I have a 1" closed loop and I'm using a Pan World 50PX-X (1110gph) on this closed loop.

Anyway, I want to reduce noise ( that pump is fan cooled ), electricity use, and increase flow.

So I was going to go with a Dart or something, but most bigger pumps need 1.5" intake ( Dart needs 2" ), so I kind of gave that up.

Then I looked at educators and thought about getting a pressure pump, but educators are HUGE..

So now I'm thinking of going the Seio / Stream route. They are a little smaller than the educators and use very little electricity and give lots of flow.

I'm looking at the Seios pretty seriously because they cost so much less. I was looking at getting 2 of the 1500 gph versions ( 34 watts each ). I think that with my WMD30RLXT ( 960 gph at 4ft ) would good flow for my 110.

I'm worried that it will be too much for the softies I have... namely my xenia. My wife would not want me to get rid of the xenia.

What do you think? Should I get the 1500s or 1100s or do something else?

I was going to put the Seio 1500s where the close loop inputs are now.
