900 gph @ 12'
4.3 turnovers

That's good enough in my book. By the way, the bashing that I am about to get for saying that is based on conjecture and/or what someone else said.
 
taking Chompers data at face value (which i am willing to do)

that does not include pressure loss due to pvc fittings

why not put the sump under the stand like normal?

note: most of my "water on the floor" events come from the tank itself (and you will have them, o yes you will)
 
I used an Iwaki MD100-RLT for my return pump when I had my sump in the basement. I believe it is rated at around 1500GPH at 20' head.
 
I meant to attach this.

I think Iwaki makes the best aquarium pumps. There are lots of cheaper pumps, but none better, in my opinion.

i want it in the basement because i want the sump to be bigger. plus the noise factor and easy to maintain. oh and the extra security fromf a flood. got the return down to 9'. will post pics once compleated. thanks guys.
 
I have had a few tank set up with quite a lift from sump to tank and I have found that you first need a good pump meant for more lift than you need and to get full potential as far as flow is to use a return line that is not much larger than the pump out let and have it go straight up with no fitting and what I used to do is heat up a lenght of pvc over a stove element and bend it slowly into a soft flowing bend for the top. this seemed to make the best use of the pumps potential.

Tank is on the 3rd floor sump is in the basement, he says it is a 1 or 2 hp pump.
So what you are doing is cake compared to this dude.
Just do your homework and you should be fine.
Also most people don't think of there overflow rate like my overflows are rated at 600 gph times 2 so i have a max flow rate of 1200 gph, so what I'm saying don't go to high either because you can only suck so much water from the tank.
So head plus flow rate is key, good luck.
 
That system must be in a warm climate. I'd have trouble running my lines on a outside wall here in canada thats for sure
