Blue line pumps?

[Fish]

Hey. I'm a huge fan of blueline pumps, I've had an 20-hd as a return from my sump for the last four months and it runs perfectly. They are reasonably priced, pressure rated, and run super quietly. I can't even hear it when my stand is closed.
I recently picked up a used japanese iwaki 20rxlt? (the circulation one) in an ebay auction and plan on using that as a return and putting my blueline on a closed loop. Once I have them both running I will let you know how they compare but I will tell you that I have taken them both apart and they appear to be identical designs. If I had to buy another pump (hopefully not though) I wouldn't get anything other than blueline.
HTH.
