I have a 240g that I am setting up with a heavy bio load. I will have 2 hard plumbed eheim 2260's on a single closed loop and another closed loop with a fluidized bed filter, a blueline HD40x pump and an fsi x100 inline bag filter. The question I have is about the order of the second loop. I though that to avoid pulling the solid waste through the pump that I would have the flow go tank --> fsi x100 --> blueline pump --> fluidized bed --> tank. The plumbing is 1.5" PVC although it will step down to 1" at the blueline and fluidized bed filter. Do you see it a problem that the blueline will be "pulling through" the bag filter rather than pushing?
