anyone piped their tank with Aryclic tubing or Clear PVC?

What's a vortex? Also why would it be hard to adjust if the magnets are inside the overflow? I figured it would hide it all. Was even going to run the wires through overflow. If I made the width of the overflow skinnier and placed the heads on the glass wouldn't the wall of the overflow partially block the current?

Also you think the two powerheads are good enough controlled by a apex or should I get the 6205.

Thanks for all the help btw. Just want to get the correct parts the first time.
