[garwood]

hi, could really use some help. i got a 3 x 2 x 2 aquarium with a 30 gallon sump. the height between the bottom of the sump and top of tank is 5' 4". the return has a couple of 90 elbows over top of tank bringing output into tank. would like the ability to add acouple of reactors etc in the near future. im not looking for high flow through the sump prob around 5x. i am running a sro1000int skimmer also. pls suggestions would be greatly appreciated.
