The $80-90 fluval 404's appear to be all sold out on ebay now so I'm looking at switching to the Eheim 2215. Folks had originally said to get the 2217 I was looking at getting 2x2215's.
1 x 2217 = 264gph
2 x 2215 = 328gph
Plus side to 2 x 2215's would be 2 intakes to cover a wider area of the tank for sucking up debris. Also, would I have more biological surface area with the 2x2215 vs 1x2217? For folks who don't know there is also an emp400 on the tank, which is 75gallons,
