That's basically what I did so obviously I agree 100% with your ideas LOL ... one other note, avoid 90 degree elbows like the plague, you can buy what are called "sweeps" for making 90 degree turns and they use about half the "head pressure" of a regular 90 degree ell fitting. I didn't and boy do I regret it now, it's cut the return from my pump by almost half

The sweeps are not as easy to find but if you look online or in a *good* plumbing supply you can find them. Just a suggestion that I wish I'd been given before I got this thing all put together.
Good luck and remember to post pics as you go
Later,
