Hey all, I'm looking for an excellent submersible sump pump in reliability, energy efficiency, low noise and decent price. Need to be able to handle 800 to 1000 gph, capable of at least 4 ft of head. I'm using a rio 3100 but not too happy with its performance, what do you all recommend?

Mag 9.5 @ 4ft = 800
Mag 12 @ 4ft = 1100

Now reality is that you take hose length plus standpipe length to get full head height or if the hose goes from the pump directly to the top of the tank, use the whole hose length.

When I look at a pump attached to reef ready tank, most people (incl myself) use 4ft of hose under the tank, and the standpipe is about 2-2.5ft, which gives a total length of 6ft.

Mag 9.5 @ 6ft = 720
Mag 12 @ 6ft = 950

Mags have been extremely reliable for me and several others I know use Mags that have latest a very long time.

To compare this to the Rio 3100 plus unit. Rio 3100 @ 6ft = 500gph
Another thing you need to be aware of is that the Rio 3100 uses a 1" connector. The Mag 9.5 and 12 both use a 3/4" connector. Your hose might not be the same. You will most likely need to change out the hose if you change to the more power full Mag pumps.
If your tank is reef ready, then you are going to end up needing a 3/4" connector because this is the std AGA / Oceanic return line connector size.

Hope this helps
Jesper

I had a rio on my 6footer....wasn't happy either.

ehiems and mags are the best to go with. I have both and they are work horses.

I've been using Quiet One pumps for the past 18 months, with no problems. they were, at least the last time I bought one, a little cheaper than the Mag's and use a little less electricity . . ..

Hmm, thanks again guys. The mags are great but I wanted to try another brand with less wattage. So my current choices are between the Eheim 1262 Hobby or the Ocean Runner (friend swears by it and relatively cheap) but I suppose I can keep the Rio 3100 until it dies (but I do hate this piece of crap).
