I already have a AM3600 on my CL and bought the AM2100 with my tank. CAme across the 3600 from SalsaKing after I ordered the 2100. I just dont want to run 3 pumps, seems a bit excessive to me. Then there is the new theroy (to me) about having your skimmer pump pull from the "in" side of you sump, which would mean the need for three pumps. I dont know what to do .big t said:So why don't you want to use both the pumps? I would put that ampmaster on a closed loop, and use the iwaki for your return. Then pick up a smaller iwaki like the 20 for your skimmer. I am not sure what kind of pressure/ flow requirements your skimmer have.
Have any suggestions? Last pressure pump I used was a Quiet One on my 60.Schottman said:sell the 2100 and rlxt40 and get a good preesure rated pump to run the skimmer and your return
