Little tip, get "spa flex" pipe, it's flexible PVC and joins to regular PVC fittings (better to use the clear cement though as it has a little more give than the grey). Get it at Western Pump, just ask for it at the counter, if you call it "flex PVC" they'll know what you mean.

The clear braided tubing you get at Home Depot/Rona/etc. is fine to use, but you need hose barb fittings (hose barb to MPT {"male pipe thread"} adapters). I think it's technically PVC as well but I just call that stuff vinyl tubing (again most people will know what you mean if you call it that).

When you're plumbing the sump return pipe (from the pump), make sure to use a small piece of flex PVC or the vinyl tubing between the pump and the sump wall (if you're using an inline pump, that is), to absorb vibration from the pump. This will make it less noisy, plus it protects the glass from any shocks (pump gets bumped) and vibration (worst case scenario it can break glass).
