Please help on sizing pump

[rdefino]

I have a 210gal tank that will be on the 1st floor. The sump will be in the basement below. I measured and the return line is about 12ft long. Since there are 2 overfllows, I will need to split the line to each.

Now I'm a little confused on how to size the pump need for the return. Could someone please help out?

I also ran 4 hard lines in the wall. 2-2" 2-1.5" Not sure if I need all these, but is was easy when the wall was open.These are included in the measurement.
I plan on using flexible lines to minimize using 90degree bends.

Thanks for all the help guys

Now this ask me for the pump I'll be using, But I don't know which one is correct to use.

Plug in your plumbing information then mess around with the different pumps till you find one that suits you.

When you say "find one that suits you" How will I know if the pump is the correct one?

thanks

Am I looking for one that gives me so much GPH of flow? Should I be looking for about 10 times the tanks volume?

Depending on who you ask, some will say 3 times your tank volume and other will say up to 10.

I think I'm running around 5 times on mine. I haven't got my inline flow meter installed yet so I'm just guessing.
