I am having a new (display) tank of almost 100 gallon. And i was looking into many pumps. But not sure of which pump to buy; at what flow rate?. So, can anyone recommend?

My sump is about 60 gallon. The height of the return pump to the display tank is about 5 feet tall.

definitely check out panworld/blueline pumps. inexpensive, efficient, quiet. I used to run a 50px-x on my old 72g w/sump.

When I converted to my 180 I sold all of my old stuff EXCEPT that pump. I have no use for it right now, but I liked it so much I kept it just in case.

I think either a Mag 9.5 or 12 would do nicely. Eheim makes some good pumps too. Lots of opinions here.

Best wishes,

I am using a QuiteOne and I like it, Not too expensive and like the name says it is very quite ;-)

A good rule of thmb is to shoot for around 10X turnover in GPH. Therefore, I would try to find a pump around 1000 gph. I have had alot of luck with MagDrive pumps. They sit in sump, are ultra quiet, and don't seem to raise the temperature much at all. I have a mag 9.5 in a 90G. Therefore, I would go with a Mag 12, as a little over pump through the system never hurt.

Eheim 1260 or 1262 depending on how much volume you want to move through the sump and how much headloss that you will have.
I wouldn't try to pump 1000 gph through a 600 gph (max) overflow so be careful.
If your using a regular aquarium stand and the pump will need to pump the water up about 4 or 5 feet then the 1260 should work great. If you want a lot more pressure for some reason then maybe the 1262. If your sump is in the basement then you will have to do more research.
Eheim pumps are energy efficient, quiet, can be safely used inside or outside the sump without heat issues.

Eheim 1260 or a Mag 7 IMO. Most people suggest 5X max through the sump, or so I thought. A Mag 7 at 5 feet of head is roughly 420gph. Also, as mentioned above, your overflow can probably only handle 600gph, so if the pump exceeds that, you will need a ball valve on the pump (which pretty much defeats the purpose of getting a larger pump) or another overflow up top.
