Hi;

Basic question, but I can't seem to find consistent info ...

I have an undrilled 55 gal tank and am about to add a sump to it ...
figure I'll use a Lifereef prefilter/overflow box.

What do people recommend I use for a return pump? What would be a
good flowrate? Would 500 gph be too much or not enough or just right?
;-) I'll likely send the output thru a SCWD or SeaSwirl.

- thanks
Dave

never seen one of these that pumped water,,,,,,,,,,,,,interesting.

duh, for the sump. it doesn't need to be pretty, is easily cut or drilled,
and you can get one of these tubs for about $5.

Hi Marc;

Thanks (as always) for your reply.

I had sent email to the guys at Lifereef and Sea-Swirl ... Ed at
Lifereef recommends a pump between 500 and 900 gph for the Slimline
prefilter/overflow box I was considering. I was considering the 1/2"
Sea-Swirl model but they say the maximum flowrate for that model is
550 gph (the 3/4" model has a max flowrate of 850 gph).

Either a Mag 9.5 or a Mag 12 would work with that setup.

Hi Dave,

If you plan to use a SCWD on your return line, plan on the Mag 9.5 or Mag 12, because the
unit will reduce your output by 20%.

You also must take into consideration how high the water must be pumped into the tank from
the pump. 3', 4', or more.... it changes the output quite a bit. Add a few elbows, check
valves, etc.

I have a Mag 9.5 on my 55g for my return pump, but it goes into a 1" line that has a single
output. It is pushing about 800gph or so into my tank, and I can't run it fully open as my
overflow box can't keep up. By adding an extra Tee into the return line, with an elbow and
a ball valve, I redirect some of the water right back into the sump. And I also feed a
little water into my refugium from that return line, too.

If you use a Sea Swirl, you might not need as powerful a pump because there isn't as much
flow restriction through those, compared to the SCWD.
