plumbing

[Moonstream]

I need help plumbing my nano. I have a 29g reef soon to be upgraded to a 20g fuge and 15g frag tank. I have the basic plumbing but need some help to finish the plan. the 29g will have a drilled overflow, that will run into the 20g, the a powerhead will push it up piping into the 15g frag tank, then another powerhead will push it up into the main tank. sound okay? piping will all be 1/2" and the overflow will be suronded by a 4" PVC pipe cut in half, w/ teeth.

What exactly are you looking for help with?
Why not cascade your overflow from 29 to 15 to sump, then pump it back to the tank. This way you save by using only one pump. You could also split the drain to go to sump and 15g frag tank then overflow from 15 to sump.

just thought I would run it by people who actually know about this stuff, I really have very little experience w/ this and wanted to make sure that I wasnt making some mistake (parents would kill me if this crashed so soon). I like the idea of splitting the overflow, and think I may go w/ that.
