Abs isn't made for pressure systems. Abs is used for gravity systems so if its the pipe to the sump you would be ok but the return use PVC. Size of pipe depends on how much flow you want and how big the pump you are gonna be using is. Remember the smaller the pipe the less flow. I personally use 1" with a rio 2100 for my return on a 65 gallon and it is plenty.

I know PVC is for pressure but don't think there will be that much in it and I have the plumbing to go to and from the skimmer but I'm building the skimmer and need to know what if it makes much difrence what size pipe goes up into the collection cup

As long as it can handle the flow of water your tank will be getting it shouldn't. The largest particles of anything going through filter is usually food so you technically could use 1/2" if wanted and flow permitted.
