Good 500 GPH Pump?

[KaiserSousay]

With sump normally below the tank, yes, I`m talking about a vertical pumping system.

These pumps have worked well for me.
I got them because you can run them submerged or inline.
The down side is, they lose GPH pretty rapidly as the head increases.

Via Aqua 2600 (740gph model), I have two of these runing my 120's 30 gallon sump. although I'm sure they're 500gph by the time they reach the tank, But I don't really care, got mine for 30$ a piece, a little over 1000 gph for 60$!

No problems yet either, run 24x7 and no problems starting them up after feeding time. They are covered in a light oil when you get them though, so they require a slight rinse off before use.
