overflow flow

[outtafocus]

I decided to go with a Rio 20HF return pump, it puts out excellant flow. I do believe my plumbing set up is limiting my potential flow, and I just dont like the way I did it. So I will be replumbing my return.
Has any one tried or know of a good place to pick up Spaflex or similar pvc tubing? This could elliminate many unnecessary 45's and 90's.
