You can consider getting a glass intake with integrated surface skimmer.

I used one on one of my old scapes worked a treat, you can get them relativity easily and cheaply now, thou when i first used tone they were not that common.
Work so well that i opted to use one on my new scape, thou this time round i am using Stainless steel pipes.
I've also considered this option. Although I really like having the skimmer externally for easy cleaning and extra flow... also I'm really happy with the performance of my Cal intake, so will wait and see what insane price ADA will put on the new Vuppa
