. the fist chamber is where the water comes in. the chamber next to that is for the skimmer. the middle of the sump has about 10lbs of sand and about 8lbs of rock. i took a couple of scoops of the sand from my main to seed this sand in the sump. the last chamber is where the return pump sits. my sump has tons of pods
in it. so i guess that is the long way of saying yes it will work
