Hey MFK ! First time posting , I have a 125 gallon and looking to sump it with a 75 gallon , now I want about 2000 gph or 10× turnover rate. I'm gonna use a Pvc overflow, I read that 1.5" PVC is 2100 GPH, Is that okay? What size pump should I need? Or should I do 2" PVC for the overflow?
125 Gallon with 75 gallon sump?

You don't need a sump that big. A 40 breeder at most is what you'll need. I'm using a 75 on my 210, and that is still considered overkill.
The only reason I'm using a 75 is cause I already have it with me. It's going to be a wet dry sump.
A 75g is not overkill on a 210. Over kill would be a 150 sump under the 210.
A 75 will work nice under your 125g. What is your stick going to be?

You need a sump big enough to hold your pumps, bio-media, and filtration media--bio-balls, pads, filter socks, whatever you use.
If that means a 75 gallon sump, then you put a 75 gallon sump. If you can fit all that in a 30 gallon box, then put a 30 gallon sump. The amount of water in the sump is a secondary benefit--more water is better because it dilutes bad chemicals. but it's not what you aim for when you size a sump. You aim for a box big enough to hold your stuff.
There's a very broad rule of thumb--sump is 20% of the display tank volume. But that's a starting point, not a strict rule.
