What size piping for a 1000 gal

I got a 1000 gal and I'm using a landshark 3300, what size diameter pipes should I be running

2" should do just fine. Maybe 2.5" if you're going a very long distance or it's a really low head pump.

well, you learn something every day; I didn't know they sold 2.5" pvc! I've never seen it at the big box stores, but sure enough--you can get it!

I have a 1500-2000 gallon pond, I'm using 1.5" pipe, with a Laguna 4500gph pump. My big pond is about 6000 gallon, with 2" pipe, and 86gpm pump. They both seem to be doing fine.
